摘　　要：针对北方冬季城市污水处理厂低温运行难以保证出水水质达标这一难题,结合当前国内外研究现状综述了低温是如何影响活性污泥沉降性能、有机物去除效率、脱氮除磷效率及微生物种类变化的研究成果,总结了现行低温城市污水活性污泥系统的运行改进措施,指出了提高低温城市污水处理效率的发展方向。Aiming at a puzzled problem of hard operation to polluted water treatment in urban sewage plant by low temperature affected by the northern winter whether,and combining with the domestic and overseas studies, this paper reviews some properties related activated sludge under the situation of low temperature, such as properties of settlement, the removal efficiency of organic matter, the nitrogen and phosphorus effi- ciency,and the changes of microbial species. It sums up some improvement measures of low temperature sewage activated sludge system running,and points out the temperature development direction on how to improve the efficiency of urban sewage treatment.
