Problems solved by technology

During the mining process, a large amount of waste water and rocks are discharged from the underground, polluting rivers, occupying a large amount of farmland, forests, and pastures, and destroying the ecological balance. It can be seen that if manganese ore wastewater is not properly treated, it will cause serious environmental pollution. The inventor provided a method for adsorbing manganese-containing wastewater through a large number of experiments and researches

Abstract

The invention discloses a method for adsorption treatment on wastewater containing magnesium. The method includes the steps of adsorption, irradiation, secondary adsorption and coagulation discharging. The primary adsorption and the secondary adsorption are adopted for effectively removing a lot of harmful substances in the wastewater containing magnesium in an adsorbing mode, and the wastewater is further sterilized in cooperation with treatment of ultraviolet rays. A self-made carbonized material is adopted and has quite high adsorbing and purifying effects; the method for treatment is simple, and obvious effects are achieved; finally, in cooperation with efficient flocculants, the effects of mutual complementation and efficiency improvement are achieved with the carbonized material.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a method for adsorbing wastewater containing manganese. Background technique [0002] The mining of manganese ore will produce a large amount of manganese ore wastewater. During the long-term discharge of manganese ore wastewater, the water flow capacity of the drainage pipe will be reduced, and a large amount of sediment will be generated in the pipeline. In severe cases, the pipeline will be broken. When it enters our normal drinking water, it will also cause chronic poisoning and endanger human health. However, my country's manganese ore resources are relatively scarce, and there are few rich ores. my country's manganese-containing waste and manganese-containing waste water pollution is relatively serious, manganese ore mine water pollution can be divided into mineral pollution, organic pollution and bacterial pollution. In some mines, there are also radioactive ma...
