Device and treatment method for deep purification treatment of mine water for production

Abstract

The invention discloses a device and a treatment method for deep purification treatment and reuse of mine water for production, and the device comprises a ground water storage tank, a high-level primary sedimentation water storage regulating tank, a reuse water tank and an underground production water supply system, the ground water storage tank is connected with the high-level primary sedimentation water storage regulating tank through a water pipe; the high-level primary sedimentation water storage regulating tank is connected with a multi-medium filter through a purification device pipeline, the multi-medium filter is connected to the underground production water supply system through a membrane biological reaction tank and the reuse water tank, and an automatic dosing device is arranged on a water delivery pipe. By additionally arranging the automatic dosing device and an automatic control system, the dosing amount is adjusted according to the change of the water inlet flow, the dosage of a medicament is accurately controlled, and the flocculation effect is exerted to the maximum extent. And the MBR technology is utilized, so that the solid-liquid separation efficiency is greatly improved. Purified mine water is disinfected in the mode that a generator is adopted to prepare sodium hypochlorite on site, the operation cost is reduced, accurate medicine adding is achieved, thedisinfection effect is improved, and the mine water returns to an underground production system again.

Description

technical field [0001] The invention relates to a mine water treatment equipment, in particular to a device and a treatment method for deeply purifying mine water for reuse in production, and belongs to the technical field of mine water treatment equipment. Background technique [0002] my country is recognized as one of the countries in the world that is severely deficient in per capita water resources. With the continuous increase of population and the rapid development of economy, the demand for water for industry, agriculture and domestic use is also increasing, resulting in the shortage of fresh water resources. It is becoming more and more serious. Since the 21st century, my country is the country with the largest coal output in the world. At the same time, the discharge and production of coal mine water are also the first in my country's industrial wastewater. Therefore, the level of mine water resource treatment should be improved and the mine water resource treatment ...

AI Technical Summary

Problems solved by technology

In order to protect the safety of underground mining production projects and prevent mine floods caused by excessive mine water pouring into the mine, mine water needs to be pumped out of the mine during the mining process. The treatment standard does not meet the production and discharge requirements, which will form a huge water resource. waste, while mine water contains pollutants that will damage local ecosystems
