主　　题：Carbon neutrality Wastewater treatment Fossil CO_(2)emissions System boundaries Systematic thinking 

摘      要：Recently,every industry has been working to achieve carbon neutrality,and the wastewater sector is no ***,little research focuses on the carbon accounting of wastewater treatment and the roadmap to carbon ***,to systematically perform accounting,we provide a sketch that describes three boundaries of the wastewater system and propose that the carbon neutrality of the wastewater system is far beyond the plant ***,we identify the direct and indirect carbon emissions of wastewater *** addition to direct emissions of CH_(4) and N_(2)O,direct fossil CO_(2) emissions from wastewater treatment should be included in accounting to set accurate ***,the technologies that assist in achieving carbon-neutral wastewater treatment both within-thefence of wastewater treatment plants and beyond the plant boundary are *** measurements of energy recovery,resource recovery,and water reuse contribute to reaching this *** concepts of energy neutrality and carbon neutrality are *** wastewater treatment cases in energy self-sufficiency may not achieve carbon ***,resource recovery methods are encouraged,especially to produce carbon-based ***,the trend of preference for the decentralized sewage treatment system is pinpointed,and systematic thinking to set the urban infrastructure layout as a whole is advocated.
