摘　　要：对混凝-磁分离法处理洗车废水进行了试验研究。将普通混凝和混凝-磁分离处理洗车废水的效果对比试验,并研究了适宜的磁粉与混凝剂的搭配组合和最佳投加量。试验结果表明纯铁粉与PAC+PAM为最佳组合,最佳投加量为铁粉250 mg/L、PAC、PAM投加量分别为100 mg/L、6 mg/L,处理出水的COD为46.05 mg/L,浊度为4.13 NTU。The treatment of car washing wastewater by coagulation and magnetic separation was conducted. The comparison between coagulation-magnetic separation and conventional coagulation was carried out. The optimal coagulant-magnetic powder and dosage was selected and determined through comparisons among the wastewater treatment effects of the 3 kinds of selected magnetic-powders and 4 kinds of selected coagulants. The results showed that the optimal dosage of pure iron-powders,PAC and PAM were 250 mg / L,100 mg / L,6 mg / L,respectively. The concentration of COD and turbidity was 46 mg / L,4. 13 NTU after treatment.
