Abstract
The invention discloses a coal mining area wastewater treatment recycling system, belonging to the technical field of water treatment and relating to a system for treating mine water. Shortcomings still exist in the mine water treatment recycling process, and wastewater in the mining area cannot be completely treated and recycled. The coal mining area wastewater treatment recycling system is characterized by comprising a clean mine water recycling subsystem, a high salinity mine water treatment recycling subsystem, an acidity mine water recycling subsystem, a suspended matter containing mine water recycling subsystem, a coal washing wastewater recycling subsystem and a domestic wastewater treatment recycling subsystem. The recycling subsystems are connected with each other and complement each other, so that production wastewater and domestic wastewater in the coal mining area are recycled, and the technical effect of the zero release of wastewater in the coal mining area is achieved. The coal mining area wastewater treatment recycling system is simple in structure. The construction and operating expenses of a part of facilities for wastewater treatment are reduced.
Description
【Technical field】 [0001] The invention belongs to the technical field of water treatment, in particular to a system for treating mine water 【Background technique】 [0002] During the mining process of underground mines, quite a few mines will produce mine water with different characteristics, such as: conventional mine water, high salinity mine water, acid mine water, and special polluted mine water. Generally, these mine waters cannot be directly recycled, and if they are directly discharged into the environment without treatment, they will cause pollution hazards to the environment. At the same time, coal mines need to supply a large amount of water for spraying and dust suppression, clean coal washing, bathing and daily drinking during the production links and periods of mining, transportation, coal washing, mining area greening, sanitation, and employee bathing. Such a row of one supply increases the consumption of water resources in both directions. Therefore, it is a ...
