Beneficiation wastewater recycling system and method based on membrane chemical reactor

Abstract

The invention discloses a beneficiation wastewater recycling system and method based on a membrane chemical reactor. The beneficiation wastewater recycling system comprises a pretreatment bin, a stamping mechanism, an air flotation machine, a sealing mechanism, a separation bin, a stirring mechanism, a security filter, and an ultra-filtration membrane group ultra-filtration membrane. The stamping mechanism is installed in the pretreatment bin, by utilizing the reciprocating down-pressing movement, waste water in the waste residues is extruded before the waste residues are treated, and thus a small amount of waste water can be conveniently extracted and treated; the sealing mechanism is mounted in a collection bin, after the scum scraping is finished, a hand wheel is rotated to enable a winding wheel to lift an inserting plate through a steel rope, then the waste water in the scum can flow back into a bin of the air floatation machine, and the system is convenient, rapid and high in efficiency; and the stirring mechanism is arranged in the separation bin, after metal particles in waste water are filtered out through the filter membrane, the driving motor drives a gear in the stirring mechanism to conduct transmission, then a supporting rod at the bottom drives a sliding frame at the bottom to do linear reciprocating motion, the metal particles are stirred to a magnetic plate on the right side to be adsorbed, the effect is good, and the efficiency is high.

Description

Technical field[0001]The present invention relates to the related art of distributing wastewater reuse, in particular, a mineral chemical reactor based distribution wastewater reuse system and method.Background technique[0002]The mineral waste water includes the distribution process drainage, tailings, and the mineral drainage, the distribution process is generally delivered to the tailings in the tail slurry, collectively referred to as tail water; therefore, the mineral water treatment, The distribution waste water has a large amount of water, the suspension content is high, and the concentration is low, and the concentration is low, and the mineral water consumption of ore is 5 ~ 10 tons. In 1973, China's distribution wastewater discharge reached 1 billion cubic meters. The main harmful substances in the distribution wastewater are heavy metal ions and ore agents, heavy metal ions have copper, zinc, lead, nickel, iron, barium, cadmium, etc., and arsenic, and rare elements, based ...

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
