基于CALMIM程序的典型填埋场甲烷释放规律分析
Analysis of methane emission of typical landfills based on CALMIM model
摘要
Abstract
By using the program CALMIM ( California landfill methane inventory model) , the meth-ane emission in three typical landfills of China ( Shanghai Laogang landfill, Hangzhou Tianziling land-fill and Xi’ an Jiangcungou landfill) were numerically simulated, and the influences of climate, vege-tation coverage and methane oxidation rates on emission of methane in landfills were analyzed. The re-sults show that methane emission amount in Jiangcungou landfill is obviously higher than that of Laogang landfill and Tianziling landfill, and methane emission amount of Laogang landfill in Shanghai is higher than that of Tianziling landfill in Hangzhou. Two seasonal factors are considered, including temperature and precipitation, without considering methane oxidation, the largest and smallest quanti-ties of methane emission amount of Jiangcungou landfill are in August and November, which are 94 kg/m3 and 65 kg/m3 respectively. But the largest and smallest quantities of methane emission of Tianziling landfill are in January and September, which are 14 kg/m3 and 6 kg/m3 respectively. The vegetation coverage can reduce the methane emission amount, but this tendency is not obvious. When the maximum methane oxidation rate equals to 50 μgCH4 gsoil -1 d-1 , methane emission amount with-out considering oxidation is 6. 36 times that of considering oxidation, and emission amount of methane is close to zero when the oxidation rate of methane is greater than 100 μgCH4 gsoil -1 d-1 .关键词
