垃圾填埋场填埋气回收处理与利用

简单介绍了阿苏卫垃圾卫生填埋场的建设和运行情况,并对填埋场的垃圾成分和垃圾量进行了分析,得到该填埋场填埋气的实测组分.依据经典EPA产气模型对填埋场潜在填埋气产量进行了预测.结果表明,在2005-2039年的运行期间,预计该填埋场填埋气的平均产量约为33.7×106 m3/a.比较研究了填埋场填埋气的回收利用技术,指出并网发电是该填埋场填埋气的最佳利用方式.通过对填埋场填埋气发电项目进行的技术经济分析表明,该工程总投资为3 394×104元,项目年直接经济效益达230×104元.

Recovery and Utilization of Landfill Gas from Landfill Site

The construction and operation of Asuwei Waste Sanitary Landfill were briefed,the refuse components and refuse quantities analyzed,and the component of the landfill gas measured.Based on an EPA gas produce projection model,the gas output from Asuwei landfill will be about 33.7×(10~6 m~3/a) from 2005 to 2039. Different landfill gas recovery technologies were also compared and it is found that power generation by landfill gas is the best recovery utility contrary to other technologies.The technical and economical feasibility analysis shows that the total investment of landfill gas power generation project is 33.94 million yuan,and the annual direct economic benefit is 2.30 million yuan.
