May I ask you said the dump leak detection equipment, this is what kind of equipment, not before which dump in the country with.

Wuhan Geotechnical Institute of solid waste disposal and geosynthetics testing has accumulated a wealth of experience in research and development and detection, has as the presiding unit of the National 973 Program, 863 Program, Twelfth Five-Year Plan, the National Natural Science Foundation, the Hubei Provincial major scientific and technological research and major equipment special projects, as well as engineering projects such as more than 20, condensed the formation of a number of national standards and industry technical specifications related to the solid waste disposal (including editing the first domestic "domestic waste landfill", "the leakage detection equipment", "the leakage detection equipment"). It has condensed and formed a number of national standards and industry technical regulations related to the safe disposal of solid wastes (among which, it has edited the first "Technical Regulations for the Detection of Leakage and Damage of Geomembrane for the Prevention of Seepage of Domestic Landfills" (CJJ/T214-2014)), and won the first prize of Hubei Provincial Scientific and Technological Advancement (in the direction of solid wastes) in 2006 and 2012, respectively.

With international advanced solid waste landfill leakage pollution environment detection technology and detection equipment - LM-cersm leakage detection system, the system by the Wuhan Institute of Geotechnical Research combined with the domestic landfill seepage control engineering construction quality testing and landfill leakage damage hole detection independently researched and developed, all using imported components, with high detection precision, high accuracy, good performance and high quality. All components are imported from Europe, featuring high detection accuracy, stable performance and strong timeliness.

Detection of the equipment used in the LM-cersm-O measuring frame leakage pinpointing system is mainly used for solid waste landfill artificial seepage control system seepage control construction quality testing and acceptance of the work, the equipment for the recent years the common use of the two-electrode method of the "upgraded version" --- dipole method. Wuhan Geotechnical Research Institute independent research and development, Europe imported components of fixed-pitch vein porcelain electrode, electrode filled with copper sulfate solution pentahydrate, to solve the ordinary two-electrode method of metal detection electrode easy polarization, measurement error and other shortcomings, to eliminate the leakage of measurement, misdiagnosis occurs (the relevant invention patents have been declared). Through the high-voltage generator to the landfill seepage control geomembrane on the gravel guide layer and the external earth power supply, HDPE membrane has any leakage breakage will have the current through the LM-cersm-O mobile measuring frame through the leakage breakage of the vicinity of up to 2 meters, will be recorded in detail due to the breakage of the HDPE membrane caused by the electrical potential anomaly. By walking less than 1 meter apart and analyzing the data, it is possible to accurately locate leakage damage holes of no less than 6mm.

At present, hundreds of landfills in the international (South Korea, Indonesia), domestic (Zhanjiang, Guangdong, Guangxi Laibin, Nanjing, Jiangsu, Nantong, Jingjiang, Zhejiang Jinhua, Wuhan, Hubei, Yichang, Wufeng, etc.) have applied the equipment to landfills to carry out the quality of construction of landfill containment layer and seepage breakage detection technology services.
