Abstract

Abstract

Aerobic remediation technology for old MSW landfills has been widely used in China due to its reduction performance on methane gas, and is expected as an important technical means of landfill remediation under the background of China's Dual Carbon Goals. The carbon emission accounting models commonly used at home and abroad are difficult to represent the carbon emission reduction of landfill aerobic remediation process. In this paper, the aerobic restoration project of Tianjin Huaming landfill was taken as the research object, and the engineering mechanical properties of the landfill, biochemical properties of waste degradation, and biochemical properties of landfill leachate were analyzed within 300 days of aerobic restoration work since May 2019. Two principal components were obtained, and a regression model of methane concentration in the landfill was established using the principal components analysis. This model can analyze and predict the decreasing law of methane gas concentration in landfill bodies during aerobic restoration, and then calculate the methane reduction of landfill aerobic restoration compared with the traditional anaerobic sealing field. It provides a theoretical basis for the calculation of carbon emission reduction of landfill aerobic restoration, and can be applied to judge aerobic restoration process when landfill showes the characteristic value of methane concentration stabilization.
