Okokuqala, indlela yokwelashwa kwendle ikakhulukazi kubandakanya ukwelashwa ngokomzimba kanye nokwelashwa kwamakhemikhali. Indlela Yomzimba ukusebenzisa izinto zokuhlunga ezahlukahlukene ezinosayizi ohlukile we-pore, ukusetshenziswa kwezindlela ezivinjelwe noma ukungcola emanzini kukhishwe ngaphandle kwe-adbonption, ukuze kudlule ivolumu elikhudlwana lingelona iqiniso, bese lithola amanzi ahlanzekile. Ngaphezu kwalokho, indlela ebonakalayo ifaka nendlela yemvula, okuwukuvumela ukungcola ngengxenye encane yokugcwala kwamanzi ukuze idonsele phezulu, noma ukungcola okulingana nengxenye enkulu efinyelela ngaphansi kobuso, bese uthola. Indlela yamakhemikhali ukusebenzisa amakhemikhali ahlukahlukene ukuguqula ukungcola emanzini kube yizinto eziyingozi ezingenabungozi emzimbeni womuntu, ngemuva kokuqoqwa ukungcola emanzini, ivolumu liba likhulu, ungasebenzisa indlela yokuhlunga ukuze ususe ukungcola.
I-calcium chloride, ikhemikhali elivame ukusetshenziswa ekwelashweni kwendle, liyindawo yokufaka i-inorganic okuyi-chlorine ne-calcium, i-halide ejwayelekile ye-ionic. I-Chloride ion ingabulala amanzi, lala amagciwane ayingozi, futhi anciphise ubuthi bamanzi. I-calcium ion ingathatha indawo yezensimbi yensimbi equkethwe emanzini, ihlukanise futhi ikhiphe ngaphandle kwe-ion esindayo yensimbi, futhi isuse i-calcium ion yezulu, enesibulalambiso esihle nemiphumela yokuhlanza.
Okulandelayo ukwethula iqhaza elithile le-calcium chloride ekwelashweni kwendle kwendle:
1. I-calcium chloride incibilika emanzini ngemuva kokuthi i-chloride ion inomphumela wokubulawa inzalo.
2 Ukuze sinciphise ukulimala kwezinto ezinobuthi kakhulu zezindawo zensimbi eziya engxenyeni ye-biochemical, i-calcium chloride isetshenziswa kwinqubo yokuhlehlisa ukuze ususe lezi zinto ezinobuthi futhi eziyingozi, ezidlala indima ebalulekile. Uma le nto isetshenziswa esigabeni se-effluent, i-chloride ion idlala indima ye-bactericide. I-calcium ion yasungulwa i-calcium hydroxide yanezela futhi yasuswa yizinkutha.
3. I-PH yokungathathi hlangothi kanye nokulawulwa kwangaphambi kokulawulwa kwe-acid sexpage reate ukunweba impilo yenethiwekhi yenethiwekhi yepayipi.
Inqubo ethile yesicelo: Ngemuva kokuthi amanzi angcolile aqoqwa ethangi lokulawula, amanzi angcolile aphakanyiselwa ethangini lokuhlangana ngepompo yokuphakamisa. Ithangi lokuhlangana lihlukaniswe izinqubo ezimbili zokuxuba kancane nokuxuba okusheshayo, ingqikithi yezigaba ezine zokuphendula. Ethangini lokuxuba elisheshayo, i-sodium hydroxide ingezwe kwipompo ye-dosing ukuze ulungise i-PH yamanzi ahlanganisiwe ethangini kuya ku-8, futhi i-polyaluminum chloride ye-polyaluminum ne-calcium chloride yengezwa ngasikhathi sinye. Ngokungeza i-polylacrylamide ye-flocculant ethangini elihamba kancane, izinhlayiya ezihleliwe ze-calcium chloride zihlangana nomunye nomunye ukwakha i-floc enkulu ye-granular; Ngemuva kokugcwala, i-effluent igeleza ungene ethangini le-sedimentation, ngokuthola indawo yemvelo ukufeza inhloso yokwehlukaniswa okuqinile okuwuketshezi, i-supernatarate igcwele engxenyeni engenhla yethangi ledimentation, bese igeleza yaba yimvula yezinwele zesibili. Ngemuva kokwelashwa kwamasekondari kanye nokwelashwa kwemvula, amanzi adlula esikhwameni sesikhwama futhi asebenze ngesihlungi sekhabhoni echibini lomnikazi ngemuva kokuthola ukutholwa kwe-fluoride ion ngemuva kokudlula kokutholwa kwe-fluoride ama-ion, bese ivelu ye-PH iguqulwe futhi ikhishwe. Amanzi angafaneleki akhishwa ethangini elinezimo bese elashwa.
