Compared with the traditional two-phase anaerobic process, there are more microbe populations in the hydrolytic acidification reactors or anaerobic reactors than those in the single phase, the combined anaerobic reactors appeared more stable, and the bionomic condition would be easily realized.

与两相厌氧工艺相比，复合厌氧法中，水解酸化反应器和厌氧反应器中的菌群种类要比单一的产酸相或甲烷相中的多，所构成的微生态系统更为稳定，所需要的生态条件比较容易实现。

The metabolism and succession of microbial population took place ceaselessly during the fermentation and led to microbial polymorphism which mainly presented as anaerobe,methane bacteria,caproic acid bacteria,lactic acid bacteria,sulfate reducing bacteria,and nitrate reducing bacteria etc.

窖泥糟醅是发酵过程微生物栖息的生态环境，其中微生物种群随发酵过程的进行而不停地演替和代谢，具有明显的多态性。其微生物种群的多态性主要表现为厌氧异氧菌、甲烷菌、己酸菌、乳酸菌、硫酸盐还原菌、硝酸盐还原菌等。

The second part of research is analysis of the decolorization bacterial by anaerobic bioreactor, decolour experimental result: To decolour complete for 6 hour have 5 colonies, define for being high decolor bacterial; to decolour complete for 6~36 hour have 20 colonies, define for being medium decolor bacterial; And the person who greater thans 70% of decolouring rate have 25 colonies within 36 hours, define for being low decolor bacterial.

研究第二部份为厌氧脱色槽中之厌氧脱色菌种之分析，初步脱色实验结果为6小时内脱色完毕者有5株，定义为高脱色菌株；6~36小时内脱色完毕者有20株，定义为中脱色菌株；而在6~36小时内脱色率大於70%者有25株，定义为低脱色菌株。

The results indicate that (1) After acclimation and induction, Phosphorus Accumulating Organism not only has the characteristics of denitrification, but also has the characteristics of takeup phosphate in aerobic;(2) Denitrifying phosphate accumulating bacteria using NO3- as electron acceptor indeed existed in the conventional enhanced biological phosphorus removal system;(3) The facultative anaerobe seperated during the process of acclimation are Corynebacterium, Pseudodiphtheria corynebacterium, Staphylococcus and Moraxella; all of which can be functioned as denitrifying phosphorus accumulating to various degree.
