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,

Embodiment Construction

[0017] The present invention aims at the present situation that the current mine water treatment equipments are all concentrated on the ground, occupying a large area, and the transportation distance of water treatment and reuse is long, and develops an underground mine water treatment system. System, filtration system, antiscaling system, water supply system. Mine water is first precipitated by the sedimentation system, then filtered by the filtration system, and finally purified by the antiscalation system to obtain clean water that can be reused. The water supply system includes multiple water pumps.

[0018] Its preferred implementation is as figure 1 As shown, the system includes a sedimentation tank 3, a two-stage filtration system 7, 8, a scale inhibitor 9, multiple water pumps, a backwashing device and a control system (not shown in the figure).

[0019] The raw water of the mine water enters the sedimentation tank 3 from the underground water tank 1 through the lift p...

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. Disadva...
