Ngokuthuthuka okusheshayo kwezimboni kanye nokukhula kwamadolobha, amanzi angcolile agcwele kakhulu aseyinkinga enkulu emvelweni. Amanzi angcolile agcwele kakhulu awagcini nje ngokuqukethe inani elikhulu lezinto eziphilayo, izinto ezingaphili, izinsimbi ezisindayo nezinye izinto eziyingozi, kodwa futhi nokugcwala kwawo kungaphezu kakhulu komklamo kanye namandla okwelapha ezindawo zokwelashwa kwamanzi angcolile ezivamile. Ngakho-ke, ukugcwala okuphezulu kokwelashwa kwamanzi angcolile kanye nokukhishwa okujwayelekile kubaluleke kakhulu.
1. Incazelo kanye nezici zamanzi angcolile agcwele ukugxila okukhulu Ukugxila okuphezulu kwamanzi angcolile, ngokuvamile kubhekisela emanzini angcolile aqukethe ukugxila okuphezulu kwezinto eziphilayo, izinsimbi ezisindayo, izinto ezinobuthi nezilimazayo kanye nezinye izinto ezingcolisayo. Okuqukethwe kokungcola emanzini angcolile kudlula kakhulu amanzi angcolile ajwayelekile, futhi kunzima ukukwelapha. Kungaqukatha izinhlobo ezahlukene zokungcola, njengezinto eziphilayo, izinsimbi ezisindayo, izinto ezinemisebe, njll. Okunye ukungcola kungaba nemiphumela yokuvimbela kuma-microorganisms futhi kuthinte umphumela wokwelashwa kwezinto eziphilayo, okunzima ukuwususa ngezindlela zokwelapha zebhayoloji ezivamile.
2. Isimo sokwenziwa kwamanzi amdaka agcwele kakhulu Ukukhiqizwa kwamakhemikhali: amanzi amdaka akhiqizwa enkambisweni yokukhiqizwa kwamakhemikhali avame ukuqukatha inani elikhulu lezinto eziphilayo, izinsimbi ezisindayo kanye nezinye izinto ezingcolisayo. Imboni yezemithi: amanzi amdaka emithi ngokuvamile aqukethe inani elikhulu lezinto eziphilayo, ama-antibiotic, njll., okunzima ukuwelapha. Imboni yedayi kanye nendwangu: amanzi amdaka akhiqizwa yilezi zimboni avame ukuqukatha inani elikhulu lezinto eziphilayo ezibolayo kanye ne-chromaticity. Ukufakwa kwe-Electroplating kanye ne-metallurgy: Amanzi amdaka aqukethe izinsimbi ezisindayo nezinto ezinobuthi akhiqizwa ngesikhathi sokufakwa kwe-electroplating kanye ne-metallurgy.
3. Ubuchwepheshe obuyinhloko bemishini yokwelapha amanzi amdaka agxilile kakhulu Imishini yokwelapha amanzi amdaka agxilile kakhulu, ngokuvamile ngokusebenzisa izindlela zomzimba noma zamakhemikhali ukususa izinhlayiya ezinkulu, izinto ezilengisiwe emanzini amdaka, ukudala izimo zokwelashwa okulandelayo. Izosebenzisa futhi ubuchwepheshe obuthuthukisiwe be-oxidation njenge-Fenton oxidation, i-ozone oxidation, ngokukhiqizwa kwe-oxidant enamandla ukuguqula izinto eziphilayo ezingaphikisi zibe izinto ezibola kalula. Sebenzisa isenzo se-metabolic sama-microorganisms ukususa izinto eziphilayo emanzini amdaka. Kumanzi amdaka agxilile kakhulu, izinqubo ezihlanganisiwe ze-anaerobic kanye ne-aerobic zingasetshenziswa ukuthuthukisa umphumela wokwelapha. Izinto ezinyakazayo emanzini amdaka nazo zingasuswa ngezindlela ezibonakalayo ngokusebenzisa ubuchwepheshe bokuhlukanisa i-membrane njenge-ultrafiltration kanye ne-reverse osmosis. Ngokusebenzisa i-chemical precipitation, i-ion exchange, i-adsorption kanye nobunye ubuchwepheshe bokwelapha insimbi esindayo, obusetshenziswa ukususa ama-ion ensimbi esindayo emanzini amdaka. Ngakho-ke, ngemishini yokwelapha indle egxilile kakhulu, kubaluleke kakhulu ukuqinisekisa ukuthi ukungcola kufinyelela ezingeni elifanele, ukhethe inqubo yokwelapha ngokufanele, ulawule ngokuqinile inqubo yokwelapha, uqinise ukwelashwa kwangaphambi kokwelashwa, wenze ngcono amapharamitha okusebenza kanye nokutholwa nokuhlolwa okuvamile. Uma kutholakala izinkinga, thatha izinyathelo ezisheshayo ukuze uzilungise.
Ngenxa yokubaluleka kwekhwalithi yamanzi ayo, ukwelashwa kwamanzi amdaka anezinga eliphezulu kunezidingo zobuchwepheshe eziqinile zemishini. Kudingeka ibe nobuchwepheshe obuhle bomkhiqizo, ulwazi lwephrojekthi, kanye nomqondo wokulungisa izinyathelo ezimweni zendawo ukuqinisekisa ukuthi ukungcola kwemishini yokwelapha amanzi amdaka anezinga eliphezulu kuyahlangabezana nezindinganiso. Ukuvikelwa kwemvelo kweJiading kuyifektri ephezulu embonini yokwelapha indle iminyaka eyishumi, esesifundazweni saseJiangsu, imisebe ezweni lonke, ebhekene namazwe aphesheya kwezilwandle, inethimba eliqinile lokulawula ikhwalithi yobuchwepheshe bomkhiqizo.
