摘　　要：在低温条件下对曝气生物滤池(BAF)的挂膜进行了研究,考察了温度对曝气生物滤池挂膜的影响。结果表明,水温是低温挂膜的重要影响因素,低温条件下挂膜应采取保温措施,防止管路冻结,且对进水加热升温以促进微生物的生长。对挂膜期间曝气生物滤池去除有机物和NH3-N的情况进行了分析。The film - forming condition of BAF in low temperature was researched. The influence of temperature on BAF film - growing was tested. The results showed that the water temperature was key factor of BAF film - forming in low temperature. Some measures must be taken to prevent the pipeline freeze. The inlet water should be heated to elevate temperature and promote microorganisms growth. The removal efficiency of organics and the NH3 - N from the BAF during the film - forming period was analyzed.
