膜生物反应器（简称MBR）是将膜分离装置和二级生物反应器结合而成的一种新的处理系统，具有污染物去除效率高、出水水质好、生物反应器内的微生物浓度高的优点。

Membrane Bio-Reactor (MBR) is a kind of new process system combining membrane separation equipment and bio-reactor. MBR substitutes for secondary sedimentation tank of traditional biological process and has the following features including high removal efficiency of pollutants, good quality of produced water, high concentration of microorganism within bio-reactor.

u COD去除率：     >80%

u 悬浮物去除率：  >99%

u 出水浊度：      <5 NTU

u 出水SDI：       <3

u 回收率：         >90%

u Removal rate of COD:       >80%

u Removal rate of SS:          >99%
