Additionally，the intensity of GHG emissions has decreased by about 50% ，and the indirect GHG reduction benefits from pollutant reduction have increased by about 1.8 times.These findings imply that the improvement of facilities can help urban domestic wastewatetreatmentyieldmoreenvironmentalbenefits.Itisrecommendedtonhancetheuseofcleanenergyandcarbonrecoveryto improve the synergistic control capability of GHG and pollution emissions in the future.
