摘要
研究了不同条件下混凝强化预处理生活污水的去除效果。试验表明:复配聚丙烯酰胺(PAM)后,聚合氯化铝(PAC)、聚合氯化铝铁(PAFC)投加量大于40 mg/L,出水COD、SS、TP分别在80 mg/L、50 mg/L、0.5 mg/L以下,前者沉降性能明显,且二者对磷的去除与PAM的投加量没有显著关系。
Domestic sewage by coagulation enhanced under different conditions were investigated.The results are as follows: the COD,SS and TP of water outlet is respectively within the water 80 mg/L,50 mg/L and 0.5 mg/L when the dosage of PAC or PAFC is greater than 40 mg/L and combination with polyacrylamide(PAM).The sedimentation performance of the former is More visible and the removal of TP is notable relationship with PAM of the dosage of PAC or PAFC.
