Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a mine wastewater treatment device. Background Art

[0002] Mine wastewater refers to wastewater containing various solid particles, chemicals and heavy metals generated during mining, mineral processing and smelting. The main sources of mine wastewater include mine drainage, mineral processing plant wastewater, smelter wastewater, etc. These wastewaters usually contain high concentrations of suspended solids, heavy metal ions and organic matter, causing serious pollution and damage to the environment and ecosystem.

[0003] Mine wastewater treatment equipment is a device or system used to treat mine wastewater to meet environmental emission standards or for recycling, so as to remove pollutants such as solid particles, heavy metal ions, and organic matter in the wastewater, thereby purifying the wastewater and protecting the environment and ecosystem.

[0004] China's public patent number: CN211170210U announced "A mining wastewater treatment device", including a mixing box, a base is provided at the lower end of the mixing box, a motor is fixedly installed inside the base, a stirring rod is fixedly connected to the upper end of the motor, and the stirring rod is located in the mixing box, a drainage pipe is fixedly connected to the lower part of the outer surface of the mixing box, a support frame is provided at the upper edge of the mixing box, a sedimentation box is provided in the middle of the upper end of the mixing box, a control valve is fixedly installed at the lower part of the sedimentation box, and a filter is provided at the lower part of the inner wall of the sedimentation box. The mining wastewater treatment device described in the utility model can effectively prevent impurities such as particulate matter in the wastewater from entering the mixing box by providing a filter in the sedimentation box, so as to avoid particulate matter affecting the purification effect. The stirring rod driven by the motor for stirring can promote the dissolution of the purifier, improve the processing speed, and realize rapid purification of the wastewater.

[0005] When the existing technology is in use, although it can effectively prevent impurities such as particulate matter in the wastewater from entering the mixing box, thus preventing the particulate matter from affecting the purification effect, the existing device can only filter the particulate matter during use and cannot discharge the particulate matter. As the use time increases, the particulate matter accumulates on the filter net and is easy to clog the filter net, resulting in a deterioration in the filtering effect of the filter net. At the same time, the flocculant is easily condensed into agglomerates due to the influence of water vapor in the air. The flocculant needs to be treated during use to prevent the flocculant from agglomerating and affecting the use effect. The existing device only stirs the mixed solution of sewage and flocculant and is unable to crush the agglomerated flocculant, which has a certain impact on the subsequent sewage treatment effect.

The flocculant needs to be processed during use to avoid the agglomeration of the flocculant affecting the use effect. The existing device only stirs the mixed solution of sewage and flocculant and cannot crush the agglomerated flocculant, which has a certain influence on the subsequent sewage treatment effect.
