） Abstract： To find out the microbial diversity of actived sludges and the similarity of microbial community in different biological contact tanks, activated sludges in the aerobic tank and anaerobic tank of JiangXinZhou wastewater treatment plant in Nanjing city were collected
Cell cracking method based on SDS was used to extract the DNA in the activated sludges, then genomic DNA were acquired about 23 kilobase
Further analysis of DNA extracted was performed by PCR-DGGE
The result is described as follows: microbial species in two kinds of biological contact tanks are quite abundant,all microorganisms in the aerobic tank exists in the anaerobic tank
The similarity coefficient calculated by software Quantity One reaches 75
2%
More theoretical bisis is provided for prcessing strategy of wastewater treatment plants from the paper

好氧池的细菌全部存在于厌氧池中
结果表明：2个不同的生物处理池的微生物的种类都相当丰富
采用Quantity One分析软件计算的二者的相似性系数达到了75
