| 摘 要： | 运用磁种混凝技术处理校园生活污水,通过分析原水水质,磁种（Fe3O4）、混凝剂PAC（聚合氯化铝）或PAS（聚合硫酸铝）、助凝剂PAM（聚丙烯酰胺）投加方式及投加量考察对COD去除效果的影响。实验表明：磁种的添加量和添加方式对水处理起到关键性作用。先添加磁粉0.3g/L,再添加PAC 0.3g/L,PAM 0.002g/L混合搅拌出水COD去除率为78.90%,处理后COD含量43.60mg/L,达到排放标准。

| Abstract: | Base on analysis the schoolyard wastewater quality,experiments study on the adding order and dosage of magnetic seed（Fe3O4）、coagulants（PAC、PAM）and coagulant aid（PAM） to remove COD.The result by orthogonal test shows that： when the pH of water sample was 6.5,added magnetic seed 0.3g/L firstly,then PAC dosage was 0.3g/L and PAM 0.002g/L,the removal of COD reached 78.90% and the outlet water quality is better than standard A of the first class in Discharge standard of pollutants for municipal wastewater treatment plant（GB 18918-2002）. |
