基于水-能-碳视角的供水系统碳足迹分析
- Title:
- Carbon Footprint Analysis of Water Supply System Based on Water-Energy-Carbon Perspective
- 摘要:
- 本文根据城市供水系统工程项目类型构建了两种不同功能碳排放量化核算模型，并开展实际项目应用，在新建项目设计方案比选中同步实现量化分析。通过核算分析，运维阶段的碳排放量占全生命周期碳排放量的78.91%，其中电耗碳排放量占86.82%，药耗碳排放量占13.12%，是碳排放控制的重点。从处理工艺流程角度进行量化分析，送水泵房、取水泵房为主要的能耗碳排放单元，其净碳排放量分别占制水工艺段的51.91%、21.64%，为减碳的重点环节；模型应用案例水厂采取优选水泵、智慧化设计等典型减碳技术后，碳排放强度减少38.30%；在既有厂站设备更新项目中采用送水泵房碳排放历史数据与供水量、出厂平均水压以及原水pH进行多元线性回归分析，发现其碳排放强度与供水总量、出厂平均水压、pH等呈现显性相关。为进一步探究供水系统区域碳排放特点，本研究对南方某省自来水厂能耗进行核算评估及主要影响因素分析，结果表明，不同区域之间因地形、取水方式、供水方式、制水工艺不同而呈现显著的碳排放差异，自来水厂能源碳排放量与城市服务人口、供水规模、地区生产总值（GDP）、供水普及率等社会因素呈现显著性相关。
- Abstract:
- This study developed two quantitative accounting models for carbon emissions based on water supply system project types and applied them to practical projects. In the selection of new project designs, quantitative analysis was integrated to compare alternatives. The results revealed that the operational phase contributed 78.91% of total life-cycle carbon emissions, with electricity consumption (86.82%) and chemical consumption (13.12%) identified as key emission sources. From a process flow perspective, the delivery pump house and intake pump house were the primary energy-intensive emission units, accounting for 51.91% and 21.64% of net carbon emissions in the water treatment process, respectively, marking them as key nodes for carbon reduction. The application of these models enabled the case study waterworks to reduce carbon emission intensity by 38.30% through optimized pump selection and the integration of smart design. For the equipment upgrades of existing waterworks（water supply station）, a multiple linear regression analysis of historical carbon emission data from delivery pump stations, combined with water supply volume, average outlet pressure, and raw water pH, demonstrated significant correlations between carbon emission intensity and these variables. To explore regional carbon emission characteristics, energy consumption and influencing factors were evaluated for waterworks in a southern Chinese province. The results highlighted significant emission variations across regions due to topography, water intake methods, supply modes, and treatment processes. Additionally, energy-related carbon emissions in waterworks showed strong correlations with social factors such as the urban population served, water supply capacity, GDP, and water supply coverage rate.
