摘　　要：在“双碳”战略背景下,有效地核算污水处理厂碳排放量对节能减碳具有重要意义。基于“水-能-碳”关联系统,构建新型核算体系,并以长江中下游某城镇污水厂为案例,开展碳排放量核算。结果表明,常规情况下污水厂碳排放总量达208211.97 kgCO_(2)/d,直接碳排放为主要排放源,各子碳排放系统中CH_(4)类碳排放量占比最高,达48.26%。最后,针对核算结果,提出污水处理厂减碳措施与建议,以期为后来的研究者、工程技术人员研究同类问题提供参考。Under the background of“double carbon”strategy,effective accounting of carbon emissions from sewage treatment plants is of great significance for energy saving and carbon reduction.This paper constructs a new type of accounting system based on the"water-energy-carbon"correlation system,and takes a sewage plant in a town in the middle and lower reaches of the Yangtze River as a case study to carry out carbon emission accounting.The results show that the total carbon emissions of the sewage plant under normal circumstances amounted to 208211.97 kgCO2/d,with direct carbon emissions as the main source of emissions,and the proportion of CH4 carbon emissions in each subcarbon emission system is the highest,amounting to 48.26%.Finally,for the accounting results,carbon reduction measures and suggestions for the wastewater treatment plant are proposed,in order to provide reference for later researchers,engineers and technicians to study the same kind of problems.
