摘　　要：采用FeSO_(4)作为絮凝剂,处理汽车制造厂涂装磷化废水。探究FeSO_(4)投加量、pH、搅拌时间、搅拌转速、沉降时间对总磷去除率的影响,在单因素实验的基础上选取部分因素进行响应面优化实验,实验结果表明:在FeSO_(4)投加量为310 mg/L、pH值为9、沉降时间30 min、搅拌时间15 min、搅拌转速200 r/min时测得总磷去除率最高,可达87.68%。FeSO_(4) was used as flocculant to treat phosphating wastewater from automobile factory.The TP removal rate was used as an evaluation index,and the effects of ferrous sulfate dosage,pH,stiring time,stirring speed and precipitation time were investigated.On the basis of single factor experiment,some factors were selected for response surface optimization.Optimal preparation process conditions are ferrous sulfate dosage 310 mg/L,pH 9,precipitation time 30 min,stiring time 15 min and stirring speed 200 r/min,at which the removal rate is 87.68%。
