摘要:
］通过烧杯实验，考察了聚合氯化铝(PAC)、氯化铁(FeCl3)及聚合硫酸铁(PFS)对二级出水中磷的去除效果及其影响因素，并对混凝剂的经济性及选用标准进行了讨论.结果表明，PAC、FeCl3及PFS除磷最佳pH值范围分别为6~9、7~9和7~9.对于较低浓度含磷的二级出水，宜采用PFS除磷，可以在混凝剂投加量较低的条件下，获得较高的除磷率.欲使初始总磷质量浓度为1.735 mg/L的二级出水经混凝处理后，其出水总磷浓度达到《地表水环境质量标准》(GB 3838—2002)中Ⅲ类水体的水质标准，PAC、FeCl3、PFS的最佳投药量分别为40、20、25 mg/L
Abstract:
Three various coagulants，poly-aluminum chloride (PAC)，ferric chloride(FC) and poly-ferric sulfate (PFS)，were applied respectively to remove phosphorus in wastewater by jar tests.The influence of coagulant dosage and other effective factors were discussed.Meanwhile，technical economy analysis and choice of the three coagulants were discussed.The results showed that the optimum pH of P removal by PAC，FC and PFS were 6~9，7~9 and 7~9 respectively for the removal of phosphate，and PFS should be chosen when the original P concentration was lower.In order to find the optimum coagulant dosage to make the treated secondary effluent with TP of 1.735 mg/L in accordance with the quality of Ⅲ category surface water of the standard GB 3838—2002，the dosage was 40 mg/L with PAC as coagulant，20 mg/L with FeCl3，and 25 mg/L with PFS
