沉浸式膜生物反应器的技术开发与应用

STUDY ON THE TECHNOLOGY DEVELOPMENT AND APPLICATION OF IMMERSED MEMBRANE BIOREACTOR

MBR(膜生物反应器)是近来发展较迅速的一种新型的污水处理工艺,具有占地少、能耗低等优点,成为水处理行业中开发的热点。阐述膜生物反应器(MBR)的发展背景及研究进展,介绍其特点、处理机理。对膜片的性能以及MBR的运行进行系列分析及开发研究,针对膜污染的控制与清洗提出工程应用中的解决方法,开发一种改性有机平板膜组成的动态膜生物反应器,改善了膜运行过程的膜污染问题。分析MBR膜的开发方向及应用前景。

MBR ( membrane bioreactor) , as a new type of waste - water teareating methods, develops very fast in recent years, which has the advantage of low energey cost and fewer land taking. In this paper, we introduce the development background and re-search progress of MBR, its characteristics and trea-ting theroy of waste - water, analyzing its developing trend and application future. We study the perform-ance of MBR, analyzing the operating process, puting forward membrane pollution controll methods in pro-ject application, exploiting a new kind of dynamic flat membrane which may improve membrane pollution.
