以浸没式超滤膜为核心的短流程净水工艺的应用与思考

Application and reflection on the submerged-ultrafiltration-membrane centric shortened water treatment process

以浸没式超滤膜为核心的短流程净水工艺自问世以来受到业界的广泛关注。该工艺为净水厂建设和改造提出了一条将预处理、超滤、浓水回收、污泥浓缩、排泥等工序集合在一个构筑物中运行的全新技术路线,有着广阔的应用前景。从该工艺各个环节的特点出发,进行从设计到运行的多角度思考,提出了一些自己的理解,抛砖引玉与大家共同探讨。

The subermerged-ultrafiltration-membrane centric shortened water treatment process has been a hot topic in water industry ever since its creation.This process offers a new technical route to combine the pre-treatment,ultrafiltration,concentrated water reusing,sludge thickening,and sludge drainage into a structure,which has a broad application potential.According to the characteristics of every step in this process,this paper brought forward some understandings from the multiple angles of design and operation,in the hope of touching off a discussion and throwing a minnow to catch a whale.
