摘　　要：复合除磷剂包含聚合硫酸铁、硫酸亚铁、硫酸铝以及硫酸铜等有效成分,将复合除磷剂溶解后加入到生物曝气池出水中,经水力搅拌后进入二次沉淀池沉淀,总磷降至0.3 mg/L以下,出水优于《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准排放。A complex phosphorus removal agent contains active ingredients such as polymeric ferric sulfate, ferrous sulfate, aluminium sulfate and copper sulfate. Dissolve the compound phosphorus remover and add it to the biological aeration tank outlet water and settled in secondary sedimentation tanks with hydraulic agitating. Total phosphorus dropped below 0.3 mg/L.The effluent is better than the first A standard of "Discharge standard of pollutants for municipal wastewater treatment plant"(GB18918-2002).
