- Abstract:
- The greenhouse gas emissions from the wastewater treatment industry accounted for nearly 1% ratio of the total national emissions in 2014. As crucial centralized facilities for achieving sewage purification targets and ensuring environmental protection, it is urgent to gain a scientific understanding of the relationship between WWTPs’ pollution control activities and greenhouse gas emission. Based on ensuring pollutant removal, through the control of greenhouse gas key emission points, it is necessary to establish a clear accounting boundary and index system for carbon emission in WWTPs to accurately quantify and evaluate their greenhouse gas emission and emission intensity. In this study, the carbon emission accounting method was refined and optimized, and the pollution production parameters and emission factors were clarified. An analysis of energy (chemicals) consumption throughout the entire treatment process has been conducted. Based on the entire cycle of WWTPs, including process design, equipment selection, accurate control, fine operation, a systematic optimization approach for pollution and carbon reduction has been proposed. This aims to offer practical insights into integrating pollution and carbon reduction efforts, as well as reducing energy and chemical consumption in WWTPs.
