摘要
The seed sludge and the anaerobic sludge for a two-phase anaerobic process that is used for the treatment of N-phenylglycinonitrile wastewater were analyzed by PCR-TGGE technology. Furthermore, the structural differences of the seed sludge and the anaerobic sludge were investigated and compared. Moreover, the Shannon diversity index, an important parameter for studying microbial community diversity, was calculated for each sample. The results showed that the sludge's microbial community structure was significantly different before and after domestication. The microbial species and structure in the different stages of a two-phase anaerobic reactor were also obviously different. The acidogenic sludge's diversity index was the highest. Finally, the sludge diversity index of the secondary methanogenic reactor was higher than that of the primary methanogenic reactor and its degradation efficiency of pollutants was also higher.
