Based on the relevant theories of life cycle assessment,this study takes the main greenhouse gases CH4,N2O and CO2 produced in the process of industrial wastewater treatment as the research object,and establishes the carbon emission accounting model including wastewater treatment,sludge treatment and sludge disposal.The model calculation is also studied.The study shows that the largest greenhouse gas emission link is the wastewater treatment link,and the indirect carbon emissions caused by electricity consumption account for more than 90%of the carbon emissions in this link.The second is the sludge disposal link,and the sludge treatment link accounts for the smallest proportion.The model can provide reference for carbon emission accounting of industrial wastewater treatment in related industries.
