摘　　要：【目的】在我国生态文明建设的大背景下,污水处理行业不仅是打好污染防治攻坚战的关键环节,也是温室气体减排的重要领域。因此,明确污水处理厂的碳排放状况,并实施低碳化改造,对于应对气候变化、推动可持续发展至关重要。研究旨在通过科学的方法和实际案例,探索污水处理厂的低碳化改造路径,为未来污水厂的节能减排工作提供了经验和启示。【方法】研究基于国内现有的碳核算理论框架,选取福建某具有代表性的污水处理厂作为研究对象。利用福建某污水处理厂日处理量、进出水指标、污泥产量、耗电量及药剂消耗量等数据对该污水厂的直接碳排放和间接碳排放进行碳排放核算。通过分析该水厂污水处理碳排放核算结果,因地制宜综合厂区地理位置及周边资源,提出了更换低碳碳源药剂、调节运行参数降低碳排放、优化变频调节设备降低功率、光伏改造能源利用4条减碳措施。【结果】经过一系列低碳化改造并稳定运行8个月后再次进行碳排放核算,该污水处理厂的碳排放强度得到了显著降低。其碳排放强度由改造前的0.7650 kg CO_(2)/m^(3)下降至0.7104 kg CO_(2)/m^(3),取得了显著的环保效益。【结论】污水处理低碳运行应以微观低碳机理为抓手,通过调节运行参数等手段,辅以新能源发电的使用,共同推动污水处理行业向更加低碳、环保的方向发展。[Objective]Against the backdrop of ecological civilization construction in China,the wastewater treatment industry is not only a crucial link in the battle against pollution prevention and control but also a significant area for greenhouse gas emission reduction.Therefore,clarifying the carbon emission status of wastewater treatment plants(WWTPs)and implementing low-carbon retrofits are vital for addressing climate change and promoting sustainable development.[Methods]This study aimed to explore the pathways for low-carbon retrofits of WWTPs through scientific method and practical cases,providing experience and insights for future energy conservation and emission reduction efforts in wastewater treatment.Based on the existing domestic carbon accounting theoretical framework,a representative WWTP in Fujian Province was selected as the research object.Data such as daily treatment capacity,influent and effluent indices,sludge production,electricity consumption,and reagent consumption from the WWTP in Fujian were utilized to conduct carbon emission accounting for both direct and indirect carbon emissions.By analyzing the carbon emission accounting result of the WWTP′s wastewater treatment process,and considering the WWTP′s geographical location and surrounding resources,four carbon reduction measures were proposed:Replacing low-carbon carbon source agents,optimizing operational controls e.g.areation control,enhancing frenquency conversion control,and transforming photovoltaic energy utilization.After a series of lowcarbon retrofits and eight months of stable operation,carbon emission accounting was conducted again,revealing a significant reduction in the carbon emission intensity of the WWTP.[Results]Specifically,its carbon emission intensity decreased from 0.7650 kg CO_(2)/m^(3) before the retrofits to 0.7104 kg CO_(2)/m^(3) after,achieving notable environmental benefits.[Conclusion]Low-carbon operation in wastewater treatment should focus on micro-level low-carbon mechanisms,leveraging adjustments to operationa
