摘　　要：主要考察了膜生物反应器和传统活性污泥工艺之间的差异,分别从污泥驯化、出水质量、生物相、混合液污泥的物理特性、反应器内微生物累积情况几方面分析它们的不同之处。总的来说,膜生物反应器结合生物化学降解作用和膜分离的特点,与传统活性污泥工艺相比有许多优势,在废水处理工程中更有应用前景。The differences between membrane bioreactor and conventional activated sludge process were investigated and analyzed from the aspects of sludge domestication, effluent quality, microbial community, physical characteristics of the mixed sludge, accumulation of microoganisms in reactor. Generally speaking, membrane bioreactor has more advantages than conventional activated sludge for it combines effects of biochemical degradation and characteristics of membrane separation simultaneously, and will has brighter application foreground in waste- water treatment engineering.
