摘　　要：污泥厌氧发酵是污水处理厂对污泥实现部分稳定化、减量化和资源化的常用策略。污泥厌氧发酵会产生短链脂肪酸(VFA),且由于发酵时间短、经济价值高、应用范围广而广受关注。综述污泥厌氧发酵产酸的研究进展,有助于污泥的资源化回收。本文讨论了C/N值、pH、温度,以及污泥停留时间等工艺参数对污泥厌氧发酵产酸的影响,并总结了4种预处理方式(物理预处理、化学预处理、生物预处理、联合预处理)对污泥厌氧发酵的影响,以期为提高污泥厌氧发酵产酸效率提供参考。Anaerobic fermentation of sludge is a common strategy to achieve partial stabilization,reduction and recycling of sludge in sewage treatment plants.Anaerobic fermentation of sludge can produce short-chain fatty acids(VFA),and attract wide attention due to its short fermentation time,high economic value and wide applications.This paper reviews the research progress of VFA production by anaerobic fermentation of sludge,and contributes to the recovery of sludge resources.The effects of process parameters such as C/N value,pH value,temperature and sludge residence time on the production of VFA in sludge anaerobic fermentation are discussed,and the effects of four kinds of pretreatment(physical pretreatment,chemical pretreatment,biological pretreatment and combined pretreatment)on anaerobic fermentation of sludge are discussed,in order to provide suggestions for improving the production of VFA by anaerobic fermentation of sludge.
