Kunezindlela ezintathu eziyinhloko:
1. Indlela yamakhemikhali
Kalula nje, kusho ukufaka amakhemikhali emanzini angcolile ukuze ukungcola okungaphakathi kukwazi ukusabela futhi kususwe kalula.
Indlela yokujiya：TUmgomo osebenzayo wendlela yokujiya ukwengeza izinto zamakhemikhali emanzini, okubangela ukuthi izinhlayiya ezincane ezilengisiwe zihlangane futhi zakhe ama-floc amakhulu, bese zihlala phansi ngamandla adonsela phansi. Le ndlela ingasusa ngempumelelo i-chromaticity, amabhaktheriya, kanye nezinye izinto eziphilayo emanzini. Kodwa-ke, umphumela wayo wokwelapha ezintweni ezincibilikiswe ngokuphelele emanzini ulinganiselwe, futhi umphumela wokwelapha uthintwa kalula ukuguquguquka kokushisa kwamanzi kanye nenani le-pH.
Indlela yokuxubha:UAma-oxidant (njenge-chlorine, i-ozone) ukuze abole izinto ezinobuthi zibe yizinto ezingenangozi. I-Ozone inemiphumela emihle futhi ayinayo ingcoliso yesibili, kodwa izindleko ziphezulu; I-Chlorine ivame ukusetshenziswa futhi ifanelekela ukwelapha amanzi angcolile aqukethe i-phenol ne-cyanide; Umphumela we-oxidation yomoya mubi kancane futhi ngokuvamile usetshenziswa emanzini angcolile lapho ungcolisi lufakwa khona kalula.
Indlela ye-Electrochemical: Ugesi usetshenziswa ukuvumela ukungcola ukuthi kusebenze ebusweni be-electrode ukuze kususwe, futhi ngezinye izikhathi i-sodium chloride iyengezwa ukuthuthukisa umphumela. Le ndlela inomphumela omuhle wokucubungula, kodwa nokubi kwayo nakho kusobala: ngakolunye uhlangothi, idla ugesi omningi futhi inezindleko eziphezulu zokusebenza; Ngakolunye uhlangothi, ezinye izimpendulo ezingemuhle zingase zenzeke ngesikhathi senqubo, okuholela ekungcoleni kwesibili.
2. Indlela Yomzimba
Hlukanisa ukungcola okuqinile emanzini ngezindlela ezibonakalayo.
Indlela yokuhlunga isebenzisa imidiya yokuhlunga enezimbobo ezincane (njengezihlungi ezincane) ukuze ibambe izinto eziqinile ezilenga emanzini.
Umthetho wokufaka inhlabathi emanzini ukusebenzisa amandla adonsela phansi ukuze kuvunyelwe izinhlayiya ezisindayo ezilenga emanzini angcolile ukuthi zihlale phansi emanzini ngokwemvelo.
Indlela yokuntanta emoyeni ifaka inani elikhulu lamabhamuza amancane emanzini, okubangela ukuthi anamathele ezinhlayiyeni ezingcolile futhi akhe umzimba ontantayo onobuningi obuphansi kunamanzi. Bese ukhuphukela emanzini ngokuntanta bese ususwa ngemishini yokuklwebha.
Lezi zindlela zilula futhi kulula ukuzilawula, kodwa azikwazi ukususa ukungcola okuncibilikisiwe emanzini futhi zinemikhawulo ekusetshenzisweni kwazo.
3. Ubuchwepheshe be-Photocatalytic oxidation
Ngokusebenzisa ukukhanya kwe-ultraviolet kanye nama-oxidizing agents (njenge-hydrogen peroxide), ukungcola okunzima ukukubola (njenge-polychlorinated biphenyls) kungabhujiswa ngokuphelele.
Kukhona indlela ebizwa ngokuthi 'i-photocatalytic Fenton', engakhiqiza ngokushesha inani elikhulu lezinto ezisebenzayo futhi ibolise ngempumelelo izinto eziphilayo ngaphansi kwesenzo esihlangene sama-ion okukhanya nensimbi.
Enye indlela ukwengeza izinto ze-semiconductor ezizwela ukukhanya (njenge-titanium dioxide), ezikhiqiza ama-free radical akhipha i-oxidation ephezulu ngaphansi kokukhanya okukhanyayo, okuqeda ngokuphelele ukungcola kube izinto ezingenangozi njenge-carbon dioxide namanzi. Le ndlela inamandla amakhulu okwelapha ukungcola okungenakulinganiswa.
