Mine water down-hole treatment system

Abstract

The invention discloses an underground processing system of mine water, which is arranged underground and comprises a deposition system, a filtering system, an anti-scale system, a water supply system and a backwashing device; wherein, the reusable clear water is obtained from the mine water firstly through the sedimentation of the deposition system, then the filtration of the filtering system and the anti-scale of the anti-scale system; the deposition system comprises a flow tank; the filtering system comprises a primary filter and a fine filter; the anti-scale device of the anti-scale system is an electron type or a permanent magnet type; the backwashing device is used to wash the filtering system. The flow tank comprises an even flow area and a skew plate area, and the mine water is deposited from the even flow area to the skew plate area. The fine filter with double filters is provided with a nutshell filter and a ceramisite filter. The invention is more particularly suitable for water treatment of coal mine and the underground treatment to coal mine with high suspended solids and mine water containing iron and manganese. The invention has the advantages of simple structure, low cost, high efficiency and safety.

Description

technical field [0001] The invention relates to a water treatment technology, in particular to an underground mine water treatment system. Background technique [0002] According to the characteristics of mine water pollutants, it is generally divided into: conventional mine water, high salinity mine water, acid mine water and special polluted mine water. High suspended solids and iron-manganese-containing mine water in coal mines are mine waters with special pollutants. Groundwater containing iron and manganese is widely distributed in my country, so high-suspended solids and iron-manganese-containing mine water are also widely distributed. The current mine water treatment systems are all built on the ground. The treatment equipment for mine water with high suspended solids and iron and manganese content still uses traditional sedimentation and manganese sand filters, so there are backward processes, low efficiency, and unsatisfactory water quality after treatment.

AI Technical Summary

Problems solved by technology

The current mine water treatment systems are all built on the ground. The treatment equipment for mine water with high suspended solids and iron and manganese content still uses traditional sedimentation and manganese sand filters, so there are backward processes, low efficiency, and unsatisfactory water quality after treatment. Disadvantages such as large footprint

The bigger problem is the long distance of water treatment and reuse, the large investment in power equipment and pipelines, not only high maintenance costs, but also high energy consumption, especially with the expansion of coal production scale, the amount of mine water exceeding 10 million tons per year is increasing , most of which are imported and expensive fully-mechanized mining equipment. The emulsion ratio is generally the mine water after simple precipitation in the underground water tank. There are suspended solids, iron and manganese and other pollutants, which are easy to cause corrosion of equipment and expensive maintenance costs. and affect production safety
