Abstract

The invention discloses an acid mine wastewater treatment device for energy saving and emission reduction. The acid mine wastewater treatment device includes a base, an energy saving mechanism, and a mixing pool. The base is sequentially provided with a storage tank, a water inlet pipe, an energy saving Mechanism, mixing tank, sedimentation tank, water inlet pipe, energy-saving mechanism, mixing tank, sedimentation tank are arranged in the base from left to right, the energy-saving mechanism obtains power from the water inlet pipe, and the energy-saving mechanism controls the discharge flow rate of the storage tank, The mixing pool mixes the acidic wastewater and the alkaline solution. The invention is scientific and reasonable, and is safe and convenient to use. When the acidic wastewater flows through the water inlet pipe, the energy-saving mechanism controls the discharge flow rate of the alkaline solution in the storage tank according to the water flow of the wastewater. Make the acidic wastewater and alkaline solution reach a certain neutralization ratio. When the acidic wastewater flows out of the water inlet pipe, the mixing tank can obtain hybrid power through the gravitational potential energy, and the acidic wastewater and alkaline solution can be mixed through the mixing tank to shorten the neutralization of the acidic wastewater. time.

Description

technical field

[0001] The invention relates to the technical field of mine wastewater treatment, in particular to an acid mine wastewater treatment device for energy saving and emission reduction. Background technique

[0002] During the mining of coal mines or various non-ferrous metal mines and the stacking of waste ores, the pyrite associated with the ore bed is often exposed to the air and groundwater or surface water. Through a series of chemical and biological oxidation processes, the near-neutral groundwater is transformed It is acidic mine wastewater with low pH, high Fe, SO42-, and coexistence of various heavy (like) metal ions (Cd, Pb, Cu, Zn, As, etc.). Acid mine wastewater has the characteristics of complex pollution components, large fluctuations in water volume, scattered discharge points, and difficulty in control. If such wastewater is discharged randomly without effective treatment, it will seriously pollute surface water and land resources, and threaten cr...
