Treatment system of beneficiation wastewater

Abstract

The invention discloses a treatment system of beneficiation wastewater. The system comprises a water collecting well, a coarse screen, a primary sedimentation tank, a pH value adjusting tank, a carbon dioxide vortex convection scum separation reactor, an aeration tank, a biological oxidation filter tank, a secondary sedimentation tank and a water purification tank. According to the system, the rotational flow attachment effect in the fluid mechanics is utilized creatively, when a liquid in a container has vortex motion, if reverse rotation power is applied to the center of a vortex to produce a reverse vortex, barium ions in the liquid can have the rotational flow attachment effect and gradually converge in a narrow area between the inside reverse vortex and the outside forward vortex, local ion concentration is increased, then carbon dioxide gas is introduced to be dissolved in the liquid to form carbonate ions, the barium ions can be combined with the carbonate ions, insoluble barium salt precipitates are produced and float along the narrow area between the two vortexes, barium salt scum is formed finally, so that the barium ions in the liquid are difficult to remove.

Description

technical field [0001] The invention relates to a treatment system for ore dressing wastewater, which belongs to the field of wastewater treatment in environmental protection. Background technique [0002] Mineral resources are an important material basis for the development of human society and the construction of the national economy. Mining is the industry with the longest history in my country, and it is also the basic industry for the development of the national economy. It involves agriculture, light industry, chemical industry, metallurgy, machinery, construction, energy, Many fields of transportation, national defense and people's daily life. It can be seen that the mining industry plays an irreplaceable and important role in the development of my country's economy. However, during the mining process, mines require a large amount of production water, and at the same time discharge a large amount of wastewater. The indicators such as the concentration of heavy metal i...
