垃圾填埋场渗漏电学监测系统设计及室内模拟试验

根据垃圾场渗滤液渗入地下后引起的地下介质电性变化及对自然电位场的改变，设计了用于垃圾填埋场渗滤液渗漏的在线电学监测系统。该系统在垃圾场建设期布设于高密度聚乙烯膜下方，在垃圾场运行期可实时监测垃圾场渗漏与否、渗漏点的位置及数量、渗滤液形成的羽状体在地下的形态，以便及时采取措施防止渗滤液造成严重的地下环境污染。并通过室内模拟实验证实了不同渗漏情况下，地下介质分布的电性剖面不同，电剖面异常区和污染区的分布具有空间对应关系。该系统的设置是实现环保型、智能型垃圾填埋场的重要举措。

Design of online electricity monitoring system for landfill leakage and indoor simulation experiment

Based on changes in electric property of underground media and natural potential field caused by landfill leakage, an online electricity monitoring system is designed to detect the leakage. The system is laid beneath the HDPE membrane when the landfill is constructed. During the operation of a landfill, this system can monitor the occurrence of leakage, pinpoint the leakage location, estimate the numbers of the leakage, and detect the shape of leachate plume. As a result, timely measures can be taken to prevent the underground environment from further pollution. In addition, indoor simulation experiments prove that electric profiles differ on different conditions of leakage, i.e., abnormal zones of the profiles correspond with spatial distribution of polluted zones. Installation of this system will achieve an intellectualized sanitary landfill.
