Embodiment Construction

[0020] figure 1 It is a schematic diagram of a separation and purification device for treating waste by using superconducting HGMS technology according to the present invention. The waste water enters the reaction tank one 1 from the water inlet one 8 . The adsorption device 1 6 rotates at a certain speed in the wastewater, and the pollutants in the water are quickly adsorbed by the adsorbent under the action of the superconducting high gradient magnetic field. After the adsorption reaction is completed, the adsorption device-6 is pulled and lifted by the support shaft 14 and moved to the desorption chamber-2 for desorption. The adsorption device 2 7 in the desorption chamber 2 3 is moved to the reaction tank 1 1 to continue treating the wastewater. The treated water is discharged from the water outlet one 9. During the desorption process of the desorption chamber 1 2 , the generated waste water enters the sloping plate sedimentation tank 1 4 . The adsorption device 1 6 a...

Abstract

The invention discloses a separate purification device for processing waste by a superconductivity high-gradient magnetic separation (HGMS) technology, and belongs to the fields of resources and environment. Three devices are the same in the reaction process; wastewater enters a reaction tank; and an adsorption device rotates at a certain rotating speed after stopping for a period of time, and fully contacts the wastewater. The adsorption device is lifted and moved to a desorption chamber to desorb after reacting for a period of time as to the device 1 in the desorption process; another group of desorption device is removed to the reaction tank to continuously process wastewater; the adsorption device does not need to lift as to a device 2 and a device 3; the adsorption device in the device 2 synchronously moves; and the reaction tank and the adsorption device in the device 3 synchronously move. Desorption is carried out by the methods such as vacuum adsorption and micro-wave desorption. The adsorbing material and high-gradient magnetic separation technology are fully utilized; the adsorption effect is enhanced; a superconducting magnet is prevented from stopping for a period of time so as to take down, desorb and install the adsorption device; and then the magnetic body is excited. Thus, the time is saved; the cost is reduced; and the treatment efficiency is improved.

Description

[0001] Technical field: [0002] The invention belongs to the field of resources and environment, and relates to a separation and purification device using superconducting HGMS (High Gradient Magnetic Separation) technology, which can realize waste treatment and resource utilization. It is suitable for the treatment and resource utilization of pollutants in metallurgy and chemical industries, especially for the treatment and reuse of acidic heavy metal wastewater. Background technique: [0003] Environmental pollution and resource shortage have seriously affected people's life and production, and the purification of industrial waste has become an urgent problem to be solved. [0004] At present, there are still a large amount of valuable substances in the wastes discharged in industrial production, and it is urgent to find a treatment device that can not only realize the harmless treatment of wastes, but also realize the recovery and reuse of valuable substances. For the...
