摘　　要：我国剩余污泥量非常大,有效利用存在诸多难题,挥发性脂肪酸(VFA)是剩余污泥厌氧发酵的重要产物,也是一种有极高利用价值的有机碳源。本文主要阐述了剩余污泥中微生物厌氧消化的过程及产物和参与厌氧消化反应的微生物情况,总结了处理剩余污泥的方法,指出资源化处理剩余污泥的重要性,并对污泥高温条件下产生的VFA浓度数据进行了分析,最后对城市的剩余污泥处理方式进行探讨和展望。There is a large quantity of excess sludge in China and it is very difficult to be effectively utilized.Volatile fatty acid(VFA)is an important product of anaerobic digestion of excess sludge.Also it is a source of organic carbon with high utilization value.This thesis mainly expounds the process and product of microbial anaerobic digestion in excess sludge,the species of microbial which participate in anaerobic digestion reaction process.Summarizes the treatment methods of excess sludge,the importance of resource treatment of excess sludge,analyzing the concentra⁃tion data of VFA produced by the excess sludge under high temperature conditions.Take the prospect of the treat⁃ment methods of excess sludge.
