Problems solved by technology

However, since the fine air bubbles generated by the aeration system are always close to each other at the beginning, it is extremely easy to attract and merge with each other to form large air bubbles; Oxygen efficiency is more limited

Embodiment 1

[0015] exist figure 1 In the first example shown, the high-efficiency dissolved oxygen sewage aeration tank includes a tank body (not shown) and an aeration system; the aeration system includes an air supply source 1, an air supply pipeline 2, and evenly distributed in the tank The microporous aeration head 3 in the body; the airflow output by the air supply source 1 is transported to each microporous aeration head 3 through the air supply pipeline 2, and forms air upward through the micropores on the top of the microporous aeration head 3. Fine bubbles; an electrostatic tube 4 insulated and connected to the gas supply pipeline 2 is also connected in series between the gas supply pipeline 2 and the gas supply source 1, and a corona wire 41 extending along the axis is arranged inside the static tube 4, The corona wire 41 is electrically connected to the first electrode of a high-voltage power supply 5; the end of the electrostatic tube 4 close to the gas supply source 1 is also...

Embodiment 2

[0019] for figure 2 The second embodiment shown is different from the first embodiment in that an excitation solenoid 7 is sheathed on the outside of the electrostatic tube 4, so that an axial magnetic field is generated in the electrostatic tube 4; thus, the electrostatic tube 4 When the charged dust inside moves radially outward, it will be deflected around the axis by the Lorentz force, thereby significantly inhibiting the charged dust from flying to the tube wall of the electrostatic tube 4; the electrostatic tube 4, the gas supply pipeline 2 and The inner wall of the microporous aeration head 3 is also provided with a layer of antistatic film to prevent the charged dust from losing charge after hitting the inner wall of each component.

[0020] In addition, the air supply source 1 adopts an air pump with automatic power adjustment, and the air pump continuously fluctuates the air supply rate according to the setting; and the corona wire 41 is composed of a spring wire, a...

Abstract

The invention provides an efficient aeration tank for dissolved oxygen sewage. The efficient aeration tank comprises a tank body and an aeration system; the aeration system comprises an air supply source, an air supply pipeline and microporous aeration heads uniformly distributed in the tank body; an airflow of the air supply source is delivered to each of the microporous aeration heads by the air supply pipeline and upwards forms fine air bubbles by micropores in the upper parts of the microporous aeration heads; an electrostatic pipe connected with the air supply pipeline in an insulating way is also connected in series between the air supply pipeline and the air supply source, the electrostatic pipe is internally provided with a corona wire extending along an axis, and the corona wire is electrically connected to a first electrode of a high-voltage power supply; and a dust vessel is also connected beside the end, close to the air supply source, of the electrostatic pipe, and dust in the dust vessel is sucked by the airflow when the airflow is formed in the air supply pipeline and the electrostatic pipe. The aeration tank for sewage can be used for inhibiting the production of large air bubbles to a great extent, so that the aeration effect is improved, and the dissolved oxygen efficiency is increased.

Description

technical field [0001] The invention relates to the field of sewage treatment facilities, in particular to a sewage aeration tank. Background technique [0002] In the sewage treatment system, it usually includes biochemical treatment process. Generally, aerobic bacteria pool and anaerobic bacteria pool are configured; for aerobic bacteria pool, in order to improve the activity of aerobic bacteria and ensure the effect of biochemical reaction, it is necessary to set up Aeration system to continuously provide a large amount of oxygen to the pool. [0003] For the current aeration system, there are many forms, and various forms of aeration systems will always produce a large number of large air bubbles during the aeration process. Such large air bubbles are difficult to dissolve in water and basically directly surface. , and will not promote the oxygen content of the pool water. However, since the fine air bubbles generated by the aeration system are always close to each oth...
