摘　　要：简略介绍了我国城市污水处理所面临的问题以及国内水解酸化工艺的研究现状,并进一步探讨了水解酸化池的工艺原理及其特点。结合实验,分别从废水中SS的去除、出水可生化降解性、对后续系统脱氮负荷的影响3个方面,对水解酸化池作为前置BAF组合工艺中的预处理单元的预处理效果进行了分析。结果表明,水解酸化池可有效降低SS浓度,平均浓度低于70 mg/L;可显著提高出水的可生化性,出水B/C的范围为0.43~0.55;TN平均去除率提高了30%以上,有效降低了后续处理单元的脱氮负荷。China’s existing problems in urban sewage treatment and current research status in hydrolysis acidification process are briefly introduced,and the process principle and characteristics of hydrolysis acidification pool are further discussed.Combined with experiments,the pretreatment effect by using a hydrolysis acidification pool as pretreatment unit for pre-denitrification biologically aerated filter is analyzed from three aspects,including SS removal from wastewater,biochemical degradability of effluent,and influences on denitrification load of subsequent system.The results show that hydrolysis acidification pool can effectively reduce the concentration of SS and make its average concentration drop to less than 70 mg·L^(-1).Hydrolysis acidification pool can also improve the biodegradability of effluent significantly,with an effluent B/C ratio in the range of 0.43-0.55.Average removal rate of TN is increased by more than30%,which reduces the denitrification load of subsequent system effectively.
