This article compares the treatment effect of a series of coagulation tests,by changing the test conditions,and using a new type polymer coagulant,aluminum sulfate and PAC on wood-based pulp and paper mills integrated wastewater treatment. The experimental results show that at the best pH value and dosage conditions new polymer coagulant integrated pulp and paper deals with the waste water relatively the best.When pH is 8.29 and dosage is 175 mg·L^-1,even if CPAM is not added,the removal rate of COD,turbidity,chroma is 87.4%,96.4% and 89.5%.COD and chroma of the effluent are 90 mg·L^-1 and 32 times respectively,which can meet the first grade of secondary period of Local Standard Discharge Limits of Water Pollutants of Guangdong Province(DB 44/26-2001).
