摘要:阐述了水解酸化工艺的机理,介绍了其以独立的エ艺或与其他エ艺相结合在印染废水处理中的应用,并
分析了水解酸化过程中徽生物及其产生的胞外酶的作用。另外,本文还总结了水解酸化阶段的优化调控方法
包括直接投加菡剂或共代谢基质类物质和授加激活剂,并概括了水解酸化调控效果的评价指标,包括pH值、色
度、挥发性脂肪酸VFA、BOD/COD、有机物组成的变化、酶活、微生物种群结构变化。目前,虽然水解酸化
エ艺在印染废水处理中应用广泛且有所成效,但是对其中微生物的作用机制尚不十分了解,无法有针对性地对
功能菌群进行优化调控。本文提出在深入探讨徽生物作用机理的基础上,针对功能菌群进行优化调控,是提高
水解酸化速率的一个有效途径,从而最大限度地发挥水解酸化工艺在印染废水处理中的作用

Abstract: The paper sketched the mechanisms of hydrolytic acidification process, introduced the
applications of the independent process or combined with other technologies in dyeing wastewater
treatment, and analyzed the roles of microbes and extracellular enzymes in hydrolytic acidification
process. This paper also summarized the optimization regulation methods of hydrolytic acidification
stages, including adding microbial agents or co-metabolism matrixes and activators. The evaluation
indexes of hydrolytic acidification regulation effect were generalized, including PH value
chromaticity, volatile fatty acids(VFA), BOD/COD, variation of organic matters, enzyme activit
and changes of microbial population. Currently, although hydrolytic acidification process is widel
used and made some achievements in dyeing wastewater treatment, the mechanisms of microbes in it
are still not clear making the specifically regulations of functional microbes difficult. This paper
proposed an effective way to improve the rate of hydrolytic acidification by regulating the functional
microbes based on studying microbial mechanism. The effects of hydrolytic acidification process in
dyeing wastewater treatment may be maximized
