In addition to containing suspended solids mainly composed of coal shavings, the water in many coal mines also has high levels of soluble total solids, total hardness, sulfates, chlorides, fluorides, etc., and must be deeply treated before it can be used as domestic and production water for coal mines. The ion content varies in different mines, and corresponding treatment techniques and process parameters must be adopted through simulation experiments based on the water quality characteristics of a specific coal mine mine water. The deep treatment technology of mine water developed by Shandong AMS mainly includes pre-treatment technology, reverse osmosis treatment technology, and automation monitoring technology. After deep treatment, mine water can be used as drinking water for coal mine life, canteen water, boiler water, and other industrial water.
