在工业废水处理中,作为预处理单元的水解（酸化）反应器,不但降低了废水的COD_Cr,而且提高了废水的可生化性。作者论述了水解（酸化）反应器的特点及原理;介绍了水解（酸化）反应器的类型及其在工程应用中的效果;讨论了影响水解（酸化）反应器运行的主要因素及其设计要点;展望了水解（酸化）反应器的应用前景及研究领域。

The hydrolysis (acidification ) reactor as a pretreatment cell in the actual industrial wastewater treatment can reduce the COD_Cr,and also raise the wastewater biodegradability.This paper dissertates the characteristics and principle of hydrolytic(acidification)reaction,and introduces the type of hydrolysis (acidification )reactor and the dfficiency in engineering application.It alse discusses the main factor influenciong on the operation of hydrolusis (acidification )reactor.At the end,this paper prospects the applied foreground and research field
