Integrated Solution for Efficient Processing and Resource Utilization in Mining Areas encompasses technologies and equipment for underground mine water treatment, zero-liquid-discharge (ZLD) treatment of high-salinity mine water, and domestic sewage treatment in coal mines. The Underground Mine Water Treatment Technologies and Equipment address challenges including frequent sedimentation in water sumps, difficulties in coal slurry dewatering, and substandard water quality for high-purity applications such as emulsion preparation and three-machine cooling systems. These solutions enable clear water storage in sumps, mechanized/automated continuous coal slurry dewatering, and graded treatment/utilization of mine water underground, fulfilling requirements for both recycled water and high-purity process water. The High-Salinity Mine Water ZLD Technologies and Equipment accommodate varying salinity levels and ionic compositions. Featuring compact processes with strong resistance to water quality fluctuations, they deliver high cost-effectiveness with low energy consumption and operational costs. This achieves an eco-friendly transformation from "high-salinity black water" to "purified water and reusable salts," resolving environmental compliance and water supply challenges. The Coal Mine Domestic Sewage Treatment Technologies and Equipment utilize simultaneous nitrification-denitrification with high biomass concentration. Their short-process design requires no backwashing and minimizes footprint, enabling efficient nitrogen removal and advanced treatment under low carbon-to-nitrogen ratio conditions.
