Abstract

The invention relates to the technical field of water treatment, in particular to micro-nano modified magnetic powder which reduces the specific gravity of traditional magnetic powder, so that the production cost of the magnetic powder is reduced, and the adsorption efficiency of the magnetic powder is further improved. The magnetic powder is prepared from the following raw materials in parts by mass: 5 to 9 parts of magnetic particles, 8 to 12 parts of nano adsorption material, 20 to 25 parts of porous aggregate, 3 to 6 parts of aerosol condensate and 10 to 15 parts of polyethyleneimine.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a micronano-modified magnetic powder. Background technique [0002] In recent years, magnetic separation has become a new water treatment technology. Magnetic separation as a physical treatment technique has been used successfully in water treatment, showing many advantages. Magnetic separation uses the magnetism of impurity particles in wastewater to separate. For non-magnetic or weakly magnetic particles in water, magnetic separation technology is a technology for magnetic field treatment of substances. The application of this technology has penetrated into various fields; [0003] There have been many studies and applications of magnetic separation technology in water treatment, and more and more scholars have paid more and more attention to it; at this stage, most of the magnetic species used in research are expensive ferric oxide or ferrite, and the cost is relative...
