Problems solved by technology

Usually the leachate is discharged through the pipeline designed at the bottom of the landfill, but because the pipeline is often silted up, the leachate cannot be discharged and accumulates, which seriously threatens the stability of the landfill. Currently, there are many causes of leachate A precedent for landfill destruction due to excessive height
The height of the leachate is one of the important parameters affecting the stability of the landfill. At present, there is no other convenient method for the height of the leachate except for on-site garbage excavation measurement and manual estimation.

Embodiment Construction

[0025] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0026] The leachate height monitoring device of domestic garbage landfill of the present invention, such as figure 1 As shown, it includes a ring electrode 1, an electric wire 2, a casing 3, a drainage blind ditch 4, and a high-density resistivity meter 5. The ring electrode 1 is bound on the annular groove of the sleeve 3, and the sleeve 3 is provided with an electric wire 2. After the wire 2 is electrically connected to each ring electrode 1, it passes through one end of the sleeve 3 and is electrically connected to a high-density resistivity Instrument 5, and sleeve pipe 3 is enclosed within in the plastic drainage blind ditch 4.

[0027] The ring electrode can be a closed ring copper wire, or an unclosed C-shaped copper wire, so that it is convenient to be clamped on the horizontally distributed ring groov...

Abstract

The invention discloses a leachate height monitoring device for a domestic waste landfill, and the device provided by the invention comprises annular electrodes, a drive pipe and a high-density resistivity instrument, wherein the drive pipe vertically extends into the waste landfill and is horizontally provided with annular grooves at intervals; the annular electrodes are arranged in the annular grooves; and an electric wire is electrically connected with the annular electrodes, extends out of the drive pipe and is electrically connected to the high-density resistivity instrument arranged outside the waste landfill. By utilizing the leachate height monitoring device for the domestic waste landfill, the effects of real-time monitoring, low cost, convenience and fastness can be achieved, and the problems of high measuring cost and long cycle after excavation of the traditional waste can also be solved.

Description

technical field [0001] The invention relates to leachate monitoring equipment, in particular to a device for monitoring the height of leachate in domestic waste landfills. Background technique [0002] With the rapid development of my country's economic construction, a large amount of domestic waste needs sanitary landfill, which requires the construction of a large landfill. In the landfill, domestic waste gradually degrades over time, producing leachate, and rainwater infiltrates into the waste body, causing a sharp increase in leachate. Usually the leachate is discharged through the pipeline designed at the bottom of the landfill, but because the pipeline is often silted up, the leachate cannot be discharged and accumulates, which seriously threatens the stability of the landfill. Currently, there are many causes of leachate There is a precedent for landfill damage due to excessive height. The height of leachate is one of the important parameters affecting the stability...
