摘　　要：应用响应面法分析磁絮凝减缓膜污染的影响因素和工艺效果。运用Design Expert软件,以聚合氯化铝(PAC)投加量、磁粉投加量和磁化时间为因素,利用中心组合设计分析了3个因素对膜污染速率的影响。试验结果表明,PAC投加量和磁粉投加量以及磁粉投加量和磁化时间之间对延缓膜污染的协同交互作用显著。响应面法建立的模型拟合程度较高、误差小,可用于磁絮凝-膜过滤工艺条件的预测和优化。Response surface method was applied to analyze the influencing factors and efficiency for magnetic flocculationmitigating membrane fouling. The experiments were designed by using the Design-Expert software in the aspect of poly aluminumchloride(PAC) dosage, magnetic particles dosage and magnetization time. Box-Behnken design was applied to analyze the effect ofinfluencing factors on membrane fouling rate. The results show that the synergistic effects of PAC dosage and magnetic particles dos-age, magnetic particles dosage and magnetization time are significant. Response surface method can be used to predict and optimizethe process of magnetic flocculation and membrane filtration, which is of relatively high fitting degree and the error is small.
