Ukulandela isimo sezemvelo esishintsha ngokushesha okukhulu akusona umsebenzi olula kubaqhubi bezimboni, abaphathi bezimboni, kanye nezikhulu zezokugcina imvelo. Imithethonqubo emisha ivela minyaka yonke, ubuchwepheshe bokuhlanzeka bukhula ngokushesha, futhi okulindeleke kubabambiqhaza mayelana nomthwalo wemfanelo wezinkampani kuya kukhuphuka. I-Haidi Environment (Tianjin) Co., Ltd. ishicilela lesi sikhungo sokuphawula kochwepheshe ukuze isize amabhizinisi ukuba ahlukanise amaqiniso emsindweni futhi aguqule izibopho zemvelo zibe amathuba okusebenza kahle. Ezihlokweni ezingezansi, sihlola izinto ezintsha zokuhlunga ngolwelwesi, ukuzulazula ekuthobeleni imithethonqubo, ukuqaliswa kokukhishwa kwamanzi okungenalutho, kanye neqiniso lansuku zonke lokuphathwa kwekhwalithi yomoya. Isihloko ngasinye sisekelwe kulwazi lwangempela lwephrojekthi futhi sisekelwa iziqondiso ezingokoqobo abafundi abangazisebenzisa ngokushesha ezikhungweni zabo.

Ukushoda kwamanzi kanye nokukhuphuka kwezindleko zokulahla amanzi kuye kwaphoqa ukuthi ukusetshenziswa kwamanzi kabusha ezimbonini kungabe kuseyinto yokuzikhethela, kodwa kube yinto ebalulekile okumelwe yenziwe kubakhiqizi emhlabeni wonke. Ubuchwepheshe bokuhlunga ngamangqamuzana (membrane filtration), ikakhulukazi i-nanofiltration (NF) kanye ne-reverse osmosis (RO), buyisisekelo sezinhlelo zesimanje zokuvuselela amanzi, ngoba bukhiqiza amanzi ahlanzekile asezingeni eliphezulu ngokuqhubekayo emithonjeni eyinselele. Intuthuko yakamuva ezintweni zokwenza amangqamuzana ikhuphule kakhulu izinga lokukhipha usawoti, kuyilapho yehlisa amandla adingekayo ukuze amanzi adlule ebusweni bokuhlunga. Ukumelana nokungcola, okuyinkinga enkulu ezinhlelweni zakudala, nakho kuthuthukisiwe ngezindlela ezithuthukisiwe zokuguqula ubuso bamangqamuzana, okunciphisa imvamisa yokuhlanza futhi kwandisa isikhathi sokusebenza kwamangqamuzana. Umphumela ukuthi izimboni ezisezinkambeni ezinjengokudaya izindwangu, ukucubungula ukudla, nokukhiqiza izinto zikagesi, manje sezikwazi ukubuyisela amanzi angaphezu kwamaphesenti angu-85 okuwasebenzisayo, ngezindleko ezinengqondo kwezomnotho.

Konjiniyela bezimboni abahlola lokhu kuthuthukiswa, ukhiye uwukufanisa uhlobo olufanele lwe-membrane ne-chemical yamanzi ethile endaweni, ngoba amanzi anosawoti, amanzi olwandle, kanye nezinhlelo zokucindezela okuphansi ngakunye kudinga ukwakheka okuhlukile. I-Haidi Environment Imikhiqizo1Ukunikezwa ngaphansi kohlu lwe-Eco Water Solutions kufaka phakathi i-NF, i-RO, amanzi anosawoti, ukukhipha usawoti emanzini olwandle, kanye nemikhiqizo yama-membrane anomfutho ophansi elungiselelwe lezi zimo ezahlukahlukene zokungenisa amanzi. Ngaphandle kokukhetha imishini, amaphrojekthi aphumelelayo okuphinda asebenzise amanzi adinga ukuklanywa ngokucophelela kokwelashwa kwangaphambi kokuvikela ama-membrane ezinhlayiyeni, ezintweni ezakha amandla, nasekukhuleni kwezinto eziphilayo obekungenza kunciphise impilo yemishini. Ukuqapha ikhwalithi yamanzi acwengekile ngama-sensor angaphakathi nokwenza ukuhlanza ngezikhathi ezithile ngokusekelwe emininingweni yangempela yokusebenza, kunokulandela izikhathi ezimisiwe zekhalenda, kuqhubekisela phambili amazinga okuthola amanzi. Lapho zonke lezi zinto zihlangana, izinkampani zivame ukuthola ukuthi imbuyiselo yazo yokutshalwa kwezimali ifika ngaphansi kweminyaka emithathu ngenxa yokuthenga amanzi ahlanzekile okunciphile kanye nezindleko ezinciphile zokwelashwa kwamanzi angcolile. Njengoba imithetho iqina mayelana nemikhawulo yokukhishwa kwamanzi, ukuphinda kusetshenziswe ama-membrane kuya kuba yindlela evikeleke kakhulu neqhubekayo yokukhula kukhiqizo okuqhubekayo.

