摘　　要：有机物的厌氧生物处理一般经过三个阶段:水解阶段、产酸发酵阶段和产甲烷阶段;研究证明,产酸相不同发酵类型的形成对产甲烷相乃至整个工艺的稳定运行具有至关重要的作用,此外,污泥厌氧消化过程所产生的大量的挥发性脂肪酸(VFAs),如乙酸、丙酸、丁酸及戊酸等,还可作为化工原料用于发酵工业生产各种高附加值产品。近年来,产酸发酵受到越来越多的关注,该文主要对污泥产酸阶段的产酸发酵类型、产酸发酵细菌的生态学、产酸过程的影响因素和生态因子以及产酸发酵的液相末端产物VFAs的测定方法进行了论述。Anaerobic biological treatment of organic compounds generally went through three stages ： hydrolysis stage, acidogenic and methanogenic stages of fermentation stage;Studies had shown that different fermentation types of acid formation played an important role in the whole anaerobic process, in addition, a large number of volatile fatty acids （VFAs） were produced during the anaerobic digestion process, such as acetic acid, propionic acid, butyric acid, etc. , could be used as chemical raw material for fermentation production of high value - added industrial products, the activated sludge acid fermentation type, the ecology of the acid producing bacteria, the impact factors of acid production process and the determination＇ of VFAs were discussed in this article.
