Problems solved by technology

[0007] The object of the present invention is: existing filtration membrane comprises ultrafiltration membrane, microporous filtration membrane, nanofiltration membrane, microfiltration membrane, hollow fiber ultrafiltration membrane, Purcell filtration membrane etc., and the filtration effect of these membranes is all better, However, the production cost is high, and the effect on arsenic removal is not obvious. Therefore, in view of the above-mentioned problems, the present invention provides an arsenic removal membrane for treating arsenic-containing wastewater in mines, which is specially designed to treat arsenic in arsenic-containing wastewater in mines, and improves the arsenic removal rate. Filtration efficiency

Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] In the prior art, methods such as adsorption method, ion exchange method, membrane separation, biological method, chemical precipitation method and coagulation sedimentation method are usually used to treat arsenic-containing wastewater. In these methods, membrane separation uses membrane as the separation medium. A method of separating, fractionating, purifying and concentrating a two-component or multi-component fluid with external energy or chemical potential difference as the driving fo...

Abstract

The invention discloses an arsenic removal film for treating arsenic-containing wastewater in a mine. The arsenic removal film is prepared from the following raw materials: bamboo pulp fiber, glass fiber and eggshell powder, and the bamboo pulp fiber is mixed with the glass fiber and then wet process paper technology is used for papermaking the arsenic removal film, and the bamboo pulp fiber and the glass fiber are evenly spread out in a crisscross pattern. The bamboo pulp fiber, the glass fiber and the egg shell powder of the arsenic removal film has multiple functions, and the film made by the three has a very good separation and purification effect on arsenic in the arsenic-containing wastewater in the mine, and greatly improves the efficiency of arsenic removal. .

Description

technical field [0001] The invention relates to the field of mine wastewater treatment, in particular to an arsenic removal membrane for treating arsenic-containing wastewater in mines. Background technique [0002] Many production processes in mine production require water, among which mining and beneficiation use the most water. The mining and beneficiation process will cause serious water pollution and form mine wastewater. Mine water pollution refers to the phenomenon that mining industrial wastewater and domestic sewage containing various pollutants and toxic substances change its normal composition after being discharged into the water body, exceeding the self-purification ability of the water, thereby deteriorating the water body and destroying the original use of the water body. The types of mine water pollutants include acid wastewater pollution, heavy metal pollution and nutrient enrichment pollution. The direct discharge of these pollutants will cause irreversible...
