A modular acid mine wastewater treatment equipment

Abstract

The invention discloses a modular acid mine wastewater treatment equipment, belonging to the technical field of wastewater treatment, which includes a flocculation sedimentation tank, a regulating tank, a clear water tank and a control room connected to each treatment tank, the flocculation sedimentation tank and the inlet The water port is connected, the flocculation sedimentation tank is connected to the adjustment tank, and the adjustment tank is connected to the clear water tank. The first adjustment module is arranged in the adjustment tank. The first adjustment module includes an installation frame, and the first storage part is arranged in the installation frame. The storage part is filled with a first mixture, the first mixture is a mixture of sludge charcoal, organic fertilizer and palygorskite, a second adjustment module is arranged below the first adjustment module, and the second adjustment module includes a second storage part, The second storage part is filled with the second mixture, and the second mixture is a mixture of limestone, zero-valent iron, and biological bacteria agent; the clean water pool is provided with a drain pipe, and the clean water pool is provided with a third water lift pump and the third water lift pump The outlet pipe is connected with the flocculation sedimentation tank.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a modular acid mine waste water treatment equipment, which is suitable for efficient treatment of acid mine waste water and treatment of acid mine water inrush. Background technique [0002] Acid mine wastewater is a wastewater with a low pH that is formed when the metal sulfides in the ore are oxidized under the combined action of air, water, and microorganisms during mining or ore accumulation. Acid mine drainage is extremely acidic and can leach a variety of metal ions such as manganese, magnesium, aluminum, copper, lead, sodium, nickel, calcium and trace metals from residual ore bodies, waste rock piles, soils and sediments The concentration is very high, the pH value is about 2, the iron content is more than 6000 mg / L, and the sulfate content is more than 24000 mg / L. When acid mine wastewater comes into contact with underground aquifers, lakes, rivers, or othe...

Problems solved by technology

There are still many problems in the treatment of acid mine wastewater: (1) For abandoned mines, the cost of restoration and treatment is particularly prominent because they cannot generate new economic benefits; (2) The treatment measures for most mine acid wastewater are slightly ineffective. Single, unable to fully reduce the impact of acid mine wastewater on the surrounding environment; (3) The implementation of the restoration project lacks a comprehensive preliminary investigation, and there is no comprehensive understanding of the hydrogeological background of the mine, which makes the restoration effect of the restoration project unsatisfactory. Unable to meet expectations
