Coal mine underground sewage water quality softening reuse process treatment system

Abstract

The invention provides a coal mine underground sewage water quality softening reuse process treatment system. A sewage treatment chamber is arranged in a mining region; a water sand separator, an inner ring sewage cabin and an outer ring sewage cabin are arranged in the sewage treatment chamber; mine inflow is discharged to the water sand separator; after being separated by the water sand separator, the water is conveyed to the inner ring sewage cabin; mine water passes through the inner ring sewage cabin and is then conveyed to the outer ring sewage cabin; a water treatment region comprises water treatment water distribution cabins, a water treatment water collection cabin, a chemical reactor, a primary coagulation reaction pool, a secondary coagulation reaction pool, a magnetic separation machine, a water outlet water cabin and a water treatment control device; the quantity of the water treatment water distribution cabins is matched with the mining regions; the mine water of each mining region is gathered and is collected to the water treatment region in a concentrated way for unified treatment. The distributed arrangement of treatment equipment is avoided; the centralized management on sewage treatment cannot be realized; the investment cost is high; the operation cost is high.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to a treatment system for the softening and reuse process of underground sewage in coal mines. Background technique [0002] Coal mines are energy sources with a large demand for economic construction and social development. In the process of coal mining, sewage will be generated under the mine. If the sewage is not treated well, it will easily affect the geological environment and ecological system of the mining area, and the shallow groundwater resources will be depleted. And water pollution, etc., but also lead to serious water shortage in mining areas. [0003] In order to avoid the impact of coal mine sewage on the geological environment of the mining area and the ecological system around the mining area, and to meet the normal production needs, it is necessary to recycle the mine water, which not only protects the safety of mining production and water supply in the mining area, but...

AI Technical Summary

Problems solved by technology

This brings great preparations in advance for coal mining preparations, and the scattered arrangement of treatment equipment makes it impossible to achieve centralized management of sewage treatment, resulting in high investment costs and high operating costs.

[0005] Moreover, at present, only mine sewage is tested in each mining area, or a fixed mode of mine water treatment formula is adopted in each mining area to deal with different time periods and different locations of mine treatment, and then the water quality after treatment is tested, if If it does not meet the standard, it will be treated again to make the mine water meet the specification requirements

This leads to a long cycle of mine sewage treatment, and it is difficult to meet the specification requirements in one treatment

Secondary treatment wastes water treatment resources and cannot form an effective mine sewage treatment method
