Embodiment Construction

[0010] The technical scheme of the present invention will be further described below in conjunction with accompanying drawing:

[0011] 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 mine is closed, the designed water volume of the roadway in the mine is 80,000m 3 , the daily water filling capacity is 8000m 3 / d. For example, a water pump 4 with a power of 1000kw (water pumping capacity of 450m 3 / h) Raise the mine water to the ground, and flow into the drug pool 7 (5m×5m×3m) along the surface channel. According to the water quality composition and concentration of the mine water designed and mined, 5kg of oxidant chlorine dioxide solids, neutralizer Limestone 50kg and flocculant polyaluminum chloride 10kg, re-inject mine water into the underground roadway through drilling, and slowly flow through the 700m-long main roadway 1 from above the baffle plate, so that the neutralization, flocculation, and pr...

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...
