Ubunzima bezingxenye zamanzi amdaka kamasipala bubonakala kakhulu. Amafutha athwalwa amanzi amdaka aphekwayo azokwakha ukungcola okufana nobisi, igwebu elikhiqizwa yizinsipho lizobonakala liluhlaza okwesibhakabhaka, kanti ukuvuza kwemfucuza kuvame ukuba nsundu ngokumnyama. Lolu hlelo oluxubile olunemibala eminingi lubeka izidingo eziphakeme ku izisusa umbala emanzini amdaka: idinga ukuba nemisebenzi eminingi efana nokususa i-mulsification, ukususa i-foam kanye nokunciphisa i-oxidation ngesikhathi esisodwa. Umbiko wokuhlolwa kwesitshalo sokwelapha indle eNanjing ukhombisa ukuthi ububanzi bokuguquguquka kwe-chromaticity yethonya layo bungafinyelela kuma-degree angu-50-300, futhi i-chromaticity yendle ehlungwe yizisusa-mbala zamanzi amdaka zendabuko kusenzima ukuzinzisa ngaphansi kwama-degree angu-30.
Izisusa-mbala zamanzi amdaka zanamuhla bafinyelele igxathu lokusebenza ngokuklama isakhiwo sama-molecule. Uma sibheka i-polymer eguquliwe ye-dicyandiamide-formaldehyde njengesibonelo, amaqembu e-amine kanye ne-hydroxyl ku-chain yayo yama-molecule akha umphumela wokubambisana: iqembu le-amine libamba amadayi e-anionic ngesenzo se-electrostatic, kanti iqembu le-hydroxyl lihlanganisa ama-ion ensimbi ukuze kuqedwe umbala wensimbi. Idatha yangempela yokusetshenziswa ikhombisa ukuthi izinga lokususwa kwe-chromaticity kwamanzi amdaka kamasipala lenyuke laya ngaphezu kwama-92%, kanti izinga lokusaphazeka kwe-alum flake lenyuke cishe ngama-25%. Okuphawuleka kakhulu ukuthi le-decolorizer yamanzi amdaka isengaqhubeka nomsebenzi ophezulu ngaphansi kwezimo zokushisa eziphansi.
Ngokombono wohlelo lonke lokwelapha amanzi, i-decolorizer entsha yamanzi amdaka iletha ukuthuthuka okuningi. Ngokuphathelene nokusebenza kahle kokwelashwa, ngemuva kokuba isitshalo samanzi esibuyiselwe sisebenzise i-composite water decolorizer, isikhathi sokugcina ithangi lokuxuba ngokushesha sancishiswa kusukela kumaminithi ama-3 kuya kumasekhondi angama-90; ngokwezindleko zokusebenza, izindleko zamakhemikhali ngethani lamanzi zancishiswa cishe ngo-18%, kanti umkhiqizo wodaka wehliswa ngo-15%; ngokwendawo enobungani nemvelo, okuqukethwe kwayo okusele kwe-monomer kwalawulwa ngaphansi kuka-0.1 mg/L, okungaphansi kakhulu kwezindinganiso zemboni. Ikakhulukazi lapho kwelashwa indle yenethiwekhi yendle ehlanganisiwe, inamandla amahle okuvimba ukushaqeka okungazelelwe kwe-chromatic okubangelwa ukukhuhla kwemvula enkulu.
Ucwaningo lwamanje lugxile ezindleleni ezintathu ezintsha: ama-decolorizer amanzi amdaka asebenzisa i-photocatalytic angazilimaza ngokwawo ngemva kokwelashwa ukuze agweme ukungcola kwesibili; ama-decolorizer amanzi amdaka aphendula ngokushisa angalungisa ngokuzenzakalelayo ukwakheka kwama-molecule ngokuya ngokushisa kwamanzi; kanye nokuthuthukiswa kwe-bioizisusa umbala emanzini amdaka ukuhlanganisa amakhono okucekela phansi amagciwane. Lokhu kusungulwa kuyaqhubeka nokuqhuba ukwelashwa kwamanzi amdaka kamasipala kuya endleleni esebenza kahle futhi enempilo.
