Problems solved by technology

In this process, chemicals are placed at the bottom between every two levels of interception dams to treat acid mine wastewater. Heavy metal ions in acid mine wastewater will cover the surface of chemicals after reaction and precipitation, resulting in the failure of subsequent wastewater to react with chemicals and After sedimentation, the sediment cannot be separated and pumped out in time

Abstract

The invention discloses a treatment system for acid mine water gushing, which comprises a first permeable dam, a second permeable dam, a biological turntable, and a third permeable dam arranged sequentially along the water flow direction of the acid mine water gushing river or waterway. The permeable dam, the second permeable dam, and the third permeable dam are all arranged across the river or the waterway, and the biological turntable is rotatably mounted on a support frame, and manganese-oxidizing bacteria are loaded on the biological turntable. The invention also provides a treatment method for acid mine water gushing. The present invention can effectively remove heavy metal ions and sulfate radicals in acidic mine wastewater, and at the same time strengthen the Mn 2+ removal effect.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment in the field of environmental protection, and more particularly, relates to a system and method for treating acid mine gushing water. Background technique [0002] Acid mine water gushing is one of the most serious environmental problems faced by the global mining industry, and this problem is also quite prominent in my country. my country has a large number of coal mines and non-coal mines, with 82,000 large-scale mines in production. In many provinces such as Guizhou, Yunnan, Hubei and Hunan, some coal mines and non-coal mines are associated with pyrite. After such mines are mined, due to the contact of pyrite with air and water, the original reducing environment becomes oxidized. In the environment, under the action of microorganisms, the iron and sulfur elements in the ore are further oxidized to produce ferric ions, sulfate ions and a large amount of hydrogen ions (acidic). The...
