Kukho iindlela ezintathu eziphambili:
1. Indlela yekhemikhali
Ngamafutshane, kuthetha ukongeza iikhemikhali emanzini amdaka ukuze ukungcola okungaphakathi kusebenze kwaye kube lula ukukususa.
Indlela yokujiya：TUmgaqo osebenzayo wendlela yokujiya kukongeza iikhemikhali emanzini, nto leyo ebangela ukuba amasuntswana amancinci axhonyiweyo ahlangane aze enze ii-flocs ezinkulu, aze emva koko ahlale phantsi ngenxa yomxhuzulane. Le ndlela inokususa ngempumelelo i-chromaticity, iibhaktheriya, kunye nezinye izinto eziphilayo emanzini. Nangona kunjalo, isiphumo sayo sonyango kwizinto ezinyibilikiswe ngokupheleleyo emanzini silinganiselwe, kwaye isiphumo sonyango sichaphazeleka lula kukutshintshatshintsha kobushushu bamanzi kunye nexabiso le-pH.
Indlela yokuxutywa kwe-oxidation:Ui-single oxidants (ezifana ne-chlorine, i-ozone) ukuze ibole izinto ezinobuthi zibe zezo zingenabungozi. I-ozone inemiphumo emihle kwaye ayinangcoliseko lwesibini, kodwa ixabiso liphezulu; I-chlorine isetyenziswa rhoqo kwaye ifanelekile ukunyanga amanzi amdaka ane-phenol kunye ne-cyanide; Isiphumo se-oxidation yomoya asilunganga kwaye sisetyenziswa ngokubanzi emanzini amdaka apho ungcoliseko lufakwa lula kwi-oxidation.
Indlela ye-Electrochemical: Umbane usetyenziswa ukuvumela ukungcola ukuba kusebenze kumphezulu we-electrode ukuze kususwe, kwaye ngamanye amaxesha i-sodium chloride iyongezwa ukuphucula isiphumo. Le ndlela inesiphumo esihle sokucubungula, kodwa iingxaki zayo nazo ziyabonakala: kwelinye icala, idla umbane omninzi kwaye ineendleko eziphezulu zokusebenza; Kwelinye icala, ezinye iimpendulo ezingalindelekanga zinokwenzeka ngexesha lenkqubo, nto leyo ekhokelela kungcoliseko lwesibini.
2. Indlela Yomzimba
Yahlula ukungcola okuqinileyo emanzini ngeendlela ezibonakalayo.
Indlela yokucoca isebenzisa imidiya yokucoca ene-micropores (ezifana nezihluzi ezine-microporous) ukuze ibambe izinto eziqinileyo ezixhonyiweyo emanzini.
Umthetho wokwenziwa kwenkunkuma kukusebenzisa amandla angaphantsi komhlaba ukuvumela amasuntswana anzima axhonyiweyo kwilindle ukuba ahlale ngokwemvelo ezantsi kwamanzi.
Indlela yokubhabha emoyeni ingenisa inani elikhulu lamaqamza amancinci emanzini, nto leyo ebangela ukuba anamathele kumaqhekeza angcolileyo aze enze umzimba odadayo onobunzima obuphantsi kunamanzi. Emva koko unyuka uye kumphezulu wamanzi ngokubhabha kwaye ususwe ngezixhobo zokukrwela.
Ezi ndlela zilula kwaye kulula ukuzilawula, kodwa azinakususa ungcoliseko olunyibilikiswe emanzini kwaye zinemida ekusetyenzisweni kwazo.
3. Itekhnoloji ye-Photocatalytic oxidation
Ngokusebenzisa ukukhanya kwe-ultraviolet kunye nee-oxidizing agents (ezifana ne-hydrogen peroxide), izinto ezingcolisayo ezinzima ukubola (ezifana ne-polychlorinated biphenyls) zinokutshatyalaliswa ngokupheleleyo.
Kukho indlela ebizwa ngokuba yi-'photocatalytic Fenton', enokuvelisa ngokukhawuleza inani elikhulu lezinto ezisebenzayo kwaye ibolise ngokufanelekileyo izinto eziphilayo phantsi kwesenzo esidibeneyo se-ions zokukhanya kunye ne-iron.
Enye indlela kukongeza izinto ze-semiconductor ezisebenzisa ukukhanya (ezifana ne-titanium dioxide), ezivelisa ii-free radicals ezikhupha i-oxidation ephezulu phantsi kokukhanya, zibolisa ngokupheleleyo izinto ezingcolisayo zibe zizinto ezingenabungozi ezifana ne-carbon dioxide namanzi. Le ndlela inamandla amakhulu okunyanga izinto ezingcolisayo ezilahla i-calcitrant.
