摘　　要：基于排放因子法对四甲基氢氧化铵(TMAH)废水处理方案进行碳核算。结果显示:电耗为TMAH废水处理碳排放的主要贡献因素。TMAH废水处理方案中,电耗的间接碳排放量最大,占48.31%;N_(2)O的直接碳排放量最小,占11.96%。在电耗碳排放过程中,泵的碳排放量占比最大,为65.73%;其次是曝气机,为18.81%。在药耗碳排放过程中,碳排放量排序为聚合氯化铝(PAC)>硫酸亚铁>草酸>聚丙烯酰胺(PAM)>尿素>浓硫酸。碳减、碳补偿优化后,总碳排放量降低了62.45%,碳补偿量明显高于碳减量。Conducting a carbon accounting of the TMAH(tetramethylammonium hydroxide)wastewater treatment solution based on the emission factor method,concluding that electricity consumption is the main contributing factor to carbon emissions.Among the entire treatment solution for TMAH wastewater,indirect carbon emissions from electricity consumption accounted for the largest proportion,reaching 48.31%,while direct emissions of N_(2)O contributed the least,accounting for 11.96%.During the entire process of carbon emissions from electricity consumption,pumps accounted for the largest proportion of carbon emissions,at 65.73%,followed by aeration devices at 18.81%.Among the carbon emissions from chemical consumption,the order was PAC(polyaluminum chloride)>ferrous sulfate>oxalic acid>PAM(polyacrylamide)>urea>concentrated sulfuric acid.After optimizing carbon reduction and carbon compensation,the total carbon emissions of the entire solution were significantly reduced by 62.45%,and the amount of carbon compensation was significantly higher than the amount of carbon reduction.
