摘　　要：近年来,我国污水处理事业得到了大力的发展,污水处理厂污染物减排能力逐年提升。然而,污水及剩余污泥处理处置过程中温室气体的排放问题却没有得到应有的重视。本文系统阐述了城市污水处理厂温室气体的来源,并从污水处理工艺的选择、工艺运行参数的科学调控、剩余污泥的处理处置和资源化、处理水的回用等方面提出了温室气体的减排对策,从而为开展污水处理厂温室气体减排的研究及低碳运行的实践提供借鉴。In recent years,great development has been made in wastewater treatment,resulting in annual increase in pollutants reduction capability of wastewater treatment plants.However,little attention has been paid to the greenhouse gases（GHGs） generated during wastewater and excess sludge treatment and disposal processes.The sources of GHGs generated from municipal wastewater treatment plants were demonstrated.In addition,reduction strategies of GHGs were proposed based on the selection of wastewater treatment process,scientific regulation and control of operation parameters,and treatment,disposal and reclamation of excess sludge as well as recycling of effluent,to provide guidance for further research on GHGs reduction and low-carbon operation in municipal wastewater treatment plants.
