Ukwelashwa kwamanzi ezimboni ze-zero ukukhishwa kwamanzi ezimboni kuyinhloso ebalulekile emkhakheni wokuvikelwa kwemvelo, ngezindlela zobuchwepheshe zokuthola ukwelashwa okusebenzayo kwamanzi amdaka kanye nokusetshenziswa kwezinsiza, ukuvikela ukungcoliswa kwemvelo, ukuvikelwa kwezinsizakusebenza zamanzi kubaluleke kakhulu. Ngizokwethula izindlela eziningi ezinkulu ze-wartewater yokwelashwa kwe-zero technology zero.
Okokuqala, ubuchwepheshe bokwelashwa ngokomzimba bungenye yezindlela ezibalulekile zokuthola ukwelashwa kwamanzi ezimboni ze-zero. Phakathi kwazo, ubuchwepheshe bokuhlukaniswa kweMembrane buyindlela esebenza kahle yokopha ngokomzimba kanye namandla. Ngokusebenzisa izinto ze-membrane ezinosayizi ohlukile we-pore, izinto eziyingozi nama-ion esindayo e-wastewater ahlukaniswe ngempumelelo ukufeza inhloso yokuhlanzwa kwamanzi. Ubuchwepheshe be-Filtration be-Membrane-membrane, okungukuthi inqubo yokuhlanganisa ulwelwesi lwe-ultrafiltration kanye ne-reverse osmosis membrane, kungenye yezicelo ezibalulekile ze-membrane degration technology. Lobu buchwepheshe bungafezekisa izihlungi eziningi ezijulile zamanzi amdaka, ususe izakhi eziyingozi, futhi uvuselelwa ngokunembile u-Wastewater ukuze uzuze ukukhipha.
Okwesibili, ubuchwepheshe bokwelashwa ngamakhemikhali buyindlela ebalulekile yokuthola ukwelashwa kwamanzi wezimboni ze-zero. Ubuchwepheshe be-Redox buguqula ukungcoliswa kwamanzi okungcoliswa kwamanzi angcolile kube yizinto ezingezona zobungozi futhi ezingenabungozi ngokusabela kwamakhemikhali, ngaleyo ndlela kufinyelele ekwelapheni okujulile kwamanzi amdaka. Ubuchwepheshe obuthuthukisiwe be-oxidation, njenge-fenton oxidation kanye ne-oxidation ye-ozone, kungasusa ngempumelelo i-organic ture-to-biodegrade organic emanzini angcolile futhi uthuthukise i-biochemistry of wandchemis. Ngaphezu kwalokho, indlela yemvula yamakhemikhali, indlela yokushintshana kwamakhemikhali, njll. Baphinde basebenzise ubuchwepheshe bokwelashwa kwamakhemikhali bamakhemikhali, okungasusa ama-metal stus esindayo futhi kumiswe udaba lwamanzi amdaka.
Ubuchwepheshe bokwelashwa biological buyingxenye ebaluleke kakhulu ye-Zero Decialial Deleater ukwelashwa kwamanzi wezimboni. Ubuchwepheshe be-Biological Treatment Technology busebenzisa i-metabolism yama-microorganisms ukubola futhi uguqule izinto eziphilayo kumanzi amdaka. Ubuchwepheshe obujwayelekile bokuthola ukwelashwa bufaka phakathi i-sludge esetshenzisiwe, i-biofilm, nokugaya i-anaerobic. Lezi zibuchwepheshe zingasusa kahle ukungcoliswa kwe-organic emanzini angcolile, zinciphise i-biochemical oxygen funa (i-COD) ne-chemigen oxygen funa (i-cod) yamanzi amdaka, futhi athole ukuphathwa okungenabungozi kwamanzi amdaka.
Ngaphezu kwalezi zindlela ezingenhla zobuchwepheshe obungenhla, kukhona ubuchwepheshe obuqhakazi obuthola nendima ebalulekile ekukhiphekeni kwamanzi kwezimboni. Isibonelo, ubuchwepheshe be-crystallalliation Technology bufinyelela ukuhlukaniswa okuqinile okuwuketshezi wamanzi amdaka ngokuwukhipha emanzini angcolile ukuze usawoti ancibilike kuwo aqothule kulo msebenzi. Lobu buchwepheshe bususa kahle usawoti kanye nezinto eziyingozi ezivela emanzini angcolile futhi uzuze inhloso yokuphuma kwe-zero.
Ngaphezu kwalokho, ubuchwepheshe bokuvuselela izinsiza kuyisihluthulelo sokuthola ukuphuma kwe-zero ekwelashweni kwamanzi ezimboni. Ngokukhipha nokubuyisa izakhi eziwusizo kumanzi amdaka, hhayi nje kuphela ukuphuma kwamanzi okukhishwa kwamanzi, kodwa futhi nokuphindaphindeka kwezinsizakusebenza kungatholwa. Isibonelo, ama-ion anesisindo sensimbi kanye nodaba lwe-organic emanzi oludonswayo kungatholwa futhi kusetshenziswe ngezindlela ezithile zobuchwepheshe ukufeza ukusetshenziswa kwezingceme kwamanzi amdaka.
Ngamafuphi, kunezindlela ezahlukahlukene zobuchwepheshe zokwelapha amanzi amdaka ezimboni anokuphuma kwe-zero, kufaka phakathi ubuchwepheshe bokwelashwa ngokomzimba, ubuchwepheshe bokwelashwa ngamakhemikhali, ubuchwepheshe bokwelashwa kwemvelo kanye nobuchwepheshe bokuvuselela usizo. Ukusetshenziswa kwalezi zibuchwepheshe kudinga ukukhethwa futhi kwenziwe kahle ngokuya ngohlobo lwamanzi angcolile kanye nezidingo zokwelashwa, ukuze kufinyelelwe umgomo wokuphathwa kwamanzi okusebenza kahle, okulondolozwa kwamandla nemvelo nokukhishwa kwe-zero. Ngenqubekela phambili eqhubekayo kanye nokwenziwa okusha kwesayensi nezobuchwepheshe, kukholelwa ukuthi ngokuzayo kuzoba nezindlela ezithuthukile kakhulu kuzosetshenziswa endlebeni yokwelashwa kwamanzi ezimboni, ukukhuthaza imbangela yokuvikelwa kwezemvelo ezingeni eliphakeme.
