Ob txoj kev siv tau zoo rau kev kho chromium electroplating wastewater

Ferrous sulfate thiab sodium bisulfite yog tam sim no cov kev coj ua rau kho hexavalent chromium {}}}}}}}} Kuv cov txheej txheem kev kho mob sib txawv. Los ntawm kev sim tshawb fawb thiab kev tshawb nrhiav ntawm lub tsev kawm ntawm cov tshuab hluav taws xob tau ua haujlwm ntawm kev siv hluav taws xob tuaj yeem ua rau cov khoom siv hluav taws xob hauv tsev kawm ntawv.

Ob leeg ferrous sulfate thiab sodium bisulfite tuaj yeem zoo kho cov roj av, tab sis ferrous sulfate kev kho mob yog ntau dua, tab sis nws tsim tawm ntau sludge. Sodium Bisulfite kev kho mob muaj qhov sib txawv ntawm kev tsim kom muaj tsawg dua sludge, tab sis yog me ntsis kim dua ferrous sulfate kev kho mob.

Vim tias cov txheej txheem Sulfate tsis tas yuav tsum muaj kev kho rau PHOO thiab yog qhov tsim nyog dua, nws yog qhov tsim nyog rau kev kho kom ntev ntawm cov khoom loj ntawm cov dej khib nyiab. Cov Sodium Bisulfite txoj kev, thaum siv sijhawm ntev dua thiab tsim nyog dua rau cov nroj tsuag electroplating me me uas yuav tsum tau kho kom zoo.
