The physical treatment method is a waste water physical method for separating and recovering insoluble suspended pollutants (including oil films and oil droplets) in waste water by physical action, which can be classified into a gravity separation method, a centrifugal separation method, a screen filtration and interception method and the like, but has poor treatment effect and long treatment time; the chemical treatment method is a wastewater treatment method for separating, removing or converting pollutants in a dissolved or colloidal state in wastewater into harmless substances through chemical reaction and mass transfer. In the chemical treatment method, a treatment unit based on chemical reaction generated by adding a medicament has the defect of generating secondary pollution to the environment; the biological treatment method is a wastewater treatment method for converting organic pollutants in a solution, colloid and fine suspension state in wastewater into stable and harmless substances through the metabolism of microorganisms, but the biological treatment method has certain limitations on the requirements of environment and the quality of wastewater except for long time use. The magnetic field effect can promote the activity of related chemical reactions and substances in the wastewater treatment process, improve the coagulation effect, and the magnetic treatment can destroy the molecular arrangement of the water body structure, reduce the viscosity and enhance the permeability, reduce the water content of the filter residue and improve the purification speed. The contact machine of suspended solids in the water body is increased under the action of a magnetic field, the coalescence speed is improved, the flocculation rate is increased, the magnetic field has the effect that a complex macromolecular system is changed into a simple molecular effect, the reaction activity of the molecules is improved, the magnetic field also increases the activity of groups and the affinity to metal ions, more complex reactions are promoted to be carried out, meanwhile, a double electric layer of colloid is thinned by the magnetic field effect, the adsorption effect is strengthened, therefore, the electromagnetic water treatment does not remove or replace mineral ions in water according to the traditional mode to soften the mineral ions, and chemical preparations are not added into the water, but the effects of preventing scale, killing microorganisms and even removing scale can be achieved.
