Mine dewatering water purification system and construction method thereof

Abstract

The invention discloses a mine dewatering water purification system and a construction method thereof. The mine dewatering water purification system comprises a storage functional area, a purificationfunctional area, a landscape functional area and a plant diversity functional area which are sequentially arranged from top to bottom on the original riverway of a slope, wherein gabion retaining walls are arranged among the areas, and the gabion retaining walls are step-shaped. According to the method, the original riverway is transformed; water storing and filtering functions are added; througha flow guiding and water catchment mode, dewatering water is collected and introduced into the transformed riverway, and large sundries such as branches and rocks of the dewatering water are filteredthrough the stilling gabions; plants are planted in a water storage area, so water quality is transformed, the dewatering water flowing to the lower stream becomes purified water, and a downstream river is prevented from being polluted; moreover, management and protection are convenient, attractiveness and elegance are achieved, and water resources are saved.

Description

technical field [0001] The invention relates to the field of mine drainage, in particular to a mine drainage water purification system and a construction method thereof. Background technique [0002] Drainage water is the sewage that gushes out from the coal seam during the coal mining process. There are many sources of sewage, such as the surface seepage water produced during mine mining and the water in the groundwater layer, which is covered by sand and mud particles, dust, dissolved salt, acid and alkali, Formed by coal particles, grease and other pollution. [0003] At present, the mining area drainage project mainly installs a hard retaining wall in the channel of the subsidence area to discharge the drained water. However, the hard retaining wall is broken due to the surface subsidence of the mining area or the rainwater flows randomly during the heavy rain, which wastes water resources and pollutes the downstream. water bodies, affecting the water quality of rivers....
