Amanzi angcolile wokudaya akhiqizwa umshini wendwangu angcolisa kakhulu imvelo. Ngakho-ke, amanzi angcolile adinga ukwelashwa ngaphambi kokuba akhishwe noma asebenze kabusha. I-ozone iyi-oxidant enamandla ngokweqile futhi idlala indima ebalulekile ekwelapheni amanzi angcolile.
Ukuphrinta nokudaya amanzi angcolile kungamanzi angcolile ezimboni ane-chroma enkulu, okuqukethwe okuphezulu okuphilayo nokwakheka okuyinkimbinkimbi. Amanzi aqukethe nenqwaba yodayi abasalile, i-alkalis, i-diazo, i-azo, njll, okunzima ukuphatha. Amanzi angcolile endwangu avame ukuphathwa ngezigaba ezintathu:
Okokuqala: ukwelashwa ngokomzimba, okuhlukaniswe yinzika nokuhlungwa kwegridi;
Okwesibili: ukwelashwa ngamakhemikhali, ukwengeza amakhemikhali okwenza ngcono ikhwalithi yamanzi;
Okwesithathu: ukwelashwa okuthuthukile, kusetshenziswa ubuchwepheshe be-ozone oxidation , ukunciphisa ngempumelelo i-COD, amanani we-BOD, nokwenza ngcono kakhulu ukusetshenziswa kabusha kwamanzi noma ukuhambisana.
Indlela yesicelo se-ozone:
I-ozone iyi-oxidant enamandla, futhi umthamo wayo we-redox emanzini ungowesibili kuphela ku-fluorine. Ijwayele ukusetshenziselwa ukwelashwa kwangaphambili nokwelashwa okuthuthukile kwamanzi angcolile ezimboni. Inemisebenzi eminingi ekwelashweni kwamanzi, inzalo, ukukhipha amakholomu, ukukhipha isisu, ukukhipha isisu kanye nokubola kwe-oxidative. I-Ozone isetshenziselwa ikakhulukazi ukuguqula umbala nokucekela phansi izinto eziphilayo futhi yehlise amanani we-COD neBOD ekwelapheni ukuphrinta nokudaya amanzi angcolile.
Ekusebenzelaneni ne-chromaticity yokuphrinta nokudaya amanzi angcolile, i-ozone oxidation ingaphula isibopho esidayisayo sedayi lokunikela ngopende noma i-chromogenic yedayi, futhi ngesikhathi esifanayo ibhubhise i-cyclic compound eyakha iqembu le-chromophore, ngaleyo ndlela inciphise amanzi angcolile.
I-ozone iphendula ngezinto ezilukhuni okwehliselwa phansi, eziguqula ubuthi bezinto ezingcolisayo kanye nokuwohloka kwamakhemikhali. Ngasikhathi sinye, nciphisa i-COD ne-BOD, uthuthukise ikhwalithi yamanzi. I-ozone ingakhiqiza uketshezi lwezinto eziphilayo kanye nezilwanyana ezincane emanzini angcolile, futhi yehlise amanani ayo we-COD ne-BOD ngaphandle kokungcola kwesibili nokubola okulula. Ngasikhathi sinye, ingakhipha futhi amakholomu, yenze inzalo futhi isuse iphunga emzimbeni. Isetshenziswe kabanzi ekwelapheni okuthuthukile kokuhlanzwa kwamanzi angcolile.
