Background
In the processes of sewage treatment and purification and the like, the magnetic field can be used for directly degrading organic matters by the action of water, other solvents and dissolved oxygen. The magnetic effect may promote the dissolution of oxygen in water and may generate reactive oxygen species in water. The active oxygen groups have stronger oxidation performance and can oxidize organic matters in water, thereby reducing the content of the organic matters in the water body. And the magnetic field generated by the rotating magnet strip can play a certain stirring role, and organic particles can be attached to the magnetic flocculant, so that pollutants adsorbed on the magnetic powder are subjected to magnetic flocculation and accelerated sedimentation. The water solvent as the medium for organic matter to be treated has certain change in physical property under the action of external magnetic field, and the electrostatic effect, cage effect, etc. of the solvent in the liquid phase chemical reaction process can affect the chemical reaction process to raise the oxidizing and degrading rate of organic matter fast. Particularly in the reaction of photocatalytic degradation of organic matters, the photocatalytic degradation reaction has long time and slow reaction rate, so that the degradation efficiency is low. The magnetic field can greatly improve the reaction rate of photocatalytic degradation of sewage and promote the further degradation of organic matters. In addition, the addition of the magnetic field can not only obtain good treatment effect, but also reduce the introduction of new impurities and certain harmful substances in the treatment process.
When the pollutants in the sewage exist in a colloidal form, the magnetic flocculant is added, and then the flocculated pollutants mixed with the magnetic seeds are adsorbed by a magnetic adsorption mode to achieve the aim of purifying the sewage, which is an effective treatment method at present. The existing magnetic adsorption device generally rotates in a separation box body through a magnetic disc, adsorbs flocculent pollutants mixed with magnetic seeds, scrapes the flocculent pollutants mixed with the magnetic seeds by a scraper blade and outputs the pollutants. However, this device has the following disadvantages: when carrying out the magnetic separation, can not guarantee magnetic adsorbent intensive mixing and magnetic field maldistribution in the sewage to when carrying out the clearance of flocculation form pollutant, can not carry out the effective processing to flocculation form pollutant and magnetism kind and retrieve, lead to the flocculation effect poor, the treatment cost improves, arouses the wasting of resources.
