摘　　要：冬季低温严重影响我国大部分地区的以生化法为主的污水厂的污水处理效率,难以实现达标排放,对环境负荷造成了严重的影响,低温(0～10℃)已经成为生物水处理领域目前面临的一大难题。综述了近年来低温废水处理技术的研究现状,总结了低温对活性污泥降解过程影响的理化指标,并以磁场强化好氧活性污泥、厌氧颗粒污泥处理低温废水为出发点,综述了活性污泥处理低温废水的研究进展,展望了活性污泥处理低温废水的发展前景,为进一步研究活性污泥处理低温废水提供理论指导。The efficiency of wastewater treatment plants based on biochemical methods in most parts of China is seriously affected at low temperature in winter,and it is difficult to achieve the standard discharge,which has a serious impact on the environmental load.Low temperature(0~10℃)has been a major problem in the field of biological wastewater treatment.The research status of wastewater treatment at low temperature in recent years were reviewed and the indicators of the effect of low temperature on the degradation process of activated sludge were summarized.In terms of wastewater treatment at low temperature by enhancement of aerobic activated sludge by magnetic field and use of anaerobic granular sludge,the research status of wastewater treatment at low temperature by activated sludge in recent years were reviewed and its trends were prospected,to provide theguidances for further research on wastewater treatment by activated sludge at low temperature.
