Ubunzima bezinto zamanzi amdaka kamasipala bubonakala kakhulu. Igrisi ethwalwa ngamanzi amdaka okupheka iya kwenza i-turbidity efana nobisi, i-foam eveliswa ziisepha iya kubonakala iluhlaza okwesibhakabhaka, kwaye ukuvuza kwenkunkuma kudla ngokuba mdaka omnyama. Le nkqubo ixutyiweyo enemibala emininzi inika iimfuno eziphezulu izinto zokususa umbala emanzini amdaka: kufuneka ibe nemisebenzi emininzi efana nokususa i-mulsification, ukususa i-foaming kunye nokunciphisa i-oxidation ngaxeshanye. Ingxelo yovavanyo lwesityalo sokunyanga amanzi amdaka eNanjing ibonisa ukuba uluhlu lokuguquguquka kwe-chromaticity yempembelelo yaso lunokufikelela kwi-50-300 degrees, kwaye i-chromaticity ye-lindle ecociweyo zii-decolorizers zemveli zamanzi amdaka kusenzima ukuzinzisa ngaphantsi kwe-30 degrees.
Izixhobo zokususa imibala zamanzi amdaka zanamhlanje bafikelele kwinqanaba eliphezulu lokusebenza ngoyilo lwesakhiwo semolekyuli. Ukuthatha i-polymer eguquliweyo ye-dicyandiamide-formaldehyde njengomzekelo, amaqela e-amine kunye ne-hydroxyl kwi-molecular chain yayo enza isiphumo se-synergistic: iqela le-amine libamba iidayi ze-anionic ngesenzo se-electrostatic, kwaye iqela le-hydroxyl lixuba ngee-ion zesinyithi ukuze kususwe umbala wesinyithi. Idatha yokwenyani yesicelo ibonisa ukuba izinga lokususwa kwe-chromaticity yamanzi amdaka kamasipala linyuke laya ngaphezulu kwe-92%, kwaye izinga lokutsalwa kwe-alum flake linyuke malunga ne-25%. Okuphawulekayo ngakumbi kukuba le nkunkuma yokususa umbala isenokugcina umsebenzi ophezulu phantsi kweemeko zobushushu obuphantsi.
Ngokwembono yenkqubo yonke yokucoca amanzi, isixhobo esitsha sokususa umbala emanzini amdaka sizisa uphuculo oluninzi. Ngokuphathelele ukusebenza kakuhle konyango, emva kokuba isityalo samanzi esibuyiselweyo sisebenzise isixhobo sokususa umbala emanzini amdaka esidityanisiweyo, ixesha lokugcina itanki yokuxuba ngokukhawuleza lancitshiswa ukusuka kwimizuzu emi-3 ukuya kwimizuzwana engama-90; ngokweendleko zokusebenza, iindleko zeekhemikhali ngetoni nganye yamanzi zancitshiswa malunga ne-18%, kwaye imveliso yodaka yancitshiswa nge-15%; ngokwemeko-bume, umxholo wayo we-monomer oseleyo walawulwa ngaphantsi kwe-0.1 mg/L, engaphantsi kakhulu komgangatho weshishini. Ingakumbi xa kunyangwa amanzi amdaka adibeneyo, inomthamo olungileyo wokukhusela ukutshatyalaliswa ngequbuliso kwe-chromatic okubangelwa kukukhuhla kwemvula enkulu.
Uphando lwangoku lugxile kwiindlela ezintathu ezintsha: izixhobo zokususa umbala emanzini amdaka ezisebenzisa i-photocatalytic zinokuzitshabalalisa ngokwazo emva konyango ukuze kuthintelwe ungcoliseko lwesibini; izixhobo zokususa umbala emanzini amdaka ezisabela kubushushu zinokulungisa ngokuzenzekelayo ukwakheka kweemolekyuli ngokweqondo lobushushu bamanzi; kunye nezinto eziphuculweyo ngebhayoloji.izinto zokususa umbala emanzini amdaka ukudibanisa amandla okubola kweentsholongwane. Ezi zinto zintsha ziyaqhubeka nokuqhuba unyango lwamanzi amdaka kamasipala ukuya kwicala elisebenzayo neliluhlaza ngakumbi.
