Abstract

Under the background of carbon neutralization, carbon neutralization in sewage treatment industry is paid more and more attention to by people. This study summarizes the main emission sources of greenhouse gases in the process of sewage treatment in China, including the direct emission sources of aerobic respiration of sewage treatment microorganisms, nitric oxide produced by nitrification and denitrification, and the indirect emission sources of motors and pumps required in the process of sewage treatment. This study focus on the emission sources of greenhouse gases in the process of sewage treatment and the problems faced by the current sewage treatment technology, summarizes the methods and technical development direction of carbon neutralization in China's sewage treatment plant, including "energy substitution and technology improvement ", "carbon dioxide capture and storage", "sludge cogeneration", "development of new low-energy sewage treatment processes such as short-range nitrification anaerobic ammonia oxidation". It is expected to provide reference and guidance for China to reduce greenhouse gas emissions in the field of sewage treatment and finally achieve the energy conservation and emission reduction goal of carbon neutralization.
