摘要
Abstract
The study aimed to analyze the generation and diffusion patterns of marsh gas(landfill gas)in landfills after zero landfill of primary waste,and provided data and method references for future scientific management.Using statistical pre-diction,mutation test,ordered clustering,and spatial interpolation analysis methods,the original waste after"zero landfill"were used to analyze the annual changes,phased changes,and spatial diffusion patterns of landfill gas.The results showed that the original waste after"zero landfill"at the Gao'antun landfill will still be produced a certain amount of landfill gas for a considerable period of time.The annual and monthly variation patterns of landfill gas showed an overall downward trend,but the upward and downward fluctuation characteristics were obvious.The utilization and treatment of landfill gas were mainly concentrated in the first 20 years.Afterwards,the comprehensive utilization of the production volume of less than 50000 m3 was rarely studied.Through spatial analysis,it was found that the maximum diffusion range of landfill gas has been about 1.2 km,and it gradually decreased to within 0.3 km.The research results can provide data support for the scale of biogas facilities,surrounding environmental monitoring,and subsequent scientific management of landfill sites after zero landfill of primary waste.关键词
