| Abstract: | In Chongfu Tannery Wastewater Treatment Plant,the base dosing pretreatment,cation PAM flocculation settling,and activated sludge process were used to treat wastewater before tanning,and good results were obtained. The removal rate of COD is 85% in the biological stage. A small amount of powdered activated carbon is subsequently added to further strengthen treatment,and the effluent COD is less than 85 mg/L. |
