Treatment method of mine wastewater

The invention relates to a treatment method of mine wastewater. The method comprises the following steps: (1) mixing acidic mine wastewater and flotation wastewater in a volume ratio of (1:1)-(2:1), stirring to mix the wastewater uniformly, adding H2O2, continuously stirring to react, and then standing for layering; and (2) taking the layered supernatant, adding lime milk to adjust the pH value of the wastewater to 6.0-8.0, adding a polyacrylamide (PAM) solution after the generation of precipitates, stirring, and standing for layering to obtain a supernatant which can be discharged according to the standard. By utilizing the method provided by the invention, the defects of the prior art can be overcome, the quality characteristics of raw water is fully utilized, and waste is treated with waste; and the pollutants in the water can be removed efficiently, the cost is low, and the method has a good application prospect.
