- 摘要：为提高垃圾填埋场CH4收集系统的收集效率,减少CH4的排放,对广州某生活垃圾填埋场CH4收集效率和填埋堆体表面CH4释放速率进行了研究.研究表明:采用US-EPA一级动力学模型计算出2010年该填埋场理论CH4产量为7.22×107 m3,估算实际产量为(2.17~2.89)×107 m3,实际收集量为1.75×107 m3,实际收集量占估算实际产量的60.6%~80.6%.填埋作业面是填埋场主要的CH4排放源,年排放量为 0.175×107 m3,占实际收集量的10.0%.其中,陈垃圾作业面和新填垃圾作业面CH4的释放速率分别为4.17 mol·m-2·h-1和0.29 mol·m-2·h-1.
- Abstract：The collection efficiency and the emission rate of methane in a municipal solid waste landfill in Guangzhou were studied for improving the collection efficiency and reducing the emission of methane. The theoretical methane emission of 7.22×107 m3 were estimated by the US-EPA first order kinetics model, which corresponded to (2.17~2.89)×107 m3 of actual methane emission in 2010. In practice, 1.75×107 m3 of methane was collected, with the collection efficiency ranging from 60.6% to 80.6%. The operating area was the main emission source of methane, and the emission rate of methane was 0.175×107 m3·a-1 which accounted for 10.0 percent of total methane collected. The emission rates of methane in matured and fresh refuses were 4.17 mol·m-2·h-1 and 0.29 mol·m-2·h-1, respectively.
