[0002] Coal mine dewatering drainage (also known as mine drainage or mine drainage) refers to the underground water discharged to keep the working space in the mine dry. This drainage may contain various metal oxides, mainly from rock weathering, ore dissolution, water contact, etc. These metal oxides not only pollute the environment but also may affect human health. Therefore, during the process of coal mine dewatering drainage, it is necessary to reduce the emission of metal oxides, remove metal ions from water, and make the treated water quality meet the discharge standard.

[0003] Ultrafiltration equipment is a high-efficiency water treatment device, mainly used to remove macromolecular organic matter, colloids, bacteria, viruses and other particles in water.
