“双碳”背景下潍坊市水系统碳排放核算与碳减排研究
- Title:
- Research on Carbon Emission Accounting and Carbon Emission Reduction of Water System in Weifang under “Dual-carbon” Background
- 摘要:
- 在“双碳”背景下，碳排放和碳减排受到越来越多的关注。城市水系统是城市主要碳排放源之一，在取水、输送、用水等过程中都会产生大量碳排放，因此有必要对城市水系统整个过程及各个环节碳排放进行研究分析。本文以潍坊市水系统为例，构建了城市水系统碳排放理论研究框架和方法，核算了水系统各个环节的碳排放量，分析了不同环节碳排放特征和影响因素，并从节水节能机制、低碳设计、管网布局等方面提出了碳减排的措施和建议。结果表明，在城市水系统各个环节碳排放中，用水系统碳排放量>给水系统碳排放量>取水系统碳排放量，占比分别为89.64%、8.28%、2.08%，居民生活用水碳排放量最大，占整个水系统碳排放的50.84%，工业用水碳排放次之，占整个水系统碳排放量的25.84%。
- Abstract:
- In the context of “dual-carbon”, carbon emissions and carbon reduction have received more and more attention. Urban water system is one of the main sources of urban carbon emissions, and a large amount of carbon emissions will be generated in the process of water intake, transportation and water use, etc.. It is necessary to study and analyze the carbon emissions in the whole process and each link of urban water system. Taking the water system of Weifang as an example, this paper systematically constructed the theoretical research framework and method of carbon emissions for urban water system, calculated the carbon emissions of each link of the water system, analyzed the carbon emission characteristics and influencing factors of different links, and put forward carbon emission reduction measures and suggestions from the aspects of water-saving and energy-saving system mechanism, low-carbon design, pipe network layout and other aspects. The results indicate: in terms of carbon emissions in each link of urban water system, carbon emissions from water use system > carbon emissions from water supply system > carbon emissions from water intake system, accounted for 89.64%, 8.28% and 2.08% of carbon emissions in the whole process, respectively. Carbon emissions from residential water use were the largest, accounting for 50.84% of carbon emissions in the whole water system, followed by carbon emissions from industrial water. It accounts for 25.84% of the carbon emissions of the whole water system.
