摘　　要：采用膜生物反应器-反渗透（MBR-RO）组合工艺处理生活污水的过程中,MBR出水污染指数（SDI）在2.5^3.5之间,符合RO膜元件进水要求,且添加10mg/L阻垢剂后能有效控制RO膜的结垢问题。MBR-RO组合工艺的产水水质良好,其中常规水质指标COD（Mn）浓度〈0.05mg/L、NH4^＋-N浓度0.15mg/L、NO3^--N浓度2.82mg/L、NO2^--N浓度〈0.7mg/L、TP浓度0.12mg/L,TOC浓度0.51mg/L,参照国家《生活饮用水卫生标准》中主要的73项指标分析,产水达到饮用水水质标准。本研究结果表明,采用MBR-RO组合工艺生产直接饮用再生水是可行的。The municipal domestic sewage was treated by a membrane bioreactor-reverse osmosis（MBR-RO）combined process.The SDI of MBR effluent was between 2.5and 3.5,which met the demand of RO influent,and the fouling of RO membrane could be controlled after adding 10 mg/L of the antisludging agent.The product water quality of MBR-RO was good,and NH4^＋-N,NO2^--N,TP and TOC concentrations of the effluent were respectively 0.15mg/L,2.82mg/L,0.12mg/L and 0.51mg/L,and the concentrations of COD（Mn） and NO2^--N were below 0.05mg/L and 0.7mg/L respectively in MBR-RO.According to the 73 major indexes in the national drinking water sanitary standard,the effluent could meet the drinking water quality.The result showed that MBR-RO combined process for direct potable reuse water production is feasible.
