摘　　要：膜芬顿是通过将传统芬顿加以改进,与超滤膜过滤有机结合而产生的一种新型污水处理技术,已证明能有效去除污水中的COD、悬浮物、总磷、氟化物等污染物组分。通过一系列实验室研究、中试和商业规模示范工程的运行,初步证实了膜芬顿技术的适用性和高效率,表明它集成了高级氧化、混凝、化学沉淀、吸附、膜过滤等多种水处理机理。生产性示范工程长期运行结果表明,该工艺用于处理精细化工废水时,膜芬顿出水平均COD、总磷可达到《地表水环境质量标准》(GB 3838—2002)的Ⅲ类水标准,运营成本约为1.89元/m^3。针对印染行业因水回用而产生的RO浓水的中试结果显示,膜芬顿出水COD、悬浮物可达到《城镇污水处理厂污染物排放标准》(GB18918—2002)一级A标准,总磷可达到地表水环境Ⅲ类水标准。The membrane Fenton technology is newly invented by coupling modified Fenton process with ultrafiltration.It has shown effective removal of COD,total suspended solids(TSS),total phosphorus(TP),fluoride and other contaminants in wastewater.Through a series of laboratory research,pilot and commercial scale demonstration projects,the applicability and high efficiency of membrane Fenton technology have been preliminarily verified,indicating that it integrates various mechanisms such as advanced oxidation process(AOP),coagulation,chemical precipitation,adsorption and membrane separation.The long operation of a commercial scale demonstrative project showed that the average effluent COD,TP could consistently meet levelⅢcriteria in the Environmental Quality Standards for Surface Water(GB 3838-2002).The operating cost was about 1.89 yuan/m^3.The pilot research on treatment of concentrated RO reject water from dyeing and printing industry showed that the effluent COD and TSS could meet the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002),while TP could meet levelⅢcriteria in Environmental Quality Standards for Surface Water(GB 3838-2002).