Umthetho waseChina wokulawula imvelo uthuthuke ngesivinini esimangalisayo, usuka eziqondisweni ezijwayelekile ezingaqiniswanga ngokuqinile uye ezimfunweni ezinembile, ezisekelwe edathini, eziphethe izijeziso ezibalulekileyo kulabo abangahambisani nazo. UMthetho Wokuvikelwa Kwemvelo obuyekezisiwe, kanye nezindinganiso zokukhishwa kwezinto ezingcolisayo eziqondene nomkhakha othile, manje udinga ukuthi abasebenzi bezimboni bagcine amarekhodi okuqapha angenzelelwanga, bafake amathuluzi okuhlaziya aqhubekayo axhumeke ku-inthanethi ezimweni eziningi, futhi babike idatha yokukhishwa kwezinto ezingcolisayo ngokucaca okukhulu. Amabhodi endawo okulondoloza imvelo enza ukuhlolwa okungamemezelwanga, aqinisekise idatha yezikhungo ngokuqhathanisa nokubonwa kwamasathelayithi, futhi ngokuya esebenzisa isibopho sobugebengu kubaphathi abafihla ukwephula umthetho ngamabomu. Ezinkampanini zamazwe ngamazwe ezisebenza eChina, lokhu kusho ukuthi ukuthobela umthetho akusekwazi ukuphathwa njengodaba olungokomthetho lwasendaweni kuphela, kodwa kufanele kuhlanganiswe ezinhlelweni zomhlaba wonke zokuphatha imvelo nasezinkambisweni zokucwaninga ngokuzithandela.

Ukuthobela okusebenzayo kuqala ngokuhlaziywa okuphelele kwezikhala okuhlola ukusebenza kwamanje ngokuqhathanisa namazinga amasha kakhulu okukhishwa komoya, amanzi angcolile, imfucuza eqinile, nokuphathwa kwezinto eziyingozi. Izikhungo kufanele zibe sezibeka phambili izenzo zokulungisa ngokusekelwe ebungozini, ziqale ngezinkinga ezingadala ukuvalwa ngokushesha noma izinhlawulo ezinzima, bese ziqhubekela ekuthuthukisweni kwengqalasizinda yesikhathi eside. Ukuqeqeshwa emlandweni wokubhalwa kwezinto kubalulekile ngokufanayo, ngoba abahloli bavame ukufuna ubufakazi bokuqeqeshwa, amarekhodi okulinganisa, kanye nemibiko yokuhlola yomuntu wesithathu ekhombisa isiko lokuthobela kunokuba nje ukuthobela emaphepheni. Izinkampani eziningi ezibheka phambili zikhetha ukuya ngalé kwemfuneko eyisisekelo ngokwamukela izitifiketi zokuzithandela kanye nezinhloso zokusimama kwezinkampani, okungabavikeli ekucindezelweni okuzayo kwemithethonqubo futhi kuqinise ubudlelwano namakhasimende. I-Haidi Environment isebenza njengozakwethu kulolu hambo, futhi thinaIkhayaIkhasi lichaza ukuthi indlela yokusebenzisana ekuphathweni kwamakhemikhali nokunakekelwa kwamanzi isekela kanjani ukusebenza okuhlanzekile. Ukuhlala ngaphambi kwesidingo ekuthobeleni imithetho ekugcineni kuvikela ukufinyelela emakethe, kugcina isithunzi somkhiqizo, futhi kunciphisa ukungaqiniseki kwezimali okuza nokulungiswa okwenziwa ngemuva kwesenzakalo.

