Embodiment Construction

[0011] The technical scheme of the present invention will be further described below in conjunction with accompanying drawing:

[0012] The Feicheng Coal Mine in Shandong Province has been mining since 1958. At present, the coal resources in the mining area are almost exhausted, and some mines have been closed. Under the support of the project of the Ministry of Science and Technology, the present invention is tentatively applied to the mine water treatment of Feicheng Coal Mine and achieves relatively satisfactory results. Before the coal mine is closed, the main roadway 1 in the shaft is sprayed, and a baffle 2 is built every 5m. After the pit was closed, the accumulated water in the roadway in the well in 2000 was 80,000m 3 , the daily water filling capacity is 8000m 3 / d. Suction pump 4 with a power of 1000kw (water pumping capacity 450m 3 / h) Raise the mine water to the ground, flow into the drug pool 7 (5m×5m×3m) along the surface channel, and put 5kg of oxidant soli...

Abstract

The invention discloses a processing method of waste well impoundment, which is characterized by the following: elevating well water to the ground through pump; injecting into path below well through drug pond with oxidizer, neutralizer and flocculant; removing oil, iron and acid; circulating water partially; filtering; proceeding electric dialysis; sterilizing; fitting for agriculture, industry and living water grade by grade.

Description

technical field [0001] The invention relates to a treatment method for mine water, and is especially suitable for the treatment of abandoned mine water containing suspended matter, iron, oil, acidity and high salinity. Background technique [0002] At present, according to the site location of the mine water treatment system, mine water treatment can be divided into surface mine water treatment and underground mine water treatment. [0003] Surface mine water treatment is to lift mine water (or old kiln water) to the ground through pumps, and after a series of processes such as aeration, flocculation, sedimentation, filtration, neutralization, desalination, and disinfection on the ground, the water produced The water quality meets the national industrial or drinking water standard. Although the treatment effect of this method is obvious and the operability is strong, the one-time investment is relatively large, the treatment facilities occupy a large area, and the treated w...
