Abstract

An experimental facility for collecting leachate during mining wasteland remediation relates to ecological remediation experiment facilities. A percolation device 1 adopts the structure that a percolation plate 2 on the upper surface of the percolation device 1 is connected with an impermeable plate 4 on the lower surface of the percolation device 1 through support pillars 3; a baffler 16 is connected to the front end of the percolation device 1; a leachate outlet 5 is formed in the baffler 16; percolation guiding holes 15 are uniformly distributed on the percolation plate 2; the leachate outlet 5 is connected with the end of a flow guide device 7, of which the caliber is thinner, through a hose 6; a porous filter screen 8 is arranged in the inner cavity at the end, with a thicker caliber, of the flow guide device 7; the end of the flow guide device 7, of which the caliber is thicker, is connected with one lateral port of a filtering device through a plastic hose; a top cap is mounted at the top of the filtering device; a detachable filter screen is placed at the lower part of the inner cavity of the filtering device; and a spherical valve is mounted at the lower end of the filtering device. Through the adoption of the experimental facility, leachate of natural rainfall or manually simulated rainfall can be collected in a controllable manner in an in-situ experiment of mining wasteland ecological remediation, so as to solve the problem that laboratory simulation study cannot reflect field environmental conditions completely.

Description

technical field [0001] The invention relates to an experimental device for ecological restoration, in particular to an experimental device for leachate collection in mine abandoned land restoration. Background technique [0002] In today's rapid economic development, large-scale mining of mines occupies and destroys a large amount of land resources, and for a long time after mining and mining, ore dust, mining wastewater discharge, surface runoff, landslides, subsidence and other processes continue to pollute and destroy Surroundings. Therefore, the ecological restoration of mine abandoned land is an indispensable task in the sustainable development of the mining industry and even the national economy. However, due to the extremely harsh site conditions of abandoned mines, there are many factors that limit the growth of plants, and artificial assistance measures are needed, such as applying repair substrates or modifiers to improve the site conditions of abandoned sites, a...
