摘要

摘要: 城市污水处理厂作为人类温室气体的主要来源之一,其碳排放量逐渐受到关注,以贵阳市4座下沉式再生水厂为例,核算其碳排放强度和影响因素。4座再生水厂均为倒置A²/O(厌氧段-缺氧段-好氧段)脱氮除磷处理工艺。将再生水厂运行阶段碳排放分为直接碳排放[主要包括甲烷(CH₄)和氧化亚氮(N₂O)直接排放]和间接碳排放(能耗碳排放及物耗碳排放)。根据混合的碳排放系数,核算出2022年碳排放强度为0.579~0.781 kg CO₂/m³,碳排放贡献变化顺序为能耗(62%~69%)>去除TN产N₂O(15%~23%)>物耗(12%~16%)>去除COD产CH₄(2%~3%)。影响再生水厂碳排放的因素包括处理规模、实际污水处理量、进出水水质、能源消耗类型、运行工况等,因此,管理人员应对污水处理厂实行精细化管理,根据进水水质水量调整污水处理厂大功率耗电设备的使用及药剂的投加,推动污水处理厂节水节能和碳减排协同的低碳管理。

Abstract: Urban wastewater treatment plants (WWTPs), as one of the main sources of human greenhouse gas emissions, have gradually attracted attention. In this paper, four reclaimed water plants in Guiyang were taken as the case to calculate carbon emission intensity and influencing fuctors. All the four plants adopt the inverted A²/O (anaerobic-anoxic-oxic) denitrification and phosphorus removal process. The carbon emissions during the operation stage of reclaimed water plants were divided into direct carbon emissions and indirect carbon emissions. Direct carbon emissions include methane (CH₄) emissions and nitrous oxide (N₂O) emissions, while indirect carbon emissions include energy-related carbon emissions and material-related carbon emissions. Based on the mixed carbon emission coefficient, it was calculated that the carbon emission intensity in 2022 ranges from 0.579 kg CO₂/m³ to 0.781 kg CO₂/m³, and the contribution of carbon emissions was in the order of energy consumption (62%~69%)>greenhouse gas N₂O produced by TN reduction (15%~23%)>material consumption (12%~16%)>greenhouse gas CH₄ produced by COD reduction (2%~3%). Carbon emissions factors of reclaimed water plants include treatment scale, actual sewage treatment capacity, post-treatment water quality requirements, energy consumption type, operating conditions, sludge dewatering methods, etc. Therefore, the management personnel of the sewage treatment plant should implement fine management, adjust the use of high power consumption equipment and the dosage of chemicals according to the influent quality and quantity, to promote the low-carbon management of water, energy conservation and carbon emission reduction of the reclaimed water plants.
