污水处理工艺介绍系列之MBR工艺

1、定义

膜生物反应器（简称MBR）是高效膜分离技术与活性污泥法相结合的污水处理技术。中空纤维膜的应用，取代生化工艺中的二沉池，进行固液分离。膜的高效截留作用，可以有效截留硝化菌，使硝化反应顺利进行，有效去除氨氮；同时可以截留难于降解的大分子有机物，延长其在反应器中的停留时间，使之得到最大限度的分解。

2、MBR膜工艺分类

分置式：膜组件和生物反应器分开设置。生物反应器中的混合液经循环泵增压后打至膜组件的过滤端，在压力作用下混合液中的液体透过膜，成为系统处理水。

一体式:膜组件置于生物反应器内部，进水进入膜-生物反应器，其中的大部分污染物被混合液中的活性污泥去除，再在负压作用下由膜过滤出水。

复合式：形式上也属于一体式膜-生物反应器，所不同的是在生物反应器内加装填料，从而形成复合式膜-生物反应器，改变了反应器的某些性状。
