城市污泥厌氧消化产沼气资源化研究

Resource Reuse Research on Methane Produced from the Anaerobic Digestion of Municipal Sludge

系统地综述了我国城市污泥处置与利用的现状和趋势,并重点讨论了污泥厌氧消化产沼气的可行性,介绍了提高消化速度的先进技术以及生物法沼气脱硫技术。认为污泥厌氧消化产沼气的资源化利用是符合我国国情的,并将成为我国污泥处置与利用的一种有效途径。

Municipal sludge is not only one kind of pollutants and but a kind of resources, and more and more attention should he paid on how to reasonably use it. In this paper the status and trend of the disposal and use for the municipal sludge in our country is systematically summarized, especially the feasibility of methane produced from the anaerobic digestion of the sludge is discussed and the advanced technology on the improvement of digestion speed is also introduced, as well as the methane desnlphurization technology by hioteehnology. The resource reuse research on the methane produced from the anaerobic digestion of the sludge conforms to the situation of China and it will he an effective method in the disposal and use of sludge in our country.
