市政污水厂污泥处置技术探讨

Discussion on Municipal Sewage Plant Sludge Disposal Technology

我国市政污水处理厂污泥处置能力不足,大量污泥没有得到规范化的处置,直接给水体、土壤和大气带来"二次污染",不仅降低了污水处理设施的有效处理能力,而且对生态环境构成严重威胁,同时也造成资源的极大浪费。针对上述问题,对市政污泥处置的几种常规处置技术进行了分析探讨,提出了污泥处置的发展方向。

China＇s municipal sewage treatment plant sludge disposal ability is insufficient, a large quantity of sludge has not been standardized disposal, directly to water, soil and air ＂secondary pollution＂, not only reduces the effective processing capacity of sewage treatment facilities, but also pose a serious threat to the ecological environment, but also caused a tremendous waste of resources. In view of the above problems, several conventional disposal technologies of municipal sludge disposal were analyzed and discussed, and the development direction of sludge disposal was put forward.
