The efficiencies of coagulation treatment of pulping and papermaking effluent by using PAC and PFC were compared. Influence of the factors such as the amount of coagulants and pH value on the flocculation effect was discussed. The optimum process conditions were obtained by analyzing the results of different coagulation in terms of the decoloration rate and the removal rate of CODCr, The experimental results showed that: When pH value is 8 and dosage of the coagulant is 30 mg/L pulping and papermaking effluent treatment using PFC coagulant is more effective and less expensive than PAC, the resulting 90% decoloration rate and 43% removal rate of CODCr.
