摘要
目的研究城市垃圾填埋气体成分及产气规律。方法 通过深圳市玉龙坑垃圾填埋场现场抽气试验及理论计算。结果 场区内填埋气体含量分别为CH_4 62.2％,O_2 1.0％,CO_2 34.7％,其余气体2.1％;理想条件下填埋场的产气量为188.7m^3/t,垃圾产气率方程为R_i=21.5e^(-0.12i),并计算填埋场历年的产气量。结论 填埋场目前正处于产气高峰期,整个产气过程约持续30a才能达到稳定、无害化。
Study on the generation law of gases produced from municipal solid waste landfill site and their components have been conduct in Shenzhen city. The result showed that the landfill gases consisted of CH4, O2, CO2 and other gases, and the concentration of these gases were 62. 20%, 1.0%, 34.7% and 2.1% respectively. Under ideal conditions, the generation amount is 188.7m3/t, the generation rate equation is Ri=21.5e 0.12i, and the annual gas generation amount has also been calculated. Nowaday, the gas generation is on the peak, the whole generation process may be stable and harmless for about 30 years.
