危险废物贮存库防渗层网络化实时监测系统

The Real Time Leakage Detection Network in Hazardous Waster Impoundments

该文以两检测电极间充满渗出液时电阻发生突变的特点作为HDPE膜渗漏的判据,结合渗出液的化学成分来判断渗漏的种类,利用TC35I模块通过GSM网进入INTERNET进行数据的交换,实现了危险物贮存库渗漏的网络化监测,为各级环保部门的管理提供了科学的依据。利用HDPE膜的绝缘性,根据贮存库中电场分布特点,提出了偶极子的漏洞定位方法,成功地解决了漏洞定位的问题。并指出检测电压随着漏洞的大小、偶极子的间距、贮存库液体的电阻率、供电电压的增加而增加,随着偶极子距HDPE膜的距离、偶极子的移动方向到漏洞的距离、贮存库液体的深度的增加而减小。该方法为填埋场HDPE膜铺设过程中的施工验收提供了参考。

This paper,taking the sudden change of electric resistance(caused by the liquid between the electrodes)as indication of HDPE leakage,using TC35I model through GSM into INTERNET to exchange data,realizes leakage monitor in hazardous water impoundments.The authors bring forth a successful method of locating leakage and point out that the voltage of the electrometer increases as the size of the leakage,the interval between the dipole,the electric resistance rate of the water impoundment,and the supply power increase,and decreases as the distance between the dipole and HDPE model,the distance between the moving direction of dipole and the leaking spot,and the depth of the water in impoundment increase.This method will provide references for construction and quality control in laying HDPE liner in landfill and rationale for administration for environmental organizations of all levels.
