Efficient Eco-friendly Treatment System Commissioned at Guping Mining Area

To continuously improve the ecological environment of the mine and realize green, environmentally friendly, safe and efficient mining, the company invested nearly 3 million yuan in 2021 to install a high-efficiency sewage purification system in the Guping Mining Area. Its main facilities include a 600 m³ high-efficiency thickener, dosing and conditioning equipment, filtration and press units, and a clean water tank. Designed to treat wastewater and rainwater mixture generated from stope mining and processing operations, the system pumps collected wastewater to the thickener. Based on the solid content and viscosity of the slurry, automatic solid-liquid separation can be achieved within about 20 seconds. The thickened material flows into a buffer tank through natural sedimentation, and sludge with a solid content of 10%–40% is further dewatered efficiently. This greatly improves the dewatering performance of the filter press. All wastewater is filtered by the filter press and turned into clean water that can be directly discharged or reused.After pressing and separation, the dry sludge residue is stacked and turned waste into wealth.
