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 comprehensive treatment method for manganese ore wastewater through a large number of experiments and research

Embodiment 1

[0019] A comprehensive treatment method for manganese ore wastewater, the method may further comprise the steps:

[0020] a. Adsorption: import the manganese ore wastewater into the sedimentation tank, add purification materials to the manganese ore wastewater, and let it stand for 2 hours;

[0021] b. Irradiation: After the standing treatment is completed, take out the supernatant of the waste water for ultraviolet irradiation treatment. The treatment time is 15 minutes, and the irradiation distance is 40cm. Then, potassium permanganate is added, and the stirring line speed is controlled to be 10m / s to stir 10min;

[0022] c. Secondary adsorption: continue to add purification materials to the supernatant after irradiation treatment, and treat for 2 hours;

[0023] d. Coagulation and discharge: Add ferric polysilicate to the supernatant after the secondary adsorption, stir for 10 minutes and let stand for 1 hour to separate and discharge.

[0024] The purification material i...

Embodiment 2

[0027] a. Adsorption: import the manganese ore wastewater into the sedimentation tank, add purification materials to the manganese ore wastewater, and let it stand for 6 hours;

Abstract

The invention discloses a comprehensive treatment method of manganese ore wastewater. The method comprises adsorption, irradiation, secondary adsorption, coagulation and emission. The comprehensive treatment method of manganese ore wastewater adopts a double adsorption method to effectively suck a large number of harmful substances in manganese ore wastewater, and matches with ultraviolet treatment to further disinfect wastewater. A self-made purification material adopted by the invention has very strong adsorption and purification effects, simple processing method and obvious effects, finally is matched with a high-efficiency flocculant to play a role of complementing each other so as to improve the efficiency.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a comprehensive treatment method for manganese ore wastewater. 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 radioac...