Ukukhishwa kwamanzi okungenalutho (ZLD) umele umkhawulo omkhulu kunayo yonke emkhakheni wokuphathwa kwamanzi ezimbonini, lapho kungekho manzi angcolile avela enqubweni aphuma esikhungweni njengoketshezi olungcolile. Esikhundleni salokho, izinhlelo ze-ZLD zibuyisela cishe wonke amanzi ukuze asetshenziswe futhi aguqule izinto eziqinile ezincibilikile zibe yikhekhe eliqinile eliyalahlwa emhlabathini noma umkhiqizo onenani eliphezulu osetshenziselwa izinzuzo. Uhlelo olujwayelekile lwe-ZLD luhlanganisa ukuhlanzwa kwangaphambi kokwelashwa, ukugxilisa amanzi ngohlelo lwe-RO, ukuhwamuka ngokushisa, futhi ekugcineni izinto ezikhiqiza udoti oqinile, lapho isigaba ngasinye saklanyelwe ukunciphisa ukusetshenziswa kwamandla nezindleko zokwakha. Nakuba lezi zinhlelo ngokwesiko zazigcinelwe izikhungo zikagesi nabakhiqizi bamakhemikhali abanazo izinkinga ezinkulu zokukhipha amanzi angcolile, imiklamo ehlukanisekayo nevuselela amandla yenze i-ZLD yasebenza ezinkambisweni eziphakathi nendawo ezibhekene nemithetho eqinile yokuvimbela ukukhishwa kwamanzi angcolile.

Ekuhleleni kwakamuva okusekelwa ithimba leHaidi Environment, umkhiqizi wamakhemikhali akhethekile wafuna ukuqeda ubungozi obukhulayo bokuthobela umthetho obulethwa amanzi angcolile anosawoti omningi owedlula amazinga amasha okukhishwa kwawo asemthethweni. Ngemva kokuhlaziywa okuningiliziwe kokulinganisela kwamanzi, onjiniyela bethu baklama uhlelo olunezigaba ezihlukene olwaqala ngokubuyisela amanzi ahlanzekile ngokugxilisa ulwelwesi, base begcwalisa usawoti ogxilile kumshini wokuhwamukisa umhwamuko osebenzisa ingcindezi yemishini, onelungelo lobunikazi ngenxa yokusebenzisa amandla amancane. Lo msebenzi wabuyisela cishe amaphesenti angu-90 amanzi angcolile angenayo njengamanzi enhle okusebenza, wehlisa kakhulu izindleko zokuthenga amanzi esikhungweni, futhi waqeda usongo lwezinhlawulo zokungathobeli umthetho ezazilokhu zikhula njalo ngekota. Izici ezibalulekile zempumelelo zazihlanganisa ukuhlolwa okubanzi kwesampula ngamanzi angcolile angempela endaweni, ukukhetha ngokucophelela kwamakhemikhali okulwa nokunqwabelana kosawoti nokulwa namagwebu ukuze imishini isebenze kahle, kanye nokuqeqeshwa okuphelele kwabasebenzi ukuze kugcinwe ukusebenza kahle ngemva kokunikezelwa. Inzuzo yezomnotho yaqina nakakhulu lapho inkampani iqala ukuthengisa umkhiqizo ongemuva kasawoti otholakele kumkhiqizi wendawo wezinto zokwakha, okwenza lokho okwake kwaba umthwalo kwaba umthombo wemali engenayo.

