A system and method for reusing mineral processing wastewater based on membrane chemical reactor

Abstract

The invention discloses a system and method for reusing mineral processing wastewater based on a membrane chemical reactor, comprising a pretreatment bin, a punching mechanism, an air flotation machine, a sealing mechanism, a separation bin, a toggle mechanism, a security filter and an ultrafiltration membrane group Ultrafiltration membrane, install the punching mechanism in the pretreatment bin, and use the reciprocating downward pressure motion to extrude the waste water in the waste residue before processing the waste residue, so as to facilitate the extraction and treatment of a small amount of waste water; After the slag is over, turn the handwheel to make the rewinding wheel lift the insert plate with the steel rope, and then the waste water in the scum can flow back to the air flotation machine compartment, which is convenient, fast and efficient; In the separation chamber, after the filter membrane filters out the metal particles in the waste water, the drive motor drives the gear transmission in the toggle mechanism, and then the support rod at the bottom drives the sliding frame at the bottom to make a linear reciprocating motion to move the metal particles to the Adsorption on the magnetic plate on the right has good effect and high efficiency.

Description

technical field [0001] The invention relates to the related field of mineral processing wastewater reuse, in particular to a system and method for mineral processing wastewater reuse based on a membrane chemical reactor. Background technique [0002] The beneficiation wastewater includes beneficiation process drainage, tailings pond overflow water and mine drainage. The beneficiation process drainage is generally transported to the tailings pond together with the tailings slurry, which is collectively referred to as tailings water; therefore, the beneficiation wastewater treatment is also called tailings water treatment. The mineral processing wastewater has the characteristics of large water volume, high suspended matter content, many types of harmful substances and low concentration. The mineral processing water consumption per ton of ore is 5 to 10 tons. The main harmful substances in beneficiation wastewater are heavy metal ions and beneficiation agents. Heavy metal ions...

AI Technical Summary

Problems solved by technology

[0003] In the reuse of mineral processing wastewater, in the process of separation and air flotation, the separated solids are retained by the remaining wastewater, resulting in a small amount of wastewater not being treated, which is likely to cause environmental pollution, and when separating solid metal particles, the filter membrane load is relatively heavy It needs to be replaced from time to time, and the follow-up collection and cleaning work on the surface of the filter membrane is also more complicated
