Description

technical field [0001] The invention relates to the technical field of waste water treatment systems, in particular to a high-efficiency circulation treatment system for acidic mine waste water containing heavy metal ions. Background technique [0002] Mine acid wastewater is mainly formed by the oxidation of reducing sulfide minerals by air, precipitation and bacteria in the process of mining, transportation, mineral processing, waste rock discharge and tailings storage. Mine acid wastewater has a large amount of water, a low pH value, and a high concentration of soluble heavy metal ions. Heavy metals refer to metals with a specific gravity greater than 4 or 5, and there are about 45 kinds. The usual heavy metal pollution mainly refers to the environmental pollution of heavy metals with significant biological toxicity such as mercury, lead, cadmium, chromium, and arsenic, and also includes heavy metals with certain toxicity such as Zinc, copper, cobalt, nickel, tin, vanadi...