Izakhi eziguquguqukayo eziphilayo (VOCs) zihlala zingenye yezinselelo ezinkulu kakhulu zekhwalithi yomoya kubakhiqizi emikhakheni esukela kokokugqoka nokunamathelayo kuya kwemithi nokucwengwa kukaphethiloli. Lezi zakhi zinomthelela ekwakhekeni kwe-ozone ezingeni lomhlabathi, zibanga izikhalazo zephunga emphakathini ozakwethu, futhi eziningi zinezinkinga eziqondile zezempilo ezidala imikhawulo eqinile yokuchayeka emsebenzini. Ukulawula okusebenzayo kwe-VOC kudinga isu elinezici ezintathu: ukushintshwa kwe-solvent nokulungiswa kwenqubo emthonjeni, ukuthuthukiswa kokubanjwa ngokuthuthukisa ama-hood nama-ductwork, kanye nobuchwepheshe bokucekela phansi noma bokubuyisela ekugcineni kokukhipha. Izindlela ezisetshenziswa kakhulu zokucekela phansi zihlanganisa ama-regenerative thermal oxidizers ashisa ama-VOC emazingeni okushisa aphezulu, ama-catalytic oxidizers asebenza ngamandla aphansi, kanye nezinhlelo zokwelapha ngezinto eziphilayo ezifanele imifudlana ehlanjululwe, engaguquki.

Ukukhetha ubuchwepheshe obufanele bokulawula kuncike emthwaleni womoya, ukugxila kokungcola, ukwakheka kwe-VOC, kanye nezinga elifiselekayo lokucekelwa phansi, yingakho ukuhlolwa kobunjiniyela obuchwepheshile kuzikhokhela kaningi. Emigudwini enokugxila okuphezulu, ukubuyiswa kwe-solvent ngokufiphaza noma ukunanyathiselwa kuvame ukubuyisela izindleko zempahla ngokusebenzisa izinto eziluhlaza ezitholwayo kuphela. Abakhiqizi bavame ukungakunaki ukubaluleka kokugcina ama-capture hoods namapayipi, ngoba ukusebenza kahle okuphansi kokuthwebula kucekela phansi ngokuthula ukusebenza kwawo noma yimuphi umshini we-oxidizer oyinkimbinkimbi kakhulu ofakwe kamuva. I-Haidi Environment'sImikhiqizo iphothifoliyo kanye nezinsizakalo ezihambisanayo zisiza amakhasimende ezimboni ukuthi athuthukise zombili izijikelezo zokwelapha amanzi nomoya, ukuze ukuthuthuka emkhakheni owodwa wezemvelo kungadali imithwalo engahlosiwe komunye. Ngaphandle kokuthobela imithethonqubo, ukulawula okuqinile kwe-VOC kunciphisa izingozi zokuqhuma, kuthuthukisa ukuphepha emsebenzini, futhi kuqinisekisa ilayisensi yokusebenza emiphakathini ekhula ngokuya ihlola ukukhishwa kwezimboni.

I-Haidi Environment (Tianjin) Co., Ltd. muva nje iye yaqhubekisela phambili ukuzibophezela kwayo emiphakathini ehlanzekile ngokubambisana nohulumeni wesifunda sendawo ngohlelo lokuthuthukisa ikhwalithi yomoya endaweni yase-Tianjin. Lolu hlelo lwahlanganisa izikhulu zokuhlela zomasipala, abaqhubi bezimboni, kanye nonjiniyela bethu bezemvelo ukuze kutholakale amathuba okunciphisa ukukhishwa kwezinto ezingcolisayo anomthelela omkhulu phakathi kweqembu lezinkampani ezincane nezimaphakathi. Ngokuhlolwa okuhlanganyelwe endaweni, ithimba lakha imephu yemithombo yokukhishwa kwezinto ezingcolisayo, labeka phambili izindawo eziyingozi kakhulu kusetshenziswa imodeli yokusabalalisa, futhi lasebenzisa izindlela zokulawula ezingabizi kakhulu ezilethe ukuncipha okulinganisekayo onyakeni wokuqala. Leli modeli lokubambisana libonisa ukuthi ukuthuthukiswa okukhulu kwekhwalithi yomoya akubangelwa ukusebenzisa izijeziso kuphela kodwa kubangelwa ukubambisana kwezobuchwepheshe okusiza amabhizinisi ukuthi afeze izinhloso zezemvelo ngendlela ephumelelayo.

