摘　　要：市政污泥厌氧发酵产挥发性脂肪酸(VFAs)强化城市污水脱氮除磷是污泥处理、处置的有效方式之一,实现了污水处理行业“以废治废”的目的。水解环节是污泥发酵产酸的限制性步骤,对污泥进行预处理提高污泥水解效率是解决污泥发酵产酸产率和产量低的有效途径之一。目前报道的污泥预处理方法众多,改善发酵过程的机理和效果不尽相同。总结和对比分析了目前常见的促进污泥发酵产VFAs的预处理工艺,阐述了各预处理工艺的原理、特性和应用效果,对比分析了其经济成本,综合分析了当前存在的问题,并对未来发展方向进行了展望,以期为污泥发酵产酸工程方案设计和优选提供文献借鉴。Producing volatile fatty acids(VFAs)by anaerobic fermentation from municipal sludge to strengthen nitrogen and phosphorus removal of urban sewage,is one of the most effective sludge treatment and disposal methods to realize the purpose of treating waste with waste.However,hydrolysis is the limiting step of VFAs production from sludge.Improving sludge hydrolysis efficiency by pretreatment is an efficient way to increase VFAs yield significantly.Many pretreatment strategies have been reported,and the mechanism and impact of enhancing the VFAs production process are different.Therefore,this review summarized and compared the commonly used pre-treatment processes for promoting sludge fermentation to produce VFAs,elaborated on the principles,characteristics,and application effect of each pre-treatment process,compared and analyzed their economic costs,comprehensively analyzed their existing problems,and looked forward to future development directions,in order to provide literature reference for the design and optimization of sludge fermentation acid production engineering schemes.
