The application of JY 202 compound flocculant to the treatment of coking wastewater is introduced. Their mechanism of action has been discussed. The experiment shows that the efficiency of the flocculant is better in flocculation behavior when compared with the single inorganic high polymer flocculants. Through testing, the optimal technical condition are all be confirmed. The optimal pH value is 7.1, the amount of coagulant is 250 mg/L and the optimal temperature is 15 ~ 40 ℃. When time is 12 min, the removal rate of SS goes up to 92%. JY 202 compound flocculant is applied to industrial production, the removal rate of CODCr, SS and chroma reaches 51.2%, 92.7% and 85.7%. The indexes of the outgoing water come up to the Second Grade Discharge Standard.
