摘要
城市污水处理厂所产生的污泥,数量巨大,成分复杂。如何经济、有效地加以利用已成为目前环境工程中深为关注的课题之一。文章探讨了污泥资源化工作中厌氧消化工艺的温度、时间、污泥成分的最佳工艺条件和沼气产生量,以实现污泥工业化利用。
A large amount of sludge with complex components is produced in municipal sewage treatment plants. Recently how to make an economical, effective use of sludge has become one of the increasingly concerned issues in environmental science. And the optimal technological conditions such as temperature, time and components and methane volume in the anaerobic digestion process of sludge resource recovery are probed in this paper. The result is helpful for sludge industrialization.
