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.
