摘　　要：在实验室运用二次通用旋转组合设计研究苏州河道水处理工艺,系统分析了磁絮凝工艺处理苏州河道水的四个影响因素(PAC投加量、PAM投加量、磁粉投加量、沉淀时间)对磁絮凝效果的影响效应。并运用方差分析、回归模型方程分析、单因子效应分析以及双因素交互效应分析,得出最佳工况为PAC投加量15 mg/L、PAM投加量0.58 mg/L、磁粉投加量2.7 mg/L、沉淀时间2.1 min,此时理论上浊度可达到0.73 NTU,浊度去除率为97.2%,用此参数进行试验,得到实际浊度为0.82 NTU,实际浊度去除率可达96.9%。River water in Suzhou was treated by magnetic flocculation with quadratic general rotary combination design,and effects of four factors(PAC dosage,PAM dosage,magnetic powder dosage and settling time)on magnetic flocculation performance were analyzed systematically.By using variance analysis,regression model equation analysis,single factor effect analysis and two factor interaction effect analysis,the optimal operating parameters were obtained:PAC dosage of 15 mg/L,PAM dosage of 0.58 mg/L,magnetic powder dosage of 2.7 mg/L and settling time of 2.1 min,and the expected effluent turbidity was 0.73 NTU with the removal efficiency of 97.2%.When these parameters were adopted in the experiment,the actual effluent turbidity was 0.82 NTU with removal efficiency of 96.9%.
