污泥好氧堆肥主要微生物类群及其生态规律

重庆探讨了城市污水处理厂污泥好氧堆肥过程中，反应器内的主要微生物类群、特征以及与环境因子的关系。研究发现，污泥好氧堆肥过程是微生物与其周围环境因子（有机物、温度和pH值）相互影响和相互作用的结果，有机物和温度在污泥堆肥过程中是影响微生物类群结构变化的主导环境因子，pH值则显示出非主导性环境因子的特点，堆肥过程微生物数量的变化规律与污水生物处理过程中微生物变化是不同的。

Research on Main Microorganism Groups and Their Ecological Law im Aeration Sludge Composting Process

This paper emphatically probes into main microorganism groups and their characteristics in sewage sludge aeration composition system,and relationships between these groups and the environmental factors.Researches show that there exist interactions between microorganism groups and the environmental factors,such as organic matters,temperature and pH.Organic matters and temperature are two primary factors that effect on variations of microorganism groups. pH is a non-primary environmental factor.It is also found that microbial quantity variation curve in sludge composting process is different from that of in wastewater treatment process.
