A method for treating water in coal mine underground reservoir

Abstract

The invention discloses a treatment method of a water body in a coal mine underground reservoir. The method comprises the following steps: 1 dividing a water body into a suspended solid over-standard water body, a heavy metal over-standard water body and an organic matter over-standard water body according to the water conditions of water bodies entering the underground reservoir from different underground mine water sources; 2 correspondingly dividing the underground reservoir into a suspended solid pollution treatment reservoir for removing suspended solids, a heavy metal pollution treatment reservoir for removing heavy metals and a reagent treatment reservoir for removing organic matters and inorganic matters through reagents; and 3 introducing the suspended solid over-standard water body into the suspended solid pollution treatment reservoir, processing the suspended solid over-standard water body into a qualified water body through direct filtration, introducing the heavy metal over-standard water body into the heavy metal pollution treatment reservoir, processing the heavy metal over-standard water body into a qualified water body through a modular water treatment method, introducing the organic matter over-standard water body into the reagent treatment reservoir, and processing the organic matter over-standard water body into the qualified water by adding a reagent.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of mining engineering and water conservancy engineering, in particular to a treatment method for water bodies in coal mine underground reservoirs. Background technique [0002] my country is a water-short country, and the shortage of water resources poses a serious threat to the development of the national economy and the improvement of people's lives. Mine water is unavoidable in the process of coal mining. As a precious water resource, the mine water discharged by key state-owned coal mines alone is as high as 2.2 billion tons every year. On average, every ton of coal mined needs to discharge 2 tons of wastewater. On the one hand, the discharge of mine water not only wastes a lot of precious water resources, but also easily constitutes serious environmental pollution to the surrounding environment. On the other hand, there are abundant coal resources in the western region of m...

Problems solved by technology

However, the pollution sources of coal mine water are different. In the process of purifying mine water by using coal mine underground reservoirs, different polluted water bodies cross each other, which is easy to cause mutual influence and affect the mine water purification effect.
