- Abstract:
- Not only has China not carried out independent research on greenhouse gas inventory of each sub-unit of urban sewage treatment, but there are also few studies on greenhouse gas estimation data of each sewage treatment system. Combined with the big data platform of “National Urban Sewage Treatment Information Management System” and guided by the goal of energy saving and emission reduction in urban sewage treatment industry, a comprehensive calculation model of energy saving and emission reduction in the whole process of sewage treatment was constructed. Variations in carbon emission of three sewage treatment plants before and after upgrading were calculated by the model and the critical controlling unit was identified. Appropriate raising sewage discharge standard could effectively reduce the carbon emission generated by each link of the sewage treatment plant, but further improvement of effluent standards would have an adverse effect on sewage treatment plants in terms of energy, resources and greenhouse gas emissions.
