摘　　要：从城市污水厂活性污泥中筛选出高效耐冷菌,经固定化处理后被用于净化寒冷地区的生活污水。结果表明:固定化耐冷菌的最适pH范围并未发生偏移;当水力停留时间为5h时,对COD的降解率较常规的活性污泥平均提高了约33%。High-efficient psychrophile were screened from activated sludge of urban wastewater treatment plant. After acclimation, they were used for treatment of domestic sewage in cold region. The result shows that the range of pH adapting to the immobilized psychrophile does not change ; the degradation rate of COD is about 33% more than that of conventional activated sludge at HRT of 5 h.
