Coal washing wastewater generated during the production process contains large amounts of suspended solids (such as coal slime, coal dust, and clay particles), dissolved inorganic salts, and some organic matter. If discharged directly without treatment, it not only causes serious water pollution and wastes resources, but also impacts the company's sustainable development and compliance with environmental standards. Currently, the wastewater treatment method commonly used in coal washing plants primarily involves a process of concentration and sedimentation followed by filter press dehydration and water reuse. The core concept is to remove large suspended solids from the wastewater using a sedimentation tank or thickener, then use a filter press to dehydrate the wastewater into a coal slime cake, and return the clarified water to the system for recycling.
