Abstract：This paper reviewed the technology to enhance anaerobic fermentation of waste activated sludge (WAS) in municipal wastewater treatment plants,especially focused on the volatile fatty acids (VFAs) produced in the process of WAS fermentation,which can be easily used as carbon sources for microorganisms,which on the other hand can improve biological nutrients (nitrogen and phosphorus) removal efficiency in wastewater treatment;thus,much attention has been attached to technology to obtain the fermentation liquid rich in VFAs.In this paper;factors affecting WAS fermentation and the mechanisms were presented;and various techniques to enhance were introduced,their advantages as well as limitations were emphasized on the basis of the cost-benefit analysis.
