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208 211.97 kgCO2/d,直接碳排放为主要排放源,各子碳排放系统中CH4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.
Abstract
Under the background of"double carbon"strategy,effective accounting of carbon emissions from sewage treat-ment 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 208 211.97 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 high-est,amounting to 48.26％.Finally,for the accounting results,carbon reduction measures and suggestions for the wastewa-ter treatment plant are proposed,in order to provide reference for later researchers,engineers and technicians to study the same kind of problems.
