摘要
以上海市2家典型城镇污水处理厂Ⅰ和Ⅱ为例,核算近年来因直接排放和间接排放产生的碳排放量。污水厂Ⅰ和Ⅱ的碳排放主要来自于对N污染物的处理,分别占总碳排放的61.36%、46.18%;污水厂Ⅰ电耗产生的碳排放从2015年到2022年翻了一番,污水厂Ⅱ电耗产生的碳排放占比达45.20%。2家污水厂单位进水的总排放强度分别为1065.02、1110.26 g CO_(2)eq/m^(3),与国内某些厂相比属较高水平;与IPCC缔约国相比,2座厂人均碳排放强度分别为1.76、1.93 kg CO_(2)eq/人,属较高水平。此研究运用指南进行核算,有助于了解上海污水厂碳排放基本情况,进而细化核算方法、完善排放因子,是减污降碳、实施双控的基础工作。
Two typical urban wastewater treatment plants,ⅠandⅡ,in Shanghai were taken as examples.This study calculated the carbon emissions caused by direct and indirect discharges in recent years.The results showed that the carbon emissions of plants I andⅡmainly stem from the treatment of N pollutants,accounting for 61.36%and 46.18%of the total carbon emissions respectively.The carbon emissions generated by the electricity consumption of plant I doubled from 2015 to 2022,while the carbon emissions generated by plantⅡ's electricity consumption accounted for 45.20%.The total emission intensities per unit of water inflow of the two plants were 1065.02 and 1110.26 g CO_(2)eq/m^(3),respectively,which were relatively high compared to some domestic plants.Compared with IPCC contracting parties,the per capita carbon emission intensities of the two plants were 1.76 and 1.93 kg CO_(2)eq/person,respectively,indicating a high level.This study utilized guidelines to conduct the calculation,giving reference to the basic situation of carbon emissions from wastewater treatment plants in Shanghai.It further refined the accounting methods and improved emission factors,laying a foundation for reducing pollution and carbon emissions,as well as implementing dual controls.
