[0002] In the existing coal mine engineering field, most coal mines are located in water-scarce areas. In order to solve the problem of water shortage in coal mines, the resource utilization of mine water has become the main way to solve the shortage of water resources in coal mines. Among them, the resource utilization of mine water is mainly achieved by using mine water desalination technology, and the mine water desalination technology in the prior art basically uses the reverse osmosis method to desalinate the mine water. Further, generally, a set of reverse osmosis systems will be established corresponding to the reverse osmosis method. In order to ensure the long-term stable and reliable operation of the reverse osmosis system, it is very important to treat the concentrated water scale of the reverse osmosis system. The reason is that after the raw water corresponding to the mine water enters the reverse osmosis system, it is concentrated by the reverse osmosis membrane. The ion product of various substances in the concentrated water scale often exceeds its ion product constant, forming crystals or dirt attached to the surface of the reverse osmosis membrane, which will have a huge impact on the performance and life of the reverse osmosis membrane, and will also have an immeasurable impact on the entire reverse osmosis system. At present, various scale inhibitors are mainly added to delay the occurrence of crystallization or precipitation and protect the normal operation of the reverse osmosis system.
