课题探讨电化学与有机膜耦合处理含重金属的有机废水，主要应用电场对废水中粒子的电泳迁移、电凝聚和电化学氧化作用来缓解膜污染。通过探讨电场对有机微滤膜过滤含重金属有机废水的影响，评价不同电场与水力条件下的过滤性能。实验研究了不同电压、跨膜压差（TMP）和错流流速条件下HS及Cu离子通量和截留率的衰减情况，根据截留率和通量的大小确定电有机膜耦合的最佳电压、TMP和错流流速，并观察过滤后膜受污染的情况。实验结果表明，电场作用能够降低膜污染程度。高电场、TMP和错流流速有利于HS的迁移和凝聚以及Cu2+的迁移。在电压为100V，TMP为300rpm，错流流速为0.1m/s时，膜过滤HS和Cu离子混合溶液的效果最好，HS的截留率达到91.53%，Cu2+的去除率达到89.85%。21106

Title Organic membranes coupled with electrochemical study on treatment of organic wastewater containing heavy metal
Abstract
The topic discusses with the coupling of organic membrane and electrochemical to deal with organic wastewater containing heavy metals. Mainly research is on the application of electric field on the electrophoretic migration, electro-coagulation of particles electrochemical oxidation in wastewater to mitigate membrane fouling. By exploring the effect of the electric field filter organic wastewater containing heavy metals through the organic microfiltration membrane, evaluate the filtration performance under different conditions of electric and hydraulic parameters. Experimental study the attenuation of the flux and retention rate of HS and Cu2+ on different voltages, TMPs, and the cross-flow velocities, depending on the size of the retention rate and flux to determine the optimum voltage, TMP, and cross-flow velocity. And observe the morphology of contaminated filtration membrane. Experimental results show that the electric field can reduce the level of membrane fouling. High electric field, TMP and cross-flow velocity of flow in favor of HS migration and cohesion as well as the migration of Cu2+. When voltage of 100V, TMP of 300rpm and the cross-flow velocity of 0.1m/s were applied, the mixture of HS and Cu2+ revealed the best filtering effect. The final interception rate of HS is 91.53%, the removal rate of Cu2+ is 89.85%.
