Abstract

The invention relates to the technical field of mine water treatment, in particular to a high-suspended-matter mine water underground short-process direct filtration treatment device and method. Comprising an adjusting tank suitable for storing mine water; the self-cleaning filter is communicated with the adjusting tank and is suitable for primarily filtering the mine water; the ultrafiltration device is communicated with the self-cleaning filter and is suitable for carrying out secondary filtration on the mine water, and a concentrated solution outlet of the ultrafiltration device is communicated with the adjusting tank so that a concentrated solution can flow back into the adjusting tank through a pump. The device is simple in filtering process, small in occupied area and low in capital construction cost; dosing is not needed, and the treatment cost is low; the method is particularly suitable for underground treatment; the water consumption of the self-flushing filter is low, and the concentrated solution in the ultrafiltration section flows back to the regulating tank for circular treatment, so that the water consumption is reduced, and the cost is further reduced; through two times of filtration, the treatment effect is good; the system can be used as a preprocessing module, can be combined with a reverse osmosis unit and the like, can also be independently applied, is not limited by use scenes, and is wider in application range.

Description

technical field [0001] The invention relates to the technical field of mine water treatment, in particular to a short-process underground direct filtration treatment device and method for mine water with high suspended matter. Background technique [0002] Mine water is produced by mining coal, and about 2.1 cubic meters of mine water is discharged for every ton of coal mined. Mine water is affected by mining and brought into coal and rock powder, containing suspended solids and bacteria, etc., and must be treated before it can be reused and utilized as a resource. The mining depth of most coal mines in my country is between tens of meters and hundreds of meters. If the mine water is pressurized to the ground for treatment, there will be excessive power consumption, fragile pump casing of the booster pump, and excessive pressure of the water supply pipeline. , The problem of difficulty in decompression of sewer pipes. Therefore, downhole processing and on-site reuse are i...
