| 摘 要： | 以位于太湖流域的某城市污水处理厂A/O处理工艺的尾水为对象,进行了化学混凝除磷试验.结果表明,无机高分子混凝剂PFS和PAC较其他无机低分子混凝剂具有更好的除磷效果,且铁系混凝剂比铝系混凝剂除磷效果要好,PFS的除磷效果最好,PAC次之;混凝剂投加量为15 mg·L-1时,可使处理后出水TP的质量浓度＜0.5 mg·L-1,混凝剂PFS当n(Fe3+)/n(P)为1.25时除磷效果最好,是一种高效的混凝剂,投加量少、成本低;混凝剂和助凝剂联用时,非离子型PAM对PAC和三氯化铁的助凝效果较明显.降低城镇污水处理厂尾水中磷含量,化学除磷方法是一种有效、可行的选择.

| Abstract: | The removal of Phosphorus by chemical coagulation was carried out for the A/O treatment water in a municipal sewage treatment plant situated in the Taihu Lake Basin.The results showed that inorganic macromolecules coagulant PFS and PAC had a better effect on phosphorus removal compared with other inorganic molecules coagulants.And phosphorus removal effect of iron-based coagulants was better than aluminum-salt coagulants.Among the coagulants,phosphorus removal efficiency of PFS was best,PAC took the second ... |
