摘　　要：相对于传统活性污泥法,膜生物反应器处理生活污水具有显著的优势。通过在自行设计、加工的浸没式中空纤维微滤膜生物反应器中试装置上连续处理两种生活污水,旨在研究中空纤维微滤膜组件的性能及其影响因素,膜水通量随膜组件内真空度的变化,膜水通量随运行时间的变化和膜污染产生的原因及防治措施。了解膜生物反应器对生活污水的净化效果,出水COD、NH3_N、表色色度和浊度随运行时间的变化,膜生物反应器内污泥浓度随运行时间的变化情况等。为下一步中空纤维微滤膜生物反应器商业化应用提供基础设计数据和运行参数。It is obviously advantageous for membrane biological reactor to treat municipal sewage over traditional active sludge process. Multispecies microbes in active sludge retained completely by submerged hollow fiber curtain-like micro-filtration membrane module with pore-size of 0.5 nun in an integrated pilot-scale membrane biological reactor self-designed. Meanwhile, the pilot plant comprised an auoxic zone to enable denitrification. In this experiment, two kinds of practical municipal sewage were continuously treated by using this membrane biological reactor in order to evaluate the properties of membrane module, such as the relationship between vacuum degree in membrane module and water flux of membrane, relationship between operational time and water flux of membrane and the way to prevent membrane pollution. Further, all sorts of water quality indexes for inlets and effluents, such as COD, turbidity, NH3-N and apparent colourity were measured in time. And the experimental results showed that there were so excelleut water qualities for outlet water as to meet the water-quality standards for urban miscellaneous consumption water. Moreover, the change of sludge conceuwations （MISS） was also monitored on every day. In conclusion, it is instructive for the designiug and operational data to commercial applications in the future, which are obtained from this pilot-scale membrane biological reactor.
