| 摘 要： | 采用聚合硅酸铝和聚合硅酸铁两种混凝剂，比较了将混凝剂直接投加到反应器中和对生物反应器出水再进行混凝沉淀2种工艺的除磷效果，并对2种混凝剂的除磷效果进行了比较。结果表明：对于聚合硅酸铝，没有生物协同作用；对于聚合硅酸铁，投加量在40mg／L以下时具有生物协同作用，30mg／L时协同作用最明显；而且聚合硅酸铁的除磷效果好于聚合硅酸铝。

| Abstract: | Poly-aluminum silicate and poly-ferric silicate were used to compare the difference of phosphorus removal effect between feeding coagulant into biological reactor and coagulating, settling the bioreactor effluent. The phosphorus removal effects of two kinds of coagulants were also compared. Results indicated that for poly-aluminum silicate, there was no cooperative effect; for poly-ferric silicate, when dosage was less than 40 mg/L, there was cooperative effect and dosage of 30 mg/L was best. The phosphorus removal effect of poly-ferric silicate was better than that of poly-aluminum silicate. |

| Keywords: | bioreactor coagulant poly-aluminum silicate poly-ferrie silicate phosphorus removal co- operative effect |
