A tailings pool heavy metal pollution and geological disaster prevention and control system

Abstract

The invention discloses a tailings pond heavy metal pollution and geological disaster prevention and control system. A fixed frame and a water-permeable layer are sequentially arranged along the seepage flow direction of the tailings pond. In the frame, a chute is provided outside the reverse osmosis reaction box, and the chute is slidably matched with the vertical slide rail. The inside of the reverse osmosis reaction box is provided with a vertical partition, which divides the inside of the reverse osmosis reaction box into left and right sides. Two areas, the right area is close to the tailings pond, the left area is far away from the tailings pond, the right area is equipped with a reverse osmosis layer, the left area is equipped with a reaction layer, the right area is equipped with water inlet holes, and the left area is equipped with water outlet holes. The partition is provided with a water hole. The fixed frame of the present invention combines the reverse osmosis layer and the reaction layer of the reverse osmosis reaction tank and cooperates with the water permeable layer to form an integrated structure of blocking-reaction-permeation, which can effectively intercept heavy metal pollutants in the seepage of tailings, and has high stability and can effectively block Mud, sand, soil and rocks are used to prevent geological disasters such as water and soil erosion.

Description

technical field [0001] The invention belongs to the technical field of tailings treatment, and in particular relates to a tailings reservoir heavy metal pollution and geological disaster prevention and control system. Background technique [0002] The ore undergoes a series of sorting operations to obtain concentrates, and the remaining components are discharged in the form of slurry to form tailings. Tailings dams are mainly used to store tailings or other industrial wastes discharged from ore sorting in metal and non-metal mines, and play a great role in the protection and management of the mine environment. [0003] The core issues of tailings dam design and construction are storage capacity and safety issues. The problem of storage capacity involves economic issues such as the service life of tailings storage and the ratio of input to output. The safety issue involves issues such as people's life and property and ecological environment protection. [0004] Tailings da...

AI Technical Summary

Problems solved by technology

Both of them did not take into account the service life of the reaction layer and the problem of material replacement in the later period

However, because there is no load-bearing structure, the strength and rigidity of the wall are insufficient, and it is impossible to maintain the stability of the yard
