Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Aiming at the current status of mine water treatment, that is, ground treatment is the main method, it occupies a large area, pollutes the environment, and is transported over long distances, while the idle goaf and abandoned roadways cause waste of resources. The device is arranged underground, and includes a natural self-purification mechanism, a primary filter mechanism, a COD detection mechanism, a drug-adding flocculation mechanism, a secondary filter mechanism, and a water supply mechanism. The COD detection mechanism detects the water quality of the filtrate in the primary filter mechanism The water inlet of the natural self-cleaning mechanism is the goaf entrance provided with the grid, and the water outlet is connected with the water inlet of the primary filter mechanism; the sewage outlet of the primary filter mechanism is connected with the back discha...

Abstract

The invention discloses a downhole treatment and reuse device and method for mine water. The device comprises a natural self-cleaning mechanism, a first filtering mechanism, a COD detection mechanism, a dosing coagulation mechanism, a second filtering mechanism and a water supply mechanism. The first filtering mechanism, the COD detection mechanism, the dosing coagulation mechanism, the second filtering mechanism and the water supply mechanism are arranged on a downhole abandoned roadway. Water quality tests of the filter liquor in the first filtering mechanism are performed by the COD detection mechanism. The device is arranged on the downhole abandoned roadway, the problem that mine water is lifted out from mines and the treated water is discharged into mines to be used again is avoided, and the defects of land occupation, pollution and long-distance pipelining and the like, when mine water is treated on ground, are overcome. The downhole space is utilized fully and the treated water can be used at downhole operation places directly, and the rest water can be discharged onto ground to be used. The device reduces the cost of borehole operation, saves resources, and is efficient and safe. The device can be suitable for treatment of mine water of coal mines with worked-out sections, and especially is suitable for treatment of high-mineralized mine water and high-suspended matter mine water.

Description

technical field [0001] The invention relates to a coal mine well water treatment technology, in particular to a mine water treatment and reuse device and method with a goaf. Background technique [0002] According to the characteristics of pollutants in mine water, mine water is generally divided into: conventional mine water, high salinity mine water, acid mine water and special polluted mine water; of course, there are also mine water formed by mixing various water qualities. High salinity mine water and high suspended matter mine water in coal mines are widely distributed in my country's mining areas. At present, most mine water treatment systems are built on the ground, and the treatment equipment for high salinity mine water and high suspended matter mine water is still dominated by traditional sedimentation and manganese sand filters, so there are backward processes and low efficiency. Disadvantages such as large footprint. The bigger problem is that the upgrading of...
