| 摘 要： | 采用聚合硫酸铝铁(PFSA)对城市污水处理厂生化出水混凝除磷,考察PFSA投加量对磷和出水pH的影响,污水pH、沉淀时间对混凝除磷效果的影响.同时进行了聚合硫酸铁(PFS)、硫酸铝的混凝除磷比较实验.结果表明,聚合硫酸铁铝(PFSA)具有对出水pH的影响较小,对磷去除率高,pH值适用范围宽的优势.PFSA在投加量为6.0mL/L时,沉淀时间为40min时,出水磷0.24mg/L,磷去除率可以达到84%,出水满足辽宁省污水综合排放标准(DB2008).

| Abstract: | The paper studies on dephosphorization from urban waste water coagulation with polymeric ferroaluminium sulphate(PISA),.We examine the effect of additive PSIA to phosphorus and PH in water, and the effect of water PH and sediment time to dephosphorization efficiency.We also conduct the.contrasted study by using dephosphorization from coagulation with ferrous sulphate and aluminium sulphate.The results show that, PSIA has much advantages, such as high dephosphorized rate, low effect on water PH, and wide adaptable PH.The produced water is 0.24mg/L and dephosphorized rate reaches 84% when additive PSIA is 6.0mL/L and sediment time is 40 min.Produced water satisfy the Liaoning comprehensive water drain standard. |
