Ubunkimbinkimbi bezingxenye zamanzi angcolile kamasipala bugqame kakhulu. Amafutha aphathwa ngamanzi angcolile azokwakha i-milky turbidity, igwebu elikhiqizwe izinto zokuhlanza lizovela luhlaza okwesibhakabhaka-luhlaza, kanti i-leachate kadoti ivame ukuba nsundu ngokumnyama. Le sistimu exutshwe ngemibala eminingi ibeka izidingo eziphezulu amanzi angcolile decolorizers: idinga ukuba nemisebenzi eminingi efana ne-demulsification, ukukhipha amagwebu kanye nokunciphisa i-oxidation ngesikhathi esisodwa. Umbiko wokuhlola wesikhungo sokuhlanza indle e-Nanjing ubonisa ukuthi uhla lokuguquguquka kwe-chromaticity lwethonya lalo lungafinyelela kuma-degree angu-50-300, futhi i-chromaticity yokulahlwa kwamanzi angcolile aphathwa ama-decolorizers amanzi angcolile kusenzima ukuzinza ngaphansi kwama-degree angu-30.
Ama-decolorizers wamanje wamanzi angcolile bathole ukweqa kokusebenza ngomklamo wesakhiwo samangqamuzana. Uma sithatha i-polymer eguquliwe ye-dicyandiamide-formaldehyde njengesibonelo, amaqembu e-amine ne-hydroxyl kuketango lamangqamuzana alo enza umphumela wokusebenzisana: iqembu le-amine lithwebula odayi be-anionic ngesenzo se-electrostatic, futhi iqembu le-hydroxyl lichela ngama-ion ensimbi ukuze kuqedwe umbala wensimbi. Idatha yangempela yohlelo lokusebenza ibonisa ukuthi izinga lokususwa kwe-chromaticity yamanzi angcolile kamasipala lenyuke lafinyelela ngaphezu kwama-92%, futhi izinga le-alum flake sedimentation rate lenyuke cishe ngama-25%. Okuphawuleka kakhulu ukuthi le decolorizer yamanzi angcolile isengakwazi ukugcina umsebenzi ophezulu ngaphansi kwezimo eziphansi zokushisa.
Ngokombono walo lonke uhlelo lokuhlanza amanzi, i-wastewater decolorizer entsha iletha ukuthuthukiswa okuningi. Ngokuphathelene nokusebenza kahle kokwelashwa, ngemva kokuba isitshalo samanzi esibuyiselwe samukele i-decolorizer ehlanganisiwe yamanzi angcolile, isikhathi sokugcinwa kwe-tank yokuxuba okusheshayo sifinyezwe kusuka kumaminithi angu-3 kuya kumasekhondi angu-90; ngokwezindleko zokusebenza, izindleko zamakhemikhali ngethani lamanzi zehliswa cishe ngo-18%, futhi ukuphuma kodaka kwehliswe ngo-15%; mayelana nobungane bemvelo, okuqukethwe kwayo okusele kwe-monomer kwakulawulwa ngaphansi kuka-0.1 mg/L, okungaphansi kakhulu kwezinga lemboni. Ikakhulukazi lapho welapha indle ehlanganisiwe yenethiwekhi yendle, inomthamo omuhle wokubhafa wokushaqeka okungazelelwe kwe-chromatic okubangelwa ukukhukhulwa yimvula enkulu.
Ucwaningo lwamanje lugxile ezindleleni ezintathu ezintsha: ama-photocatalytic wastewater decolorizer angakwazi ukuzilimaza ngokwawo ngemva kokwelashwa ukuze agweme ukungcoliswa kwesibili; ama-decolorizers amanzi angcolile asabela ekushiseni angakwazi ukulungisa ngokuzenzakalelayo ukwakheka kwamangqamuzana ngokuya ngokushisa kwamanzi; kanye nokuthuthukiswa kwe-bioamanzi angcolile decolorizers hlanganisa amandla okuwohloka kwe-microbial. Lezi zindlela ezintsha ziyaqhubeka nokuqhubekisela phambili ukuhlanzwa kwamanzi angcolile kamasipala kubheke endleleni esebenza kahle neluhlaza.
