Wannan hanyar ita ce a haxa foda ko barbashi na abubuwa masu buguwa kamar carbon da aka kunna da yumbu da najasa, ko barin najasar ta wuce gadon tacewa wanda ya ƙunshi ɓangarorinsa, ta yadda gurɓatar da ke cikin najasa ta kasance ana ɗanɗaɗawa a saman abin da ya lalace ko kuma a tace shi.
Akwai nau'o'in adsorbents da yawa da ake amfani da su wajen maganin shaye-shaye, kuma ya kamata a yi la'akari da zaɓi na adsorbents zuwa rini a cikin aikin, kuma a zaɓi abubuwan da ake amfani da su daidai da ingancin najasa. Sakamakon ya nuna cewa a cikin rini da ruwan sha tare da pH = 12, yawan cirewar anion rini zai iya kaiwa 95% -100% ta amfani da silicon polymers (methyl oxygen) a matsayin adsorbent. Kaolin kuma adsorbent ne. Nazarin ya nuna cewa kaolin na iya yin tasiri yadda ya kamata ya shafa launin rawaya kai tsaye a cikin najasa ta hanyar dogon sarkar kwayoyin cation.
Magungunan sinadarai
An raba shi zuwa nau'ikan hanyar coagulation iri biyu da hanyar oxidation, waɗanda ke da tasirin su a cikin maganin ruwa.
Hanyar coagulation galibi ta haɗa da hanyar hazo coagulation da hanyar yawo da iskar gas. Yawancin coagulant da aka yi amfani da su galibi gishirin aluminium ne ko gishirin ƙarfe, daga cikinsu akwai mahimmin chloride na aluminium (PAC) yana da ingantaccen aikin talla, kuma ferrous sulfate yana da mafi ƙarancin farashi. Babban abũbuwan amfãni na coagulation Hanyar ne sauki tsari kwarara, m aiki da kuma management, m zuba jari a cikin kayan aiki, kasa yanki da high decolorization yadda ya dace ga hydrophobic dyes. Rashin lahani shine tsadar aiki mai yawa, laka mai yawa da bushewar ruwa mai wahala, da rashin kyawun magani na rini na hydrophilic.
Akwai hanyoyi da yawa na oxidation, kamar ozone oxidation da haske oxidation. Ozone hadawan abu da iskar shaka Hanyar iya samun mai kyau decolorization sakamako ga mafi yawan dyes, amma matalauta decolorization sakamako ga sulfur, raguwa, Paint da sauran insoluble dyes. Photooxidation jiyya na dyeing sharar gida decolorization yadda ya dace ne high, amma kayan aiki zuba jari da kuma amfani da wutar lantarki bukatar da za a kara rage, yin amfani da gida na wannan hanya ba da yawa Enterprises.
Electrolytic magani
Electrolysis yana da tasiri mai kyau a kan maganin rini na ruwa mai dauke da ruwan acid, adadin decolorization shine 50% ~ 70%, amma tasirin magani akan ruwa mai zurfi da launi mai zurfi da COD mara kyau.
An fahimci cewa ƙididdiga, kowane nau'in rini saboda nau'ikan kayan lantarki daban-daban a cikin maganin electrolytic na ƙimar cirewar COD ɗin su yana da babban bambanci, tsarin cirewar COD gabaɗaya: dyes sulfide, rini na VAT rini-acid, rini mai tsaka-tsakin tsaka-tsaki, rini-cationic kai tsaye.
