摘　　要：为了对安达生态塘污水处理系统中细菌的季节性变化进行定性和定量分析,结合生态塘中水质条件和运行参数,分析安达生态塘系统中细菌随季节和工艺条件变化的波动性和分布规律.结果表明,季节性温度变化对厌氧塘入口处和兼性塘出口处细菌总数的影响不大,对兼性塘入口处细菌总数影响较大,同一季节生态塘中各处理单元细菌总数呈下降趋势;对3个时期种属组成相似性分析表明兼性塘中的细菌组成正随着水质条件和气候条件而动态变化.In order to investigate the relationship between the variation in bacterial community structures and the operating conditions of eco-pond process, functional bacteria distribution and shift during different seasons in Anda eco-pond were detected qualitatively and quantitatively. The results show that in Anda eco-pond, the amount of bacteria in the inlet of anaerobic pond and in the outlet of anoxic pond has little seasonal variation, but great seasonal variation occurrs in the inlet of anoxic pond. The amount of bacteria in one season decreases gradually from the inlet of anaerobic pond to the outlet of anoxic pond. And the analysis for similarity coefficient （Cs） of bacterial community in the different seasons indicates that water quality and season shift greatly affect the bacterial community structure and their transformation.
