Gas dissolving device for improving gas dissolving efficiency of wastewater treatment by using electromagnetic shear field

The invention discloses a gas dissolving device for improving gas dissolving efficiency of wastewater treatment by using electromagnetic shear field. The device comprises a shell; a plurality of electrode plates are distributed in the shell side by side; the electrode plates are alternately divided into two groups; and the two groups of electrode plates are equipped with electric connecting lines. The device also comprises an EM module pulse power system comprising an L-C resonant constant current charging circuit, a two-level charge and discharge circuit, a pulse width modulator and a pulse compression circuit. The invention uses magnetic shear field (electromagnetic shear narrow pulse) to act on cluster structure of water molecules and pollutants in wastewater, change the physical and chemical properties of wastewater, and improve the efficiency of gas dissolving and reaction speed of chemical and biochemical reaction; under the same efficiency, the device can lower energy consumption by more than 50%; besides, the device has a volume only 1/10 of a gas dissolving device in the prior art, thus saving a lot of raw materials.
