摘　　要：碳中和背景下,污水处理厂不仅要实现水资源的可持续性,还要实现碳减排。若在污水处理过程中对污水中潜在的化学能和热能进行回收利用,则可弥补污水处理厂运行中的能量损耗,甚至达到碳中和的目标。为探明污水处理厂实现碳中和的可行性,通过对国内外污水处理厂实现碳中和案例的解读分析,总结了实现碳中和目标的实施途径和主要减排工艺,并提出了碳中和视角下我国未来污水处理厂所面临的技术挑战和研究方向。Under the background of carbon neutrality,sewage treatment plants are required not only to achieve the sustainability of water resources,but also to achieve carbon emission reduction.If the potential chemical energy and heat energy in sewage are recycled in the process of sewage treatment,it can make up for the energy loss in the op⁃eration of sewage treatment plant,and even achieve the goal of carbon neutralization.In order to find out the feasibil⁃ity of carbon neutralization in sewage treatment plants,through the interpretation and analysis of the cases of carbon neutralization in domestic and foreign sewage treatment plants,the implementation approaches and main emission reduction processes for achieving the goal of carbon neutralization were summarized,and the technical challenges and future research directions for future sewage treatment plants in China from the perspective of carbon neutraliza⁃tion were put forward.
