摘要
采用SBR—化学混凝处理城镇生活污水,结果表明:经SBR处理后,废水中的COD、氮、磷得到很好的去除,最佳的混凝工艺条件为:废水pH7.30左右,聚合氯化铝钙用量20mg/L废水,搅拌强度120r/min,搅拌时间15min,加入PAM用量0.15mg/L废水。
Using SBR--coagulation process to treat municipal sewage, the results show that the content of COD,nitrogen and phosphorus in the sewage can get a good remove after treated by SBR. The optimal condition of coagulation is as follow： the pH value of sewage is 7.30, the dosage of polyaluminiumcaleium is 20mg/L;agitating intensity is 120r/min, agitating time is 15min,dosage of PAM is 0. 15mg/L.
