Description
The development of cryogenic technology has greatly reduced the cost of large-diameter superconducting magnets and the difficulty of operation, making it possible for industrial fields. Our team has developed a large-diameter (room temperature aperture of more than 400 mm) superconducting magnet with direct-conduction cooling by a single GM refrigerator, which has improved the cooling efficiency, thermal stability and safety of the superconducting magnet, and it has been adapted in wastewater treatment. Based on the strong magnetic field generated by the superconducting magnet as well as carefully designed magnetic gradient, a series of devices have been developed and applied in several projects in China. In addition, an automated, continuous high-gradient magnetic separation system, as well as a cleaning system and a magnetic species recovery system have been developed to achieve efficient, continuous and stable operation of device. Furthermore, an integrated superconducting magnetic separation wastewater treatment device has been formed through integrated design, which has demonstrated significant performance on chemical oxygen demand (COD), total phosphorus and suspended solids.
