长江经济带固废污染治理是长江生态环境保护修复攻坚战中的重要工作内容。为深入了解沿江省市固废的综合治理与碳排放情况,运用数据统计分析和模型预测等方法,对生活垃圾和市政污泥等典型固废的产生量特性、处理处置特征及其综合环境影响(以碳排放计)进行定量分析。结果表明,2022年沿江省市生活垃圾和市政污泥的产生总量分别约为1.05亿t和508万t,预计到2025年将分别达到1.22亿t和646万t。其中,江苏省产生总量最大,分别约为2585万t和174万t。下游地区的缺口最大,分别约为1320万t和163万t。焚烧是生活垃圾和市政污泥的主要处理方式,平均占比分别约为76.1%和77.8%。生活垃圾和市政污泥的碳排放总量分别达到2289万t和9021万t,单位排放强度分别约为0.24CO2-eqt/t和2.21CO2-eqt/t。结合长江经济带各省市生活垃圾及污泥的产生特性和碳排放强度情况,提出了优化管理建议,为推动长江经济带固废低碳处理处置提供了参考。

The management of solid waste pollution in the Yangtze River Economic Belt is crucial forthe ecological environment protection and restoration campaign. In order to gain a deep understanding ofsolid waste management and carbon emissions along the river, this study conducts quantitative analyseson the generation characteristics, treatment and disposal features, and comprehensive environmentalimpacts (in terms of carbon emissions) of typical solid wastes such as domestic waste and municipalsludge. The analyses are based on data from statistical analysis and model prediction methods. The re⁃sults indicate that in 2022, the total generation of domestic waste and municipal sludge in the provincesand cities along the Yangtze River was approximately 105 million tons and 5.08 million tons, respec⁃tively. It is projected to reach approximately 122 million tons and 6.46 million tons by 2025, with Jian⁃gsu Province having the largest total generation (approximately 25.85 million tons and 1.74 million tonsfor domestic waste and municipal sludge, respectively). The downstream areas showed the largest gaps(approximately 13.20 million tons and 1.63 million tons). Incineration is the primary disposal methodfor both domestic waste and municipal sludge, accounting for around 76.1% and 77.8% on average,respectively. The total carbon emissions from domestic waste and municipal sludge are estimated toreach 22.89 million tons and 90.21 million tons, respectively, with unit emission intensities of approxi⁃mately 0.24 CO t/ t and 2.21 CO t/ t. Based on the generation characteristics and carbon emissionintensities of domestic waste and municipal sludge in various provinces and cities along the YangtzeRiver Economic Belt, this paper proposes optimization management recommendations to promote low-carbon treatment and disposal of solid waste in the Yangtze River Economic Belt.
