Problems solved by technology

[0002] Areas such as stopes, storage yards, smelters, tailings ponds and slag yards within the scope of metal mine mining areas will generate a large amount of wastewater. The wastewater discharged from the above areas contains a large amount of heavy metal elements. Wastewater will flow out of the mining area along the surface water path, which will pose a serious threat to the natural environment and the health of residents downstream of the mining area; at present, there is no effective prevention and treatment method for the heavy metal ions dissolved in the surface water of the mining area, and it is urgent to wait for a solution

Abstract

The invention relates to a prevention and treatment method for heavy metal pollution of mining area surface water, which comprises the following steps: (1) investigating the pollution condition of the mining area surface water, and selecting an engineering treatment position; (2) constructing a purification system; (3) detecting and determining a treatment effect and a material adsorption saturation degree; and (4) replacing the purifying and repairing material. The method can effectively remove the heavy metal ions dissolved in the surface water in the mining area so as to avoid damage to the downstream natural environment and resident health, and is low in manufacturing cost, good in effect and simple and convenient to operate.

Description

Technical field [0001] The present invention relates to a method of prevention and treatment treatment of moisture metal contamination in a mine surface water. Background technique [0002] Involuble, yards, smelters, tailings and slag fields in the metal mine mining area, have a large amount of wastewater, and the wastewater emitted in the above area contains a large number of heavy metal elements containing a large amount of heavy metal contamination elements. Wastewater will flow out of the mine area along the ground, which will bring serious threats to the natural environment and residential health downstream of the mining area; at present, the heavy metal ions that have been dissolved in the mine floor water, there is no effective prevention and treatment method, and it is urgent to wait to solve . Inventive content [0003] The technical problem to be solved by the present invention is to provide a weight metal ion dissolved in the mine surface water to avoid damage to the...
