Tailing pond ecological treatment method

Abstract

The invention discloses a tailing pond ecological treatment method. The method comprises the steps that (1), slope surface topography finishing and danger removing are conducted; (2), net hanging andanchoring rod construction treatment are conducted on the slope surface of the edge slope; (3), a water pump and an irrigation system are arranged, and a percolating water at the deep layer of the tailing pond is extracted to be used for the irrigation system; (4), soil similarity culture medium bottom layer spraying sowing is conducted; (5), soil similarity culture medium surface layer spraying sowing is conducted; (6), edge slope curing management is conducted, wherein the edge slope curing management comprises the steps of non-woven fabric coating on the surface layer of the soil similarityculture medium, non-woven fabric reinforcing, watering, fertilizer applying, plant diseases and insect pests preventing and treating, replanting and later-period monitoring. The invention provides the edge slope plant tailing pond ecological treatment method which has a reasonable and stable soil structure and can rapidly form ecological system stability.

Description

technical field [0001] The invention relates to an ecological treatment method for a tailing pond, belonging to the technical field of vegetation. Background technique [0002] With the rapid development of my country's mining industry, a large amount of tailings waste has been produced. The treatment and disposal of these waste residues are generally stored in the form of tailings ponds, which not only occupy a large amount of land, but also pollute soil, groundwater and surface water through acidification and rainfall leaching. Moreover, due to the loose nature of the tailings sand, the slope is prone to water and soil loss when it encounters precipitation. In areas with severe wind erosion, it is easy to generate dust from the tailings sand. The existing measures are usually to plant plants with a certain thickness of planting soil to restore the ecology and improve the governance effect. Poor, high cost, long-term maintenance is required. Contents of the invention ...
