Problems solved by technology

[0004] However, the waste water in the waste gas mine is sometimes large in volume, and at this time more chemicals and energy are required, and more chemicals and energy are required for long-term operation, and the precipitation method needs to be built and operated when it is used, and the mine waste water is acidic. It is highly corrosive to equipment, so it can be seen that the operation and maintenance costs required to treat wastewater in abandoned mines by sedimentation are relatively high

Abstract

The invention provides a mine pit wastewater pre-treatment device, and relates to the technical field of the mine pit wastewater treatment. The mine pit wastewater pre-treatment device comprises a first treatment part and / or a second treatment part. The first treatment part comprises an intra-pit treatment unit, a first hydraulic drop aerating unit and a first precipitate treatment unit which aresuccessively connected. The intra-pit treatment unit is installed in a waste mine pit. The intra-pit treatment unit is provided with the water outlet end penetrating through the mine pit. Each of thefirst hydraulic drop aerating unit and the first precipitate treatment unit is provided with the water inlet end and the water outlet end. The second treatment part comprises an anoxic treatment unit,a second hydraulic drop aerating unit and a second precipitate treatment unit which are successively connected. The anoxic treatment unit is connected with the first precipitate treatment unit or connected with the mine pit. A technical problem in the prior art that needed operation and maintenance cost is higher by using a neutralization precipitation method to treat wastewater in the mine pit is solved. The first treatment part and / or the second treatment part of the mine pit wastewater pre-treatment device is capable of realizing the adequate treatment to the wastewater in the waste mine pit.

Description

technical field [0001] The invention relates to the technical field of mine wastewater treatment, in particular to a mine wastewater pretreatment device. Background technique [0002] During the mining process of metal mines and coal mines, a large number of mine holes will be produced. During the operation of metal mines and coal mines, the mine holes will be drained regularly, and the mine holes will not produce water gushing, but the mine holes will be abandoned after they are abandoned. , there is no one to manage the mine, the groundwater in the mine will continue to rise, and there may be water gushing in the mine; the water gushing out of the mine is generally acidic, and the iron content in the wastewater is high, and the concentration can reach Hundreds to thousands of mg / L, resulting in yellow water from mines. In addition, according to different types of mines, some mine wastewater also contains heavy metals. The acid wastewater from abandoned mines directly ente...
