摘要
调查某填埋场的填埋气收集现状,并进行现场抽气实验估算填埋气总产量,结果表明:全场填埋气总产量估算为42 416 m3/h,现场实际填埋气收集量约4 000 m3/h,填埋气收集率约为9.4%;扣除因填埋作业无法进行气体收集区域,有效收集面积内的产生量为14 138 m3/h,收集率为28.3%。针对现场填埋气收集率不高的问题,提出填埋气收集优化建议。
An investigation was launched about the conditions of landfill gas collection in one waste landfill site,and a landfill gas pump test on site was conducted to estimate the total generation capacity of landfill gas. The results showed that the total generation capacity by estimation of landfill gas was 42 416 m^3/h, about 4 000 m^3/h was collected in fact, the collection rate was 9.4%. Except the dumping active area where gas collection facilities could not be constructed, the total generation ca- pacity of landfill gas was 14 138 m^3/h in the effective collection area, and the collection rate was 28.3%. Aiming at low collection rate, some suggestions for improving landfill gas collection were presented.
