Underground mine water treatment system and method

Abstract

The invention relates to the field of drainage and purification treatment in coal mines, and in particular relates to an underground mine water treatment system. The underground mine water treatment system comprises a preliminary sedimentation tank, a mixed reaction tank, a super magnetic separator and a filter which are connected in sequence, wherein the super magnetic separator is connected with an underground sump; the underground sump is connected with the filter through a drainage pump; the filter is connected with a clean water tank; the preliminary sedimentation tank, the mixed reaction tank, the super magnetic separator, the underground sump and the drainage pump are arranged in an underground water treatment chamber; the filter and the clean water tank are arranged on the ground. According to the mine water treatment system, based on the characteristics of short solid-liquid separation time, high efficiency, small equipment and the like of the super magnetic separation equipment, the mine water treatment system is constructed in an underground roadway; compared with the conventional mine water treatment station, the underground mine water treatment system has the advantages that the system is not influenced by seasonal temperature changes, the quality of the treated water is stable, pump lifting is not required, a little amount of chemicals is consumed, the operation cost is saved, and the system is constructed underground to save the floor area.

Description

technical field [0001] The invention relates to the technical field of coal mine drainage purification treatment, in particular to an underground mine water treatment system and treatment method. Background technique [0002] my country's mine water purification technology began in the late 1970s and has a history of more than 30 years. According to the characteristics of large suspended solids (coal slime) and total dissolved solids in mine water, physical methods are usually used for treatment; the purification treatment technologies that have been put into use mainly include sedimentation, coagulation sedimentation, coagulation sedimentation filtration, and flocculation reaction sedimentation etc. These technologies mainly use the principle of gravity sedimentation to separate the suspended solids in the water body. The main disadvantages are large area, long hydraulic retention time, high water content of bottom sludge (coal slime), and great requirements for site and po...

AI Technical Summary

Problems solved by technology

However, conventional coagulation-sedimentation, flocculation-reaction-sedimentation and other processes have not overcome the problem of occupying a large area, resulting in long water treatment chambers and high mine construction costs; the emergence of supermagnetic separation and purification of water technology has effectively solved the above problems. Underground mine water treatment has been more and more widely used
