Integrated low-power-consumption aeration and oxygenation device for sewage treatment

Abstract

The invention relates to the technical field of sewage treatment, and discloses an integrated low-power-consumption aeration oxygenation device for sewage treatment, the top of an aeration pipe is provided with an air outlet, the top of the air outlet is provided with an inclined aeration nozzle, a support plate is arranged above the inclined aeration nozzle, and the bottom of the support plate is fixedly provided with a fan-shaped blade; according to the device, gas in the aeration pipe is obliquely sprayed to the position of the fan-shaped blade at the bottom of the supporting plate through the oblique aeration nozzle which is obliquely arranged, the bottoming flat plate is in contact connection with the inner bottom of the sewage pool, and the fixing columns are limited on the two sides of the gas outlet through the elliptical arc-shaped hoops and the bottoming flat plate; the inclined aeration nozzles are arranged on the support plate, so that the fan-shaped blades can rotate, the support plate enables the fan-shaped blades to keep stable during rotation through sliding of the circular sliding grooves and the arc-shaped sliding blocks, bubbles sprayed by the inclined aeration nozzles can be diffused through the rotating fan-shaped blades, and sewage can be better contacted and fused with the bubbles.

Description

Technical field [0001] The present invention relates to the field of sewage treatment, in particular a low power consumption aeration oxygenation apparatus for integrated sewage treatment. Background technique [0002] During the sewage treatment, there is a certain method and apparatus to force the air into the sewage, so that the inner sewage is contacted with air, reinforcing the contact of the organic matter in the pool and dissolve oxygen, and oxidize the organic matter in the sewage. [0003] The conventional aeration oxygenation device is ejected through a aerated device to eject a number of aeration bits on the aeration pipe, and the air bubbles discharged from the air junction are tumbling in the water, so that oxygen can be fused with water, but the air nozzle The spray range is limited. If the water is required to fusion, the aeration equipment is required for a long time, thereby increasing the problem of increased power consumption, and proposes a low-power aeration ...

AI Technical Summary

Problems solved by technology

[0003] The traditional aeration and oxygenation device is to spray the gas through several aeration nozzles on the aeration pipe through the aeration equipment, and the bubbles ejected by the gas nozzles are tumbling in the water, so that the oxygen can be fused with the water, but the gas nozzles The range of injection is limited. If the sewage needs to be fully fused with the air bubbles, the aeration equipment needs to work for a long time, resulting in the problem of increased power consumption. Therefore, a low-power aeration and oxygenation for integrated sewage treatment is proposed. device
