摘　　要：叙述了低温对硝化效果的影响和低温对硝化微生物的作用机理,低温下污水生物处理过程中硝化效率显著下降,从而影响出水水质。总结了国内外提高低温硝化效果的强化措施,并指出未来可从低温酶活响应机制、多领域交叉研究及AOA古菌等方面着手研究低温硝化。Here, we introduce the mechanism of low temperature effect on nitrification and nitrification microorganism. Under low temperature condition, nitrification efficiency of wastewater biological treatment decreased obviously, which affect the effluent quality. The domestic and overseas intensifying measures on nitrification at low temperature are fully summarrizexl. And it＇s pointed out that the future study of biological nitrogen removal at low temperature should be worked on response mechanism of enzyme activity under low temperature, multidisciplinary crossover study and AOA archaea and so on.
