Use it as coagulant and take some biodegraded coking effluent to carry on the coagulation experiment. The optimum dosage is 3.0 mL/L and the optimum pH range is 6.5 -7.5. Under the optimum conditions,the removal rates of CODCr,phenol,T -CN,turbidity and chroma are 55.5%,61.3%,83.7%,90.2% and 97% respectively. 查看更多0个回答 . 2人已关注
