摘要 为确保寒冷地区污水生物处理系统的有效运行,分离出了6株高效冷适应微生物,并鉴定分别隶属于动胶菌属、气单胞菌属、黄杆菌属、微球菌属、芽孢杆菌属、假单胞菌属.混合耐冷菌在低温条件下COD去除效率比中温菌高出63.67%,以软性聚氨酯泡沫为载体固定高活性耐冷菌,用于内循环复合生物反应器(ICCBR).以生活污水为研究对象,通过12个月的试验室小试,考察了ICCBR对生活污水的处理效能,生态因子的影响,污泥的理化特性,及系统内的微生物生态.结果表明:ICCBR系统在冬季4~10℃条件下的COD平均去除率为85.79%,全年COD平均去除率为86.66%,系统出水COD低于60mg·L^-1,达到污水一级B排放标准.季节性的温度变化使得系统内的生物种类和数量发生变化,原后生动物的数量从夏季的110000±30000微生物·mL^-1污泥减少到冬季的35000±20000微生物·mL^-1污泥,生物膜重量也呈现出先增长后略有降低的趋势.
