摘　　要： 城镇垃圾填埋场沼气组分复杂,产气量不稳定,且现场场地、水电供应等条件受限,往往不适宜建设复杂的沼气净化处理装置。为此,以某垃圾填埋场为例,根据其沼气的基本特性及现场的实际情况,提出了就地制取压缩沼气这一合理利用垃圾填埋场沼气的有效途径,介绍了压缩沼气的生产工艺技术及相关重点设备,提出了关键技术问题的解决方案。实践证明:在垃圾填埋场就地制取压缩沼气,并依据需要采用合适的工艺技术路线加以利用,可有效降低生产成本,获取收益。一个沼气量为500m3/h的回收装置,相当于每年节约4 018t标准煤,减少6 000tCO2排放量。 A complicated biogas purification plant is not proper to be built at the landfill sites of towns or cities,where the unsteadily generated biogas is made up of complex components,and neither water nor electricity can be conveniently supplied.In view of this,this paper presents a case history of producing the compressed biogas at a landfill.Based on the basic characteristics of biogas and the actual situation there,the in-situ production of the compressed biogas is regarded as one of the most effective means of using landfill biogas.Its involved techniques and main equipments are introduced in detail and the solutions to the key technical difficulties are put forward herein.This successful case history demonstrates that the properly chosen techniques can help achieve a considerable profit by reducing the production cost.In conclusion,a biogas recovery plant with the capacity of 500 m3 per hour will help save 4018 tons of standard coal consumption and reduce 6000 tons of CO2 emission each year.
