微污染原水生物膜法预处理技术概述

The Conspectus of Pretreatment Technology of Micro- polluted Water Resource through Biofilm Reactor

饮用水源的污染对人类的健康和传统的净水工艺构成了威胁,生物预处理技术能较好地解决这一问题。本文对目前生物膜法预处理微污染原水的几种工艺如生物滤池、生物转盘、生物接触氧化、生物流化床等进行了介绍,指出了其优点及存在的缺陷。

The pollution of drinking water resource poses a great threat to the health of people and incapacitates the traditional water treatment process. Biological pretreatment is a way out to the situation. The paper discussed the current pretreatment technology through biofilm methods: biofilter, rotating biological cantactor, biological contact oxidation reactor, biofluidized bed reactor and Land - sand processing system, at the same time their merits and shortcomings are also dis- cussed.
