| 摘 要： | 采用聚丙烯酰胺（PAM）、聚合氯化铝（PAC）、硫酸铝（AS）,通过混凝沉淀处理钨矿废水。对实验数据进行层次分析法分析,确定0.5%硫酸铝为最佳混凝剂,进一步实验结果表明：0.5%硫酸铝在pH=9,投加量为10~12.5 mg/L时,处理后废水可达到广东省水污染物排放限值标准（DB4426—2001）一级标准。

| Abstract: | The experiment of the wolfram-wastewater treatment by coagulant sedimentation with PAM and PAC and AS shows that 0.5% AS is the best coagulant through the Analytic Hierarchy Process,and when pH=9 and dosage is within 10～12.5 mg/L,the treated wastewater can attain to the A standard of "discharge limits of water pollutants" in Guandong Province(DB4426—2001). |
