Research and application of carbon reduction technology in municipal wastewater system under double carbon background
Municipal wastewater system produces a large amount of greenhouse gases.Carbon emission of different links in the wastewater system such as source collection,wastewater treat-ment,sludge treatment and disposal was systematically analyzed.To promote the pollution reduc-tion and carbon reduction of wastewater system,carbon reduction technologies such as source qual-ity improvement and carbon reduction,renewable water resources and wastewater heat sources re-covery,and sludge high-value utilization are proposed,based on the properties of resource and en-ergy from the perspective of engineering application and implementation.Also,engineering pro-jects achieved scale benefits of carbon reduction through the application of above technologies.Fur-thermore,top-level design should be done scientifically and carbon reduction technology should be selected according to local conditions to reduce direct and indirect carbon emissions in the process of construction and renovation of wastewater facilities.