Ubambiswano lukhombisa umgomo obanzi we-Haidi Environment njengomlingani wakho wethembekile wezemvelo, ifilosofi eyakhelwe eminyakeni eminingi yolwazi kumakhemikhali okwelapha amanzi, ukuthuthukisa izinqubo, nobunjiniyela bokulawula ukungcola. Njengengxenye yalo msebenzi, ochwepheshe bethu bethula izinhlelo zokuphatha amanzi ezihlakaniphile ngaphansi kwe-Imikhiqizo1Isigaba se-Hydro-Intellect, sibonisa ukuthi amapulatifomu ahlakaniphile okufaka amakhemikhali kanye nokuqapha ngesikhathi sangempela kunciphisa kanjani ukumosheka kwamanzi kuyilapho kunciphisa nokusetshenziswa kwamandla okuhlobene nokushisisa amanzi nokumpompa. Siyaqhubeka nokwandisa le mibambiswano yomphakathi nezinkampani ezizimele ngoba iphindaphinda umthelela wezenzo zomuntu ngamunye ezinkampanini futhi idala umfutho wasendaweni obheke ezinhlosweni ezibanzi zokusimama. Abaholi bebhizinisi abanentshisekelo yokuthi lobu budlelwano bungazuzisa kanjani izifunda zabo bayakhuthazwa ukuthi babuyekeze izixazululo okuxoxwe ngazo kuso sonke lesi sikhungo sezindaba futhi baxhumane nathi ukuze bathole ukubonisana okukhethekile.

Ngaphezu kwamaphrojekthi athile avezwe ngenhla, kunezindikimba ezimbalwa ezihlangene ezichaza ikusasa lezixazululo zemvelo zamakhasimende ezimboni. Okokuqala, ubuchwepheshe obuluhlaza busuka esigabeni sokuhlolwa kwe-pilot buye ekusetshenzisweni okujwayelekile, ngezinhlelo zokulawula ezihlakaniphile, ukunakekelwa okubikezelwayo okuqhutshwa yi-artificial intelligence, kanye nama-digital twins okunika abasebenzisi amandla okuthuthukisa ukusetshenziswa kwezinsiza ngokunemba okungakaze kubonwe. Okwesibili, igebe lamakhono kwezobunjiniyela bezemvelo lisewumkhawulo wangempela, yingakho i-Haidi Environment itshala imali enkulu ekudluliselweni kolwazi, ekuqeqesheni emsebenzini, nasekubhaleni imibhalo yobuchwepheshe ngezilimi ezimbili okunika amaqembu amakhasimende amandla okusebenzisa izinhlelo ngokuqiniseka. Okwesithathu, ukubika ukusimama sekuba yimfuneko yezohwebo, ngoba abathengi abakhulu nabaxhasi bezimali manje sebefuna idatha yokusebenza kwemvelo elinganisekile njengengxenye yokuhlolwa kwabahlinzeki nezinqumo zokuboleka. Izinkampani eziphatha ukuphathwa kwemvelo njengomsebenzi wamasu, hhayi nje ukugcwalisa ifomu lokuthobela imithetho, zibika ngokuqhubekayo izindleko eziphansi zokusebenza, igunya lomkhiqizo eliqinile, nokufinyelela okuthuthukile emalini. Isikhungo sethu solwazi kanye nomtapo wezifundo ze-case study kunikeza indawo ekhulayo yalokho okuhlangenwe nakho okungokoqobo.

