摘要：
The treatment of domestic and industrial wastewater is one of the major sources of CH4in the Chinese waste sector. On the basis of statistical data and country-specific emission factors, using IPCC methodology, the characteristics of CH4emissions from wastewater treatment in China were analyzed. The driving factors of CH4emissions were studied, and the emission trend and reduction potential were predicted and analyzed according to the current situation. Results show that in 2010, CH4emissions from the treatment of domestic and industrial wastewater were0.6110 Mt and 1.6237 Mt, respectively. Eight major industries account for more than 92% of emissions, and CH4emissions gradually increased from 2005 to 2010. From the controlling management scenario, we predict that in 2020, CH4emissions from the treatment of domestic and industrial wastewater will be 1.0136 Mt and 2.3393 Mt, respectively, and the reduction potential will be 0.0763 Mt and 0.2599 Mt, respectively.From 2010 to 2020, CH4emissions from the treatment of domestic and industrial wastewater will increase by 66% and 44%, respectively.
