- Abstract:
- A large number of greenhouse gases (GHG) are produced during wastewater treatment, mainly including CO2, methane, N2O, etc. By 2030, the GHG emissions from the wastewater treatment industry in China will reach 2.95% of the national greenhouse gas emissions. Achieving low-carbon or zero-carbon emission is of great significance to complete the carbon emission peak and carbon neutralization. In order to effectively reduce GHG emissions from wastewater treatment plants, it is necessary to accurately evaluate the GHG emissions of each wastewater treatment facility. Referring to the Handbook on Global Warming Countermeasures for Sewage Treatment Systems issued by Ministry of the Environment of Japan, this paper introduced the sources of GHG, the emission calculation methods of GHG, and the emission reduction measures for each unit of wastewater treatment plants, which could provide suggestions for the calculation and emission reduction of GHG emissions from wastewater treatment plants in China.
