摘　　要：为提高电絮凝—陶瓷微滤膜(EC/CMF)工艺在净化微污染水源水时的产水量(以水量综合指标表征),在前期单因素试验的基础上,采用响应曲面法优化工艺条件,考察电流密度、进水流量、跨膜压差及各因素间的交互作用对EC/CMF工艺水量综合指标的影响,得到多元二次回归模型。经响应曲面法分析,EC/CMF工艺的最佳运行条件为电流密度1.63 mA/cm2、进水流量2.94L/min、跨膜压差0.15MPa,在此条件下,水量综合指标的计算值最大,为44.5%。方差分析结果显示,构建的回归模型可靠度、精确度高,电流密度和进水流量间的交互作用对水量综合指标影响显著。In this paper,the response surface method was used to optimize the electrocoagulation-ceramic micro- filtration membrane （EC/CMF） process for purification of micro-polluted surface water so as to increase the water yield （represented by comprehensive water yield index）. The follow-up tests was designed on the basis of previous single-factor experiments,and the current density, feed flow, transmembrane pressure as well as their interactive effect on the comprehensive water yield index were investigated. The best EC/CMF operating conditions were current densi- ty of 1.63 mA/cm2 , feed flow of 2.94 L/min and transmembrane pressure of 0.15 MPa. Under these optimal condi- tions,the comprehensive water yield index achieved the highest calculated value of 44.5 %. The variance assessment showed that the regression model was reliable with high accuracy and the interaction among current density and feed flow were statistically significant to comprehensive water yield index.
