摘要
生活垃圾填埋场的渗漏问题对周边生态环境和地下水安全构成严重威胁,造成土壤污染、地下水污染以及生态破坏等危害。等值反磁通瞬变电磁技术(OCTEM)具有浅层探测精度高、抗干扰能力强、工作效率高的特点,能够穿透垃圾堆体低阻覆盖层,实现填埋区结构分层以及渗漏区的准确判定。本文将OCTEM技术应用于生活垃圾填埋场渗漏探测,采用二维与三维反演相结合的处理解释方法,成功定位两处渗漏异常区,并经钻探验证其中一处,证实了该技术的实用性和有效性。研究结果表明,OCTEM技术能够有效识别填埋场中的渗漏位置,可为环境保护和污染治理提供科学依据。
The leakage problem of municipal solid waste landfills poses a serious threat to the surrounding ecological environment and groundwater safety,causing soil contamination,groundwater pollution,and ecological destruction,among other hazards.The Offset Controlled Transient Electromagnetic Method(OCTEM)is characterized by high accuracy in shallow detection,strong resistance to interference,and high work efficiency.It can penetrate the low-resistivity cover layer of the landfill and achieve accurate identification of the landfill structure and leakage zones.In this paper,OCTEM technology is applied to the detection of landfill leakage zones.Two-dimensional and three-dimensional inversions and interpretation techniques are combined to locate two anomalies caused by leakage zones successfully,one of which is verified by drilling.The results show that OCTEM technology can effectively identify leakage positions in landfills and provide a scientific basis for environmental protection and pollution control.
