摘要
以生活污水为研究对象,分别对PAC、聚硅酸铝铁、氯化铁、PAM等4种混凝剂的除磷效果进行了实验分析,同时考察了4种混凝剂对氨氮、COD的去除效果。实验表明:当氯化铁投加量为150 mg/L时,对总磷、COD去除效果最佳,4种混凝剂对氨氮去除效果都很差。
With domestic sewage as the research object, experimental analyses on the phosphorus removal effect of PAC, poly aluminum ferric, ferric trichloride, PAM were carried out. Also removal effect of ammonia and COD were analyzed. Experimental results showed that： when the dosage of ferric trichloride was 150 mg/L, the total phosphorus and COD removal efficiency was highest. However, the efficiency of ammonia removal was low.