Siphinde simeme abafundi ukuthi bahlole ukusebenzisana kwezinsiza zokulahla imfucuza, ngoba izinselelo zamanzi, umoya, kanye nemfucuza eqinile zivame ukuhlangana ngezindlela ezidinga ukuhlela okuhlanganisiwe kunokulungiswa okwehlukene. Ukuthola inani emikhiqizweni eyinsalela yezimboni, ukuklama kabusha amaphakheji ukuze kuncishiswe ukukhiqizwa kwemfucuza, kanye nokusebenzisana nabagcini bokugaywa kabusha abagunyaziwe—konke lokhu kunomthelela endleleni yomnotho oyindilinga abalawuli abaya ngokuya beyivuma. Izinhlelo zokuzibophezela kwezenhlalo ezihlanganyela abasebenzi nemiphakathi eziphathwayo ziphinde zikhulise ukwethembeka kwezimangalo zemvelo futhi zibe lula imvume yomphakathi edingekayo ukuze kwandiswe izikhungo. Njengoba isimo sokulawula nobuchwepheshe siqhubeka sishintsha, ukuhlala unolwazi kuseyithuluzi elisebenza kakhulu lokulawula ubungozi elitholakala kubathathi bezinqumo bezimboni.

Izixazululo zemvelo ziyimikhiqizo ehlanganisiwe, izinsiza, kanye namasu obunjiniyela asiza izinkampani ukuphatha ukukhishwa komoya, amanzi angcolile, imfucuza eqinile, nokusetshenziswa kwamakhemikhali kuyilapho zihlala zithobela imithetho futhi ziqhudelana. Ezinkampanini eziningi zezimboni zibalulekile hhayi nje ngoba imithetho iyala ukusebenza okuhlanzekile, kodwa nangenxa yokuthi ukusetshenziswa kwezinsiza ngendlela efanele kunciphisa ngqo izindleko zokusebenza futhi kuvikela isithunzi somkhiqizo. I-Haidi Environment (Tianjin) Co., Ltd. ihlinzeka ngesiqondiso esikhethekile esihlanganisa amakhemikhali okwelapha amanzi, ukuhlunga nge-membrane, ukulawulwa kwe-VOC, kanye nokusekelwa kokuthobela imithetho. Izixazululo zemvelo ezingochwepheshe ziguqula ingcindezi yemithetho ibe yinzuzo ezilinganiswayo yokusebenza, njengezindleko eziphansi zamanzi nokuthuthukiswa kokwethembeka kokukhiqiza. Ngaphandle kwazo, amabhizinisi asengozini yezinhlawulo, ukuvalwa, nokulahlekelwa ukwethenjwa ngamakhasimende.

Ukuhlunga ulwelwe, ikakhulukazi i-reverse osmosis ne-nanofiltration, kususa ngokomzimba usawoti oncibilikile, izinto eziphilayo, nezinhlayiya emanzini angcolile, kukhiqize i-permeate ehlanzekile engathatha indawo yamanzi ahlanzekile ezinqubweni eziningi. Ama-membrane elements anamuhla angangcoli kancane avumela izikhungo ukuthi zibuyisele amaphesenti angu-85 kuya kwangu-90 amanzi azo enqubo kuyilapho zisebenzisa amandla amancane. Imifudlana yokudla enamandla amakhulu okwakha amandla (scaling) ingalawulwa ngamakhemikhali afanele e-antiscalant nezigaba zokwelashwa kwangaphambi ukuze kuvikelwe indawo ye-membrane. Umphumela uwukuncipha okukhulu kokuthengwa kwamanzi ahlanzekile kanye nenani lokukhishwa kwamanzi angcolile. Uhlu lwe-Haidi Environment's Eco Water Solutions membrane lunikeza imikhiqizo ye-NF, RO, amanzi anosawoti omncane, kanye ne-seawater desalination ukuze ihambisane nezimo ezithile zendawo.

