Ultramagnetic separation water purification technology is a new suspended matter removal technology used in sewage treatment field, which can replace traditional coagulation sedimentation, grit sedimentation and inclined plate sedimentation. Different from the traditional gravity separation process of suspended solids, rare earth permanent magnet technology is used to change passive precipitation into active adsorption fishing, which improves the separation efficiency. The water content of sludge separated by ultramagnetic separation technology is less than 93%. The hydraulic retention time of the process is less than 5 minutes, occupying less land. The installed power of the complete set of equipment for daily treatment of 10000 cubic meters of water is only over 40 kilowatts.
This technology is mainly used for the treatment of continuous casting and steel rolling wastewater in metallurgical industry. Groundwater treatment in coal industry; Non-point source pollution control of "milk flow" in stone industry: river and lake landscape, emergency treatment of rivers and lakes in river regulation industry, underground reinjection water treatment in petroleum industry, etc.
