摘　　要：废弃物处理温室气体排放的主要排放源之一为废水(生活污水和工业废水)处理CH_4排放。根据统计资料和IPCC提供的方法,选择适合中国的排放因子,分析了中国废水处理2005—2010年的CH_4排放特征和2000—2010年CH_4产生的各驱动因子。并且根据中国的实际情况预测和分析了中国废水处理CH_4排放趋势和排放潜力。结果显示:2010年中国生活污水处理CH_4排放量为61.10万t,工业废水处理的CH_4排放量为162.37万t,造纸等八大行业CH_4排放量达到总CH_4排放量的92%以上,2005—2010年的CH_4排放量逐年增加;到2020年在减排情景下,生活污水处理CH_4排放量为101.36万t,减排潜力为7.63万t,比2010年排放量增加了66%工业废水处理CH_4排放量233.93万t,减排潜力为25.99万t,比2010年排放量增加了44%。The treatment process of domestic wastewater and industry wastewater is one of strong CH4 sources in waste treatment.According to the statistic data,IPCC model,and China local special emission factors,the characteristics of CH4 emissions from the wastewater treatment process were predicted analyzed.The driven factors of the CH4 emissions were also analyzed.And CH4 emission trend and potential were predicted and analyzed according to the current situations of China wastewater treatment.The results show that CH4 emissions from the treatments of domestic wastewater and industry wastewater is 611.0 thousand and 1623.7 thousand t respectively in 2010.Of which,CH4 emissions of the eight major industries,accounting for more than 92%.And the emission increased gradually from 2005 to 2010.If the scenario is under the controlling management in 2020,the CH4emissions from the treatments of domestic wastewater and industry wastewater will be 1.0136 and 2.3393 million t,respectively.The emission reductions potential will be respectively 0.0763 and 0.2599 million t,the CH4 emission from the treatments of domestic wastewater and industry wastewater will increase by 66%and 44%respectively relative to 2010.
