Problems solved by technology

[0002] Mine wastewater mainly includes mining mine water and mineral processing wastewater, of which mineral processing wastewater accounts for the majority. Mine wastewater has complex water quality and various components, including various heavy metals, organic chemicals and other pollutants. If it is discharged outside, it will cause serious damage to the surrounding ecological environment. If it is returned to the production process, as the harmful substances in the wastewater will continue to accumulate, it will also have an adverse impact on the production process and equipment. Therefore, it is necessary to choose an appropriate treatment method to treat these wastewater
[0003] At present, the commonly used treatment methods include chemical precipitation method, adsorption method, microbial method, artificial wetland method, etc. Although these treatment methods have certain advantages, they are generally limited by factors such as mine production conditions, environmental conditions or treatment requirements. For example, the treatment effect of heavy metals by chemical precipitation is relatively good, but the treatment effect of organic substances is poor; the adsorption method can effectively treat heavy metal wastewater, but when the adsorbent is regenerated, the pollutants will be regenerated; the cost of microbial treatment is relatively low, but Reaction conditions are relatively harsh, and it is difficult to be popularized and applied; the wetland method occupies a large area, and the treatment cycle is long, and it is difficult to meet the treatment requirements