Isistimu yokukhipha amanzi engenalutho (zero-liquid discharge) iwuhlelo oluhlanganisiwe lokwelapha amanzi olubuyisela cishe wonke amanzi angcolile ukuze asetshenziswe futhi aguqule izinto ezincibilikile ezisele zibe yinsalela eyomile, evame ukuthengiseka. I-ZLD evamile ihlanganisa ukwelapha kwangaphambili, ukugxilisa ngolwelwesi, ukuhwamuka ngokushisa, kanye nokwakheka kwamakristalu ukuze kuqedwe ngokuphelele ukukhishwa kwamanzi oketshezi. Isetshenziswa lapho ukuvinjelwa kokukhishwa kwamanzi, ukushoda kwamanzi okukhulu, noma izinhlawulo ezikhulayo zokulawula zenza ukukhishwa kwamanzi oketshezi kungabi semthethweni noma kungabizi kahle. Ukusetshenziswa kwamandla kungaba kukhulu, ngakho imiklamo yanamuhla isebenzisa ukucindezela kwemvula ngomshini (mechanical vapor recompression) kanye nokubuyisela ukushisa okulahlekile ukuze kwehliswe izindleko zokusebenza. I-ZLD eklanywe kahle ingabuyisela cishe amaphesenti angu-90 amanzi angenayo futhi ivele ikhiqize imali engenayo emikhiqizweni etholakala kabusha.

I-China iphoqelela amazinga aqinile, aqondene nomkhakha othile ngaphansi koMthetho Wezokuvikelwa Kwemvelo obuyekeziwe, okuhlanganisa ukukhishwa komoya namanzi, ukuphathwa kwemfucuza eqinile, kanye nezibopho zokuqapha okuqhubekayo. Abakhiqizi kumele bagcine amarekhodi anemininingwane, bafake ama-analyzer aku-inthanethi lapho kudingeka, futhi babike idatha ngokungafihli emahhovisi endawo ezokuvikelwa kwemvelo. Ukuhlolwa okungamemezelwe kanye nokuhlola okuphambanayo okususelwa kumasathelayithi kwenza ukwephula umthetho okucashile kube nzima futhi kube nengozi enkulu. Izijeziso zingahlanganisa izinhlawulo ezinkulu, ukuvalwa kwezikhungo, kanye nokubekwa icala kobugebengu kubaphathi abafihla ukungathobeli umthetho. Ukuhlaziywa kwegebe elikhokhelwayo ngokumelene namazinga akamuva kakhulu kuyisinyathelo sokuqala esiya ohlelweni lokuthobela umthetho oluvikelekile.

Abakhiqizi banganciphisa ukukhishwa kwe-VOC kuqala ngokufaka esikhundleni sezinto ezingavuthiwe ezinamakhemikhali amaningi ngezinye ezingenamanzi noma ezinama-VOC aphansi, bese bethuthukisa ikhono lokubamba okuzungezile imishini yokucubungula. Ngokukhishwa okusele, ubuchwepheshe bokucekela phansi obufana nama-regenerative thermal oxidizers noma ama-catalytic oxidizers bunikeza ukulawula okuphumelelayo, kuyilapho imifudlana enokugxila okuphezulu ingase ifune izinhlelo zokubuyisela ama-solvent ezibuyisa imali ngokusebenzisa izinto ezibuyisiwe. Ukuklanywa kahle kwe-hood nokugcinwa kwamapayipi kubalulekile ngoba ukubamba okungahambi kahle kucekela phansi ukusebenza kokwelashwa ngokungabonakali. Ukuqapha njalo kokucekelwa phansi kuqinisekisa ukuthi uhlelo luyaqhubeka nokuhlangabezana nemikhawulo yemvume. I-Haidi Environment isiza amakhasimende ukuba akhethe futhi athuthukise ubuchwepheshe obuhambisana ne-airflow yabo ethile kanye namaphrofayili okugxila.

Ukukhetha phakathi kwe-NF ne-RO kuncike kumazinga okungcola okuhlosiwe kanye nekhwalithi efiswayo yamanzi atholakala kabusha. I-Reverse osmosis isusa usawoti omningi oncibilikile kanye nama-molecule amancane aphilayo, okwenza ifanelekele ukukhiqiza i-permeate ehlanzekile kakhulu yokondla amabhoyela noma izinyathelo ezibucayi zokukhiqiza. I-Nanofiltration ikhetha ngokukhethekile ukususa ama-ion ane-valence emibili njengobulukhuni nezinsimbi eziningi kuyilapho ivumela amanye ama-ion ane-valence eyodwa ukuba adlule, okufanelekele izinhlelo zokuthambisa nokunciphisa usawoti ngokwengxenye. Ubuningi bukasawoti emanzini, ukuthambekela kokwakheka kwamaketanga, kanye nezidingo zekhwalithi yamanzi ezansi konke kuba nomthelela ekukhetheni kokugcina. Imithombo yamanzi olwandle namanzi anosawoti omncane nayo idinga ama-membrane akhethekile anamazinga ahlukene okucindezela. Ukuhlolwa kwe-pilot ngamanzi angempela endawo kuyindlela ethembekile kakhulu yokuqinisekisa ukusebenza ngaphambi kokuzibophezela ohlelweni oluphelele.

