Coal accounts for over 70% of China's energy structure, and during the coal mining process, a large amount of wastewater is discharged. If discharged directly without treatment, it will inevitably cause serious pollution to the environment and result in a significant waste of water resources. Therefore, the development, management, and utilization of coal mine water resources are of great significance for the sustainable development of the coal industry.
Mine wastewater is generated during the coal mining process by washing the drill bit and by the infiltration of groundwater into the roadway. The mine wastewater is collected in the sewage treatment station through the pipeline network or underground ditch in the mining area. The main pollutants in mine wastewater are suspended solids (SS) and iron, which are typical inorganic wastewater.
NanoMem ceramic flat membrane has the advantages of high flux, small footprint, more stringent water inlet conditions, and convenient operation, maintenance, and management. The wastewater generated during underground production first passes through the raw water tank, and then enters the ceramic flat membrane tank for filtration. The produced water can meet the requirements of deep treatment for discharge and reuse. By adopting this new sewage treatment mode, not only is the construction volume small and the operating cost low, but it also effectively replaces the existing surface sewage treatment facilities and achieves the energy-saving and emission reduction goals of mine construction, playing a positive role in protecting water resources in mining areas.
The treatment and design of coal mine wastewater must follow the principle of sustainable development, and balance immediate and long-term benefits. When treating wastewater, specific operations should be carried out based on the characteristics of the wastewater, combined with the actual production of the mine, and attention should be paid to the use of new technologies and processes to achieve better purification and purification effects in wastewater treatment.
