摘　　要：低温是影响污水生化系统中微生物生长代谢及污染物去除的重要环境因素,在我国西部及北方等寒冷地区普遍存在10℃以下甚至更低水温的污水,低温大大降低了这些地区污水生化处理性能,为提高低温污水生化处理效果,在分析低温对水处理微生物的影响机理基础上,针对10℃以下城镇生活污水,综述了国内外对其污水运行参数调控、生物膜法强化处理、菌剂生物强化处理、MBR膜处理技术领域的研究和应用现状,并基于最新研究成果,对适用于低温污水处理的新工艺技术进行了展望,最后结合寒冷地区污水处理厂升温保温技术应用现状,提出了未来可结合采用水源热泵、建筑被动采暖以及风光发电等技术对污水进行升温保温,以期为寒冷地区污水处理厂的高质量建设和运营提供技术参考。Low temperature is an important environmental factor that affects the growth and metabolism of microorganisms and the removal of pollutants in sewage biochemical systems.In cold regions such as western and northern China,sewage with water temperatures below 10℃or even lower generally exists.Low temperature greatly reduces the performance of sewage biochemical treatment in these regions.To improve the biochemical treatment effect of low-temperature wastewater,The impact mechanism of low temperature on water treatment microorganisms has been analyzed,and summarized the research and application status of domestic and foreign sewage operation parameter regulation,biofilm enhanced treatment,bacterial agent Bioaugmentation treatment,and MBR membrane treatment technology for urban domestic sewage below 10 C.And based on the latest research results,prospects for new process technologies suitable for low-temperature sewage treatment are presented.Finally,combined with the current application status of heating and insulation technology in sewage treatment plants in cold regions,it is proposed that in the future,technologies such as water source heat pumps,passive building heating,and wind and solar power generation can be combined to heat and insulate sewage.The article aims to provide technical references for the high-quality construction and operation of sewage treatment plants in cold regions.
