Problems solved by technology

[0002] At present, in the mineral processing process, a large amount of wastewater must be produced, resulting in a large amount of mine wastewater being discharged into the water body basin, making the mine mineral processing wastewater pollute the environment
Especially for the beneficiation process of lead-zinc ore, it contains a large amount of metal elements, such as Zn, Cd, Pb, As, etc. After these metal elements flow into the environment, it is very easy to cause environmental pollution, and due to the nature of the original ore, lead to , the mineral water contains a large amount of mud, which makes the concentration of the pulp in the mineral processing water extremely unstable, resulting in the extremely unstable composition of the mineral processing wastewater, resulting in the loss of a large number of heavy metal elements, resulting in a great degree of environmental pollution

Abstract

The invention relates to the technical field of wastewater treatment, in particular to a lead zinc ore beneficiation wastewater treatment method and a treatment device for the lead zinc ore beneficiation wastewater. By means of setting the structure of the device, the device can realize accurate coupling of chemical precipitation and membrane treatment methods, so that lead zinc ore beneficiation wastewater can be treated by coupling of chemical precipitation and membrane treatment; meanwhile, the shortcoming that a membrane treatment unit is damaged due to improper acidity in a chemical precipitation process is overcome, and the cost of lead zinc ore beneficiation wastewater treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a method for treating lead-zinc mine beneficiation wastewater and a treatment device thereof. Background technique [0002] At present, in the mineral processing process, a large amount of wastewater must be generated, resulting in a large amount of mine wastewater being discharged into the water body basin, causing the mine mineral processing wastewater to pollute the environment. Especially for the beneficiation process of lead-zinc ore, it contains a large amount of metal elements, such as Zn, Cd, Pb, As, etc. After these metal elements flow into the environment, it is very easy to cause environmental pollution, and due to the nature of the original ore, lead to , The large amount of mud in the mineral water makes the pulp concentration in the mineral processing water extremely unstable, resulting in the extremely unstable composition of the mineral processing was...
