Underground water LNAPL monitoring and intercepting system and method
The underground water LNAPL monitoring and intercepting system comprises an underground water monitoring well and a monitoring and intercepting assembly arranged in the underground water monitoring well, the monitoring and intercepting assembly comprises a well casing and a VOCs detector, and a hydrophilic oleophobic hard foam sponge rod is arranged in the well casing; a gap between the well casing and the inner wall of the underground water monitoring well is sequentially filled with quartz sand and an organic matter interception mixture from bottom to top, the organic matter interception mixture is formed by mixing the quartz sand subjected to oleophylic and hydrophobic modification and a biological oil dispersant, a VOCs detector for early warning is pre-buried in the organic matter interception mixture, and the VOCs detector is in wireless connection with client terminal equipment. The invention further provides an underground water LNAPL monitoring and intercepting method, on the basis of the hanging capillary action of the quartz sand subjected to oleophylic and hydrophobic modification, timely early warning, rapid intercepting and in-situ repairing of the LNAPL in the underground water under the condition of small leakage amount are achieved, it is avoided that the LNAPL continues to permeate in the stratum along with the underground water, the operation process is simple, and the method is suitable for large-scale popularization and application. And emergency treatment of key point underground water of petroleum and petrochemical enterprises is facilitated.
本发明公开了一种地下水LNAPL监测拦截系统，包括地下水监测井和设置于其内部的监测拦截组件，监测拦截组件包括井管和VOCs探测器，井管内部设置有亲水疏油硬泡海绵棒，井管与地下水监测井内壁之间的间隙内由下至上依次充填有石英砂和有机物拦截混合物，有机物拦截混合物由经亲油疏水改性过后的石英砂和生物消油剂混合而成，其内部预埋有用于预警的VOCs探测器，VOCs探测器与客户终端设备无线连接。本发明还提出了一种地下水LNAPL监测拦截方法，基于经亲油疏水改性过后石英砂的悬挂毛细作用，实现了对小泄漏量情况下对地下水中LNAPL的及时预警、快速拦截和原位修复，避免了LNAPL随地下水继续在地层中渗透，操作过程简单，有利于石油石化企业关键点位地下水的应急处理。
