Embodiment 1

[0154] Embodiment one, such as Picture 1-1 and Figure 1-2 As shown, the cross-sectional shape of the housing 1 of the gas dissolving device is rectangular, so the connecting flange on the housing 1 is a rectangular connecting flange. When in use, the pulse current is output to all the electrode plates 2 through the electrical connection line 3, and the pulse current is generated in the sewage through the electrode plate 2 to perform dissolved air treatment on the sewage.

Embodiment 2

[0155] Embodiment two, such as diagram 2-1 , Figure 2-2 As shown, the sectional shape of the casing 1 of the gas dissolving device is circular, so the connecting flange on the casing 1 is a circular connecting flange. Other structures are the same as those in Embodiment 1, and will not be repeated here.

[0156] When a larger scale is required, multiple sets of the above-mentioned Embodiment 1 or / and Embodiment 2 can be connected in parallel to meet the needs.

Abstract

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.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an air-dissolving device which utilizes an electromagnetic (EM) shear field to improve the efficiency of dissolving air in sewage treatment. Background technique [0002] At present, in the sewage treatment technology, it is often necessary to add air, oxygen, chlorine, ozone and other gases into the sewage to achieve the effects of promoting biochemical, chemical reactions, disinfection, etc. The dosing method is basically jet aeration, Aeration pan (pipe) aeration or dissolved air pump and other dosing means, when used, increase the water depth to increase the dissolved air efficiency, the principle is basically to increase the gas solubility by increasing the gas partial pressure. However, the shortcomings of this method are: high energy consumption, low efficiency of dissolved air, and greater influence by temperature and other factors. In addition, the method of increasing water ...
