城市污水污泥现状及未来的发展

Present Situation and Future Development of Sludge Treatment in Municipal Sewage Sludge

大量剩余污泥已经成为了水处理发展的难题。我国污泥产量呈现着逐年递升的趋势,但是对于污泥处理与处置并没有与之协调发展。虽然一些污泥的处理处置方案已经在我国得以应用。但是这些工艺均是借鉴国外经验。由于我国污泥的性质和对于污泥的要求与国外存在差异,这就需要我们发展符合我国国情的污泥处理处置方案来解决污泥问题。本文综述了生活污水污泥处理处置的现状及对于我国污泥未来发展的思考,为污泥的处理处置的进一步发展提供基础。

Large amount of excess sludge has become a problem in the development of water treatment.China's sludge production shows a trend of increasing year by year,but it is not matched with sludge treatment and disposal.Although some sludge treatment and disposal programs have been applied in China.But these processes are basically used for reference from foreign experience.Due to the differences in the properties and requirements of sludge between China and foreign countries.This requires China to develop a sludge treatment and disposal scheme in line with the national conditions of our country to solve the sludge problem.This article review the current status of domestic sewage sludge treatment and its considerations for the future development of sludge in China,providing a basis for sludge treatment.
