摘要
选择聚合氯化铝(PAC)和聚合硫酸铁(PFS)作为混凝剂,聚丙烯酰胺(PAM)作为助凝剂,对海河水在低温条件下的浊度去除及CODMn去除进行研究.结果表明,PFS对于海河水浊度和CODMn去除性能较好,其最佳投加量为20mg/L;添加助凝剂PAM可以改善絮凝体的沉降性能,但不能提高混凝沉淀过程对水体浊度和CODMn的去除性能.
The removal effects of turbidity and COD from raw water of the Haihe River in low temperature by using polyaluminum chloride (PAC), poly-ferric sulfate (PFS)and cationic poly-acrylamide (PAM) are studied . The results indicate that PFS can efficiently remove turbidity and COD from raw water and the best PFS dosage is 20 mg/L; when coagulant aid PAM is used, the sedimentation performance of floel is improved, but there is no obvious improvement for removal of turbidity and COD.
