Deep purification system for acid mine water

Abstract

The invention discloses a deep purification system for acid mine water. The system comprises a shunt regulation subsystem, a constructed wetland treatment subsystem, a neutralization method treatmentsubsystem and a deep purification subsystem, wherein the shunting regulation subsystem can shunt mine water to the constructed wetland treatment subsystem and the neutralization method treatment subsystem according to water quality conditions and can homogenize and equalize the mine water, and the constructed wetland treatment subsystem and the neutralization method treatment subsystem are both connected with the deep purification subsystem. The system effectively solves the problem that the purification effect is not ideal due to large change of the water quality of mine water, solves the problem that the change of the water quality and the water quantity of the mine water is large, purifies the mine water to different degrees, avoids environmental pollution, and meanwhile greatly solvesthe problem that a mining area is seriously lack of water.

Description

technical field [0001] The invention belongs to the field of mine water purification, in particular to an acid mine water deep purification system. Background technique [0002] Acidic mine water mainly refers to mine water with PH<6. Due to the high content of SO42-, Fe2+, Fe3+, Mn2+ plasma in acidic mine water, when there is hydraulic connection between aquifers, it will cause serious pollution to the groundwater of other aquifers. , when the acidic mine water is directly discharged without treatment and enters the surface water body, the water quality will deteriorate. At the same time, the acidic mine water has a strong corrosion effect, and the mine drainage equipment, steel rails, and other auxiliary equipment are continuously corroded, reducing the use of The life span increases the project investment cost. [0003] Currently, a single purification method is usually used for the treatment of acidic mine water. However, due to the large changes in the quality and q...

[0002] Acidic mine water mainly refers to mine water with PH<6. Due to the high content of SO42-, Fe2+, Fe3+, Mn2+ plasma in acidic mine water, when there is hydraulic connection between aquifers, it will cause serious pollution to the groundwater of other aquifers. , when the acidic mine water is directly discharged without treatment and enters the surface water body, the water quality will deteriorate. At the same time, the acidic mine water has a strong corrosion effect, and the mine drainage equipment, steel rails, and other auxiliary equipment are continuously corroded, reducing the use of service life, increasing project investment cost

[0003] Currently, a single purification method is usually used for the treatment of acidic mine water. However, due to the large changes in the quality and quantity of mine water, it is very easy to cause unsatisfactory treatment results. How to solve this problem has become a difficult point in mine water treatment.
