Abstract

The invention relates to an underground production wastewater treatment and recycling system, and belongs to the technical field of wastewater treatment. According to the underground production wastewater treatment and recycling system, a wastewater storage tank is sequentially connected with a jet flotation machine, a grid, an aeration tank, a comprehensive regulation tank, a coagulative precipitation tank, a pH regulation tank, an EGSB anaerobic reactor, an inclined plate precipitation tank, an ozone sterilization tank and a reverse osmosis treatment tank; the pipeline for connecting the EGSB anaerobic reactor and the inclined plate precipitation tank is also connected with the top of the EGSB anaerobic reactor; the EGSB anaerobic reactor is also sequentially connected with a gas storage tank and a biogas generator; the aeration tank, the coagulative precipitation tank, the EGSB anaerobic reactor, the inclined plate precipitation tank and the ozone sterilization tank are all connected with a sludge concentration tank. The system is simple in structure, achieves standard discharge of mine wastewater, achieves recycling of the mine wastewater, reduces the production cost, saves energy and is environmentally friendly.

Description

technical field [0001] The invention relates to an underground production wastewater treatment and reuse system, which belongs to the technical field of wastewater treatment. Background technique [0002] During the mining process of the mine, a large amount of mine wastewater will be produced and discharged. The mine wastewater is mainly from the underground geological seepage during the mining process to the natural groundwater discharged from the roadway for safe production and sprinkling, dust reduction, and fire extinguishing during the underground coal mining production process. Waste water containing coal dust produced by grouting, fire fighting and hydraulic equipment. Therefore, it not only has the characteristics of groundwater, but is also polluted by man. [0003] Because some coal dust and rock dust exist in the water in a colloidal dispersion state, the mine wastewater is gray-black, and it is also polluted by human waste, and the number of bacteria generally ...
