摘　　要：实验以处理金属表面所产生的磷化废水为研究对象,系统地分析了在新型混凝剂的使用过程中,pH值、温度、石灰投入量、沉降时间、助剂A等因素对脱磷效果的影响。结果表明,含磷量为18mg/L、COD为300mg/L、SS为150mg/L、pH值为5.7～6.5的废水,石灰投入量为300mg/L、沉降时间为10min左右、温度为25℃、pH值调节至9.0、加入5mL助剂A处理后,废水中磷含量为0.25～0.35mg/L、COD为80mg/L、SS为60mg/L,满足《污水综合排放标准》(GB8978—1996)中的一级标准。A novel coagulant was used for phosphorous wastewater treatment. The dephosphorization effect of pH value, temperature, lime amount, subsidence time and additive A were analyzed. Wastewater was processed with phosphorus concentration18 mg/L, COD 300 mg/L,SS 150 mg/L, pH value 9.0～9.5,lime concentration 300 mg/L, subsidence time 10 min,temperature 25℃,additive 5 mL. The result showed that processed wastewater met Grade I of Integrated wastewater discharge standard (GB 8978-1996)with phosphorus concentration 0.25～0.35 mg/L, COD 80 mg/L and SS 60 mg/L.
