摘　　要：本文对缺氧生物滤池常温下处理城市污水的微生物特性进行了研究,结果表明,在反应器稳态运行条件下,微生物量沿填料层深度的垂直梯度明显;反应器内有机物降解主要遵循厌氧降解途径,参与降解过程的各类群微生物之间呈现良好的代谢平衡;硫酸盐还原菌不对产甲烷菌形成抑制。The study on microorganism characteristic of anoxic biofilter for municipal wastewater treatment at normal temperature is carried out, and the results is as follows: The biomass-gradient along media layer is obvious in steady-state reactor; The various microorganisms can keep good metabolism balance; and the inhibition of methane producing bacteria by sulfate reducing bacteria is not occurred; The degradation of the organic matte follows the way of anaerobic degradation.
