Apparatus and method for processing antimony ore acidic waste water

Abstract

The invention discloses an apparatus for processing antimony ore acidic waste water, the apparatus is composed of a shallow water diversion oxidation sedimentation pool, a secondary oxidation sedimentation pool, a secondary oxidation sedimentation pool, a first microbe reduction pool, a secondary microbe reduction pool and a buffer pool; the shallow water diversion oxidation sedimentation pool is positioned at the forefront, and is connected to the secondary oxidation sedimentation pool, the secondary oxidation sedimentation pool, the first microbe reduction pool, the secondary microbe reduction pool and the buffer pool in order. According to the invention, the apparatus of the present invention is used for processing antimony ore acidic waste water, the pH value of water body is greatly increased from 2.77-2.89 to 7.65-7.95, Sb content in the water body is obviously and respectively reduced from 1656-2880mumg/L to 18.2-34.6mumg/L, subduction amount of Sb can reach to 98.2-99.2%, the water quality is greatly improved, and the value is far better than the relative Sb limit value (500mumg/L) in an industrial draining standard of our country.

AI Technical Summary

Benefits of technology

This new treatment system helps create an environmentally friendly solution by utilizing recycled material from various sources like bauxite or sintered clay mineral production processes without adding any harmful compounds that may be found on their surface. Overall, it provides technical benefits over existing methods with lower costs, ease of operation, flexibility, and sustained effectiveness compared to current technologies.

Problems solved by technology

This patented problem addressed in this patents relates to treating acidic wastes such as antiquity dumped areas due to their potential environmental concerns. Current methods involve expensive chemicals that require manual addition or electrical devices, which may result in contamination with other materials used during production. Limes also have limitations because they produce unwanted side effects on nearby environments.
