摘要:
对长沙市既有污水处理厂的碳排放情况开展评估分析，结果表明2021年度碳排放总量达36.56万tCO2-eq，间接排放量占比达到68.00%，其碳排放水平受处理工艺、排放标准、水处理电耗、污染物削减量等因素影响。基于此，从厂网一体化角度系统总结了减碳、替碳、碳汇三方面的综合降碳技术策略，并通过案例污水处理厂开展城市更新背景下既有老旧污水处理厂提标改造协同优化减碳的策略应用研究。通过量化分析，案例污水处理厂通过工艺仿真优化调整参数、植物固碳方案设计、尾水回用等典型控碳替碳措施，实现了12.21%的降碳优化，降碳后其碳排放水平低于国内同种工艺的平均值。
Abstract:
This article conducts an assessment and analysis of the carbon emissions of existing wastewater treatment plants in Changsha. The total carbon emissions in 2021 amounted to 365 600 tCO2-eq, with indirect emissions accounting for 68.00%. The carbon emission level is influenced by factors such as treatment processes, discharge standards, electricity consumption per ton of water, and pollutant reduction. Based on this, the article systematically summarizes the technical strategies for carbon reduction, carbon substitution, and carbon sinks from the perspective of wastewater treatment plant-drainage pipe network integration. A case study is also presented, focusing on the application of collaborative optimization carbon reduction strategies for the upgrading old wastewater treatment plants in the context of urban renewal. Through quantitative analysis, the case?study plant achieved a 12.21% optimization in carbon reduction by implementing typical carbon control and substitution measures. These measures included process simulation and parameter optimization, plant?based carbon sequestration scheme design, and tailwater reuse. After carbon reduction, its carbon emission level was lower than the average value reported of the same process in China.
