Method for landscape water body regulation and ecological purification of urban and peripheral high-water-table coal mining subsidence areas
The invention relates to a method for landscape water body regulation and ecological purification of urban and peripheral high-water-table coal mining subsidence areas, which is suitable for the field of ecological treatment of the subsidence area in coal mining areas. The method comprises the following steps of: constructing a water resource cascade regulation and control network by taking a main collapse pit as a large water body and taking a surrounding water system as a network system according to collapse pit ponds and water systems formed in a high diving level coal mining subsidence area; constructing a cascade regulation and control system with different water level heights by using the surrounding water system; performing hierarchical regulation and control on the water body by using a water body cascade regulation and control pool; filtering the regulated water body by using a water body ecological filtering method; performing ecological restoration on the filtered water body by using an ecological restoration corridor; cleaning pollutants in the water body; and performing eutrophic large water body treatment on the cleaned water body. The method has the advantages of being simple in steps and good in use effect, and can meet the water body pollution control by utilizing the water accumulation and the water system of the coal mining collapse pit. -3/6 Circulation unit Land plant Floating plants + emergent Submerged plant Submerged plant Land plant Floating plants + emergent aquatic plants ecological ecological floating aquatic plants Submerged plant Ecological filtering floating island island Ecological filtering ecological floating system for water body ytem forwater body island Underground drainage pipe in same section (used duringI cleaning of dry pool) Direction of water flow Figure 3
