摘要:
基于排放因子法，对江西某典型城镇给水厂2021年—2023年运行阶段的碳排放进行核算与分析。该给水厂三年内碳排放强度分别为0.188 4、0.171 0、0.171 8 kg/m3，其中外购电力碳排放占比为87.80%，是核心排放源；净水药剂的生产贡献为12.13%，以聚合氯化铝和次氯酸钠为主。碳排放呈现显著季节性特征，电力碳排放峰值出现在夏季（8月—9月），聚合氯化铝碳排放峰值与雨季高浊度原水（4月—5月）强相关。使用光伏系统后，2023年电力碳排放强度较2021年降低14.78%。对气候指标、供水指标与碳排放强度的相关性分析表明，电力消耗、原水浊度、降水量及气温是碳排放强度的关键驱动因素。碳减排潜力分析表明，案例水厂通过技术优化与清洁能源的使用，可减排约44%。
Abstract:
The carbon emissions of a typical urban water supply plant in Jiangxi Province during its operational period from 2021 to 2023 were calculated and analyzed using the emission factor method. The carbon emission intensity of the water supply plant over the three-year period was 0.188 4 kg/m3, 0.171 0 kg/m3, and 0.171 8 kg/m3, respectively. Of the total emissions, 87.80% were attributed to purchased electricity, making it the primary source of carbon emissions. The production-related emissions from water purification chemicals accounted for 12.13%, primarily due to polyaluminium chloride and sodium hypochlorite. Carbon emissions exhibited distinct seasonal patterns. The peak in electricity-related carbon emissions occurred during the summer season of August and September, while the peak in carbon emissions associated with polyaluminium chloride production was closely correlated with periods of high-turbidity raw water intake during the rainy season, particularly from April to May. Following the implementation of photovoltaic systems, the carbon emission intensity of electricity in 2023 decreased by 14.78% compared to 2021. Correlation analysis of climate indicators, water supply indicators, and carbon emission intensity revealed that electricity consumption, raw water turbidity, precipitation, and temperature were the primary driving factors influencing carbon emission intensity. Analysis of carbon emission reduction potential indicated that the case water supply plant could achieve an approximate 44% reduction in emissions through technological optimization and the adoption of clean energy.
