Problems solved by technology

However, the unsettled coal mining subsidence area is constantly sinking, and the water accumulation area continues to expand with the coal mining activities. It is a special water environment that is constantly sinking, so a single method cannot be used. Treatment of water body environment in subsidence area by ecological engineering method

Embodiment Construction

[0023] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0024] The treatment methods for the coal mining subsidence area include:

[0025] S1: The coal mining subsidence area adopts the management mode of classification and classification, and selects the most suitable management mode for each subsidence area according to the characteristics of each type of subsidence area.

[0026] S2: Sorting out the water system for the construction of the water system, connecting the current water body to meet the requirements of water ecological cycle and purification, and pre-treating and purifying the current water system through wetland construction, increasing the activity of the water body, degrading harmful substances, and purifying Became three kinds of water quality.

Abstract

The invention relates to the field of environmental treatment, and concretely relates to a coal mining subsidence area treatment method and a water pollution control system. The problem of unsatisfactory treatment effect of existing coal mining subsidence areas is solved. The method comprises the following steps: graded and classified treatment mode of a coal mining subsidence area, water system construction for water system combing, ecological restoration, and a mode of combining with landscape nodes and utilizing indoor and outdoor science popularization modes to realize interactive and participatory science popularization, propaganda and education functions. The subsidence area is provided with a diversion canal, a sedimentation tank, a water distribution channel, a surface wetland, a subsurface wetland, a clear water pool and a water outlet. The method has the ecological environment for effectively repairing the coal mining subsidence area, brings economic, social and cultural values for the development of the city where the subsidence area is located through the comprehensive treatment of the subsidence area field and the reuse of the subsidence area, and becomes a new templetfor the treatment of domestic coal mining subsidence area.

Description

technical field [0001] The invention relates to the field of environmental treatment, in particular to a treatment method for a coal mining subsidence area and a water pollution control system. Background technique [0002] my country's coal resources are widely distributed, and there is a huge dependence on coal resources. Due to the non-renewability of coal resources and the accumulation effect of resource mining, many mining cities have experienced resource depletion, accompanied by a large number of coal mining subsidence areas with complex geological conditions and serious water and soil damage. Coal mining subsidence refers to the subsidence of the overlying strata and landmarks caused by coal mining underground. When the coal seam mining expands to a certain extent, an approximately elliptical subsidence basin that is much larger than the goaf will be formed on the surface. The original flat land is uneven, resulting in soil erosion, seasonal or perennial water accum...
