Urban and surrounding high-groundwater-level mining subsidence area landscape water body regulation and ecological purification method

Abstract

The invention relates to an urban and surrounding high-groundwater-level mining subsidence area landscape water body regulation and ecological purification method, which is applicable to the field ofecological treatment of a mining subsidence area. According to collapse pit-pond accumulated water and a water system which are formed in a high-groundwater-level mining subsidence area, a water resource cascade regulation network which uses a main collapse pit-pond as a big water body and uses a surrounding water system as a network system is constructed; a cascade regulation system with different water level height differences is constructed by utilizing the surrounding water system; the water body is subjected to graded regulation by utilizing a water body cascade regulation pool; then theregulated water body is filtered by utilizing a water body ecological filtering method; the filtered water body is subjected to ecological remediation by utilizing an ecological remediation gallery; then the water body is subjected to pollutant cleaning; the cleaned water body is subjected to eutrophication big water body treatment; finally, residual aquatic plants in the water body are removed byutilizing a wind regulation type floating algae collection purse net so as to reduce the water body into ecological water which accords with the standard. The urban and surrounding high-groundwater-level mining subsidence area landscape water body regulation and ecological purification method has simple steps and a good use effect, and can meet water body pollution treatment by utilizing the mining collapse pit-pond accumulated water and the water system.

Description

technical field [0001] The invention relates to a landscape water control and ecological purification method in a coal mining subsidence area, and is especially suitable for landscape water control and ecological purification methods in cities and surrounding high water level coal mining subsidence areas used in the field of ecological management of the coal mining subsidence area. Background technique [0002] 1. Long-term coal mining activities in high-water-level areas often lead to ground subsidence and ground water accumulation, resulting in regional water system disorder and uneven spatial distribution of water resources, resulting in failure of the original drainage system, and seriously insufficiency of the subsidence area's ability to resist natural disasters . Therefore, in the process of landscaping management in high-water level coal mining subsidence areas, the construction of a reasonable water body regulation technology system is the basis for guiding the rati...
