摘要
以某污水处理厂为例,将温室气体碳排放源划分为直接排放和间接排放,基于实测法和排放因子法,核算污水处理、污泥处理、污泥外运处置三个阶段碳排放情况,并对该过程中减碳潜力及成本进行了评估分析.结果表明:该污水处理厂碳排放量为3137.58 t,碳补偿量为149.60 t,净排放量为 2987.98 t;电能消耗是本项目的最大碳排放源,具体可通过分布式光伏、购买绿电或购买绿证三种方式实现零碳电力消费;从全生命周期成本考虑,餐厨协同厌氧消化+土地利用和好氧堆肥+土地利用两种处置方式成本接近,且远低于焚烧+建材利用处置成本.
Abstract
The greenhouse gas emissions from a certain sewage treatment plant were divided into direct emissions and indirect emissions.Carbon emissions in the three stages of sewage treatment,sludge treatment,and sludge disposal were calculated with the methods of actual measurement and emission factor.Carbon reduction potential and cost were analyzed then.The result showed that the carbon emissions of this sewage treatment plant were 3137.58 tons,carbon compensation was 149.60 tons,and net emissions were2987.98 tons.Electricity consumption is the largest source of carbon emissions in this project.Specifically,zero-carbon electricity consumption can be achieved through distributed photovoltaics,purchase of green electricity or purchase of green certificates.The cost of kitchen co-anaerobic digestion&land use and aerobic composting&land use is relatively close,and far lower than the cost of incineration&building materials utilization.
