The research focuses on the water discharge treatment plant for heavy and ultra-thick oil recovery.The wastewater treatment process includes conditioning de-oil tank,inclined plate de-oil tank,two-stage dissolved air flotation device,walnut shell filter,cooling tower,two-stage AS-PACT process,dual sedimentation tank,and quartz sand filter.A method for accounting carbon emissions from heavy oil and super heavy oil produced water has been developed.The car-bon emission intensity of the external discharge plant is 3.78 kgCO2eq/m3,with indirect carbon e-missions accounting for 87.20％.This clarifies the key points of carbon emissions in the entire process of produced water treatment.Secondly,the study analyzes the indirect carbon emission in-tensity resulting from material,heat,and electricity consumption.It explores the energy-saving and carbon reduction path of the effluent treatment plant.
