A kind of mine wastewater intelligent treatment equipment and method

Abstract

The invention relates to a mine waste water intelligent treatment device and method. The device comprises a filter tank, a heavy metal settling tank, an organic matter removing tank, a sterilizing tank, a PH regulating tank and a water storage tank, wherein a first branching tank, a second branching tank and a third branching tank which are connected with a water source are respectively arranged in the filter tank; an outlet of the first branching tank, an outlet of the second branching tank and an outlet of the third branching tank are connected with the heavy metal settling tank; an alkali liquor adding tank is arranged above the heavy metal settling tank; an alkali liquor outlet is formed in the bottom surface of the alkali liquor adding tank; an outlet of the heavy metal settling tank is connected with the organic matter removing tank; an activated carbon adsorption layer is arranged in the organic matter removing tank; an outlet of the organic matter removing tank is connected with the sterilizing tank; an outlet of the sterilizing tank is connected with the PH regulating tank; an acid liquor adding tank is arranged above the PH regulating tank; and an outlet of the PH regulating tank is connected with a water storage tank. The method is compact in step, mine waste water can be treated, the treated mine waste water can be drained directly, and can also be reused, the treatment efficiency is high, meanwhile, the treatment effect is good, and harm to the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of mine wastewater intelligent treatment, and in particular relates to a mine wastewater intelligent treatment equipment and method. Background technique [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 pre...

[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
