摘要：市政污水处理厂产生的污泥量大，其稳定性非常差，同时污泥具有一定的危害性，处置不当会产生二次污染。采用低温干化工艺处理市政污泥，其含水率可以降低到小于30%，处理后污泥运至发电厂进行掺烧。本文结合污水处理厂污泥低温干化实例，总结项目运行情况，提出工艺优化建议。

Abstract： The amount of sludge produced by municipal sewage treatment plants is large， and its stability is very poor， at the same time， sludge has a certain degree of harm， and improper disposal can cause secondary pollution. The low-temperature drying process is used to treat municipal sludge， which can reduce its moisture content to less than 30%， after treatment， the sludge is transported to the power plant for blending and burning. Based on the example of low-temperature sludge drying in a sewage treatment plant， this paper summarizes the project operation and proposes process optimization suggestions.