I-Haidi Environment isekela ukuthuthukiswa kwekhwalithi yomoya ngokuhlola kobuchwepheshe, ukuhlela imithombo yokukhishwa kwezinto, ukukhetha kohlelo lokulawula i-VOC, kanye nemizamo yokubambisana nohulumeni basekhaya neziqhingi zezimboni. Onjiniyela bethu benza ukuhlola endaweni ukuze bathole amathuba okunciphisa umthelela omkhulu futhi balingise ukusabalala kokukhishwa ukuze baq Прioritize izenzo. Sisiza izikhungo ukuthi zisebenzise ukuqapha okuqhubekayo futhi zibonise ukuphumelela kwezilawuli zazo. Esifundeni sase-Tianjin sibambisene nohulumeni bezifunda emaphrojekthini okuthuthukisa umoya wezemvelo. Izinkampani ezifuna usizo olunjalo zingaxhumana nathi ukuze zithole ukubonisana okuyimfihlo okuhambisana nomkhakha wazo nophrofayela wesikhungo sazo.

Izinhlelo zokulawula amanzi ezihlakaniphile zisebenzisa izinzwa eziku-inthanethi, amapulatifomu okufaka amakhemikhali ngokuzenzakalelayo, kanye nokuhlaziywa kwedatha ukuze kufakwe amakhemikhali okwelapha kuphela lapho kudingeka khona nangesikhathi esifanele. Lokhu kunemba kugwema ukumosheka nokushintshashintsha kokusebenza kokufakwa ngesandla kuyilapho kuvimbela ukwakheka kwe-scale, ukugqwala, kanye nokungcola kwe-microbiological emijikelezweni yamanzi okupholisa. Ukuncishiswa kokusetshenziswa kwamakhemikhali kanye nesidingo esiphansi samandla kunciphisa ngokuqondile izindleko zokusebenza zanyanga zonke. Ukuqapha okusebenzayo kuphinde kwandise impilo yempahla ebizayo efana nama-heat exchanger nezinhlelo ze-membrane ngokuthola izinkinga kusenesikhathi. Umkhiqizo we-Haidi Environment i-Hydro-Intellect ubonisa le ndlela yokufaka ngobuhlakani yokuphathwa kwamanzi ezimbonini.

Qala ngokuhlola okuyisisekelo okubhala phansi ukukhishwa kwamanzi, ukulahlwa kwemfucuza, ukuphathwa kwemfucuza, ukusetshenziswa kwamakhemikhali, nezimvume ngokuya ngezidingo zendawo nezikazwelonke ezisebenzayo. Beka phambili izenzo zokulungisa ngokwezinga lobungozi, ubhekane nezinkinga ezingadala ukuvalwa ngokushesha noma inhlawulo ngaphambi kokutshalwa kwezimali okubanzi kokusimama. Sungula izinqubo ezicacile zokugcina amarekhodi, ukuqeqesha, nokuhlola kwangaphakathi ukuze ufake ukuthobela imithetho emisebenzini yansuku zonke. Hlanganyela nozakwethu abaqeqeshiwe bezemvelo ukuze bagcwalise izikhala zobuchwepheshe futhi baqinisekise indlela yakho ngokuhlolwa kwenkampani yezinkampani zangaphandle. Bese ubeka imigomo elinganisekayo futhi ubike inqubekelaphambili kubabambiqhaza ukuze wakhe ukwethenjwa okuhlala njalo.
