- 摘要:
- 2014年污水处理行业贡献的温室气体排放量占国家排放总量的比例接近1%，城镇污水处理厂作为国家重要的环保集中治污设施，亟待科学了解其污染治理活动与温室气体排放的关联性，在确保污染物去除的同时，通过对其温室气体关键排放点位的控制，明确其碳排放的核算边界和指标体系，量化核算与评价其温室气体排放量和排放强度。为此，优化了碳排放核算方式、明确产污参数与排放因子，并开展了处理流程的能（药）耗分析。从工艺设计、设备选型、精准控制、精细化运行等项目全周期环节，提出了系统性的减污降碳优化路径，旨在为污水处理厂的减污降碳、节能降耗协同增效提供参考。
- Abstract:
- The greenhouse gas emissions from the wastewater treatment industry accounted for nearly 1% ratio of the total national emissions in 2014. As crucial centralized facilities for achieving sewage purification targets and ensuring environmental protection, it is urgent to gain a scientific understanding of the relationship between WWTPs’ pollution control activities and greenhouse gas emission. Based on ensuring pollutant removal, through the control of greenhouse gas key emission points, it is necessary to establish a clear accounting boundary and index system for carbon emission in WWTPs to accurately quantify and evaluate their greenhouse gas emission and emission intensity. In this study, the carbon emission accounting method was refined and optimized, and the pollution production parameters and emission factors were clarified. An analysis of energy (chemicals) consumption throughout the entire treatment process has been conducted. Based on the entire cycle of WWTPs, including process design, equipment selection, accurate control, fine operation, a systematic optimization approach for pollution and carbon reduction has been proposed. This aims to offer practical insights into integrating pollution and carbon reduction efforts, as well as reducing energy and chemical consumption in WWTPs.
