以重庆大渡口污水处理厂的二级出水为考察对象，研究了自制聚合硫酸铝铁（PAFS）投加量、水体初始pH对污水处理厂二级出水的TP、NH3-N去除效果的影响。研究表明：当PAFS投加质量浓度为13 mg/L时，剩余TP质量浓度为0.094 mg/L，达到污水排放一级A标准，同时NH3-N去除率为24.8%。与市售混凝剂PAFC、PAC、PFS相比，PAFS具有较好的混凝效果和较低的投加量，同时PAFS还具有更强的电荷中和和吸附架桥能力。
以重慶大渡口汙水處理廠的二級齣水為攷察對象，研究瞭自製聚閤硫痠鋁鐵（PAFS）投加量、水體初始pH對汙水處理廠二級齣水的TP、NH3-N去除效果的影響。研究錶明：噹PAFS投加質量濃度為13 mg/L時，剩餘TP質量濃度為0.094 mg/L，達到汙水排放一級A標準，同時NH3-N去除率為24.8%。與市售混凝劑PAFC、PAC、PFS相比，PAFS具有較好的混凝效果和較低的投加量，同時PAFS還具有更彊的電荷中和和吸附架橋能力。

The secondary effluent of Dadukou Wastewater Treatment Plant in Chongqing has been investigated. The effects of the dosage of self-made polymeric aluminum ferric sulfate (PAFS),and initial pH of water body on the re-moving effectiveness of total phosphorus (TP) and ammonia nitrogen (NH3-N) from the secondary effluent in the wastewater treatment plant are studied. The research results show that when the mass concentration of PAFS is 13 mg/L,the residual TP mass concentration is 0.094 mg/L,the first class A wastewater discharge standard can be reached. Meanwhile NH3-N removing rate reaches 24.8%. Compared with PAFC ,PAC and PFS which are sold in markets,PAFC has higher coagulation effectiveness,and lower dosages. Furthermore,PAFC has stronger charge neutralization and adsorption bridging capacities.
