The wastewater generated in the production process is often treated by nanofiltration separation equipment. As an emerging separation and purification technology, the basic principle of nanofiltration separation equipment is to use ultrafine filtration membranes to intercept and filter impurities, colloids, bacteria, etc. in water. The pore size of nanofiltration membranes is generally between 1-100 nanometers, which is finer than traditional filtration membranes. However, in the process of water treatment by nanofiltration separation equipment, due to the small pore size of ultrafine filtration membranes, particulate pollutants rich in water are easy to affect its use, resulting in low water treatment efficiency, and the need for frequent cleaning and maintenance of nanofiltration separation equipment, resulting in certain deficiencies in the use of nanofiltration separation equipment.
