Deep well aeration wastewater treatment device capable of prolonging rising distance of waste gas

Abstract

The invention provides a deep well aeration wastewater treatment device capable of prolonging the rising distance of waste gas, and the deep well aeration wastewater treatment device capable of prolonging the rising distance of the waste gas comprises an aeration pipe, an inner pipe, a sewage pool, an outer well and two flow speed regulation and control assemblies. The sewage pool is arranged on the ground, the outer well is arranged at the bottom of the sewage pool, and the inner pipe is arranged in the outer well. The aeration pipe extends into the inner pipe from the sewage pool. According to the deep well aeration wastewater treatment device capable of prolonging the rising distance of the waste gas, the aeration pipe, the inner pipe, the sewage pool, the outer well and the two flow speed regulation and control assemblies are matched with one another. When sewage touches the bottom and then turns upwards through the flow speed regulation and control assembly, the caliber of the outer shaft is reduced through the flow speed regulation and control assembly, the sewage speed is increased, meanwhile, collision between the sewage is increased by changing the sewage flowing direction, the degassing speed is increased, and people can use the sewage degassing device conveniently.

Description

technical field [0001] The invention relates to the technical field of aeration equipment, in particular to a deep well aeration wastewater treatment device capable of extending the rising distance of waste gas. Background technique [0002] The deep well aeration process has a series of outstanding advantages and has been widely valued. The deep well aeration device is the main equipment of this rapid treatment method. Because the treatment of deep well aeration wastewater generally adopts the airlift cycle powered by compressed air. However, the compressed air injected in the stripping cycle will gradually dissolve into the water as the circulating liquid flow descends. When the mixed liquid flow reaches the bottom of the tank, it changes direction and flows upward along the riser, and the air dissolved in the water is gradually released again. However, traditional deep wells are often straight up and down and have a smooth inner wall surface. Therefore, in order to ensu...

AI Technical Summary

Problems solved by technology

However, traditional deep wells are often straight up and down and the inner surface is smooth. Therefore, in order to ensure the tumbling height of sewage, the depth of the well is relatively deep.
