Abstract

The invention provides an acid mine drainage treatment system, and relates to the technical field of the water treatment. The acid mine drainage treatment system comprises a neutralizing treatment unit for performing a neutralization reaction on wastewater, an aerating treatment unit for aerating the wastewater, a precipitate treatment unit for performing precipitation on the wastewater, a first-level deep-treatment unit for performing first-level deep-treatment on the wastewater, a second-level deep-treatment unit for performing second-level deep-treatment on the wastewater and a water outletunit which are successively communicated. The neutralizing treatment unit is internally provided with an alkaline material. The first-level deep-treatment unit is internally filled with a first deep-treatment agent. The second-level deep-treatment unit is internally filled with a second deep-treatment agent. A water outlet end of the water outlet unit is provided with a water outlet channel. A technical problem in the prior art that required cost is higher while the wastewater in a waste mine pit is treated is solved. The acid mine drainage treatment system is capable of, through the neutralizing treatment unit, the aerating treatment unit, the precipitate treatment unit, the first-level and second-level deep-treatment units and the water outlet unit, realizing the adequate treatment to the wastewater.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an acid mine drainage treatment system. 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 the mine, the mine holes will be drained regularly, and there will be no water gushing in the mine holes. After the mine holes are abandoned, the groundwater in the mine holes will continue to rise and appear. The phenomenon of mine water gushing, mine water is generally acidic, with high iron and manganese content, and the concentration can reach hundreds to thousands of mg / L, resulting in mine water gushing yellow. In addition, depending on the type of mine, some mine wastewater also contains heavy metal. Acidic wastewater from abandoned mines enters the downstream river, which will cause serious pollution to the river and requires effective treatment. [0003] The existing...
