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），BOD5/COD，variation of organic matters，enzyme activity and changes of microbial population. Currently，although hydrolytic acidification process is widely 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.
