摘　　要：通过对粤西某大型污水处理厂碳排放特征进行研究,分析中其各类碳排放量及碳排强度,研究碳排放强度与处理工艺等相关关系。结果表明:粤西某污水处理厂的2023年碳排放总量为19312.49tCO_(2),碳排放强度为0.277kg CO_(2)/m^(3);污水处理厂中电耗带来的碳排放量占比最高,高达76.76%,是主要的降碳对象;不同污水处理工艺的碳排放强度具有明显差异,微孔氧化沟A^(2)/O-MBBR工艺的碳排放强度仅0.257kgCO_(2)/m^(3),远低于CAST工艺碳排放强度。By studying carbon emission characteristics of a large wastewater treatment plant in western Guangdong,the carbon emission and carbon emission intensity were analyzed,and the relationship between carbon emission intensity and treatment process was studied.The results show that total carbon emission of a wastewater treatment plant in western Guangdong in 2023 is 19312.49t CO2,and carbon emission intensity is 0.277kg CO2/m3;Power consumption has the highest proportion,up to 76.76%,which is the main carbon reduction object;The carbon emission intensity of different wastewater treatment processes has obvious differences,and carbon emission intensity of microporous oxidation ditch A2/OMBBR process is only 0.257kgCO2/m3,which is far lower than that of CAST process.
