Sewage oxygen exposure device suitable for advanced environmental protection industry

Abstract

The invention discloses a sewage oxygen exposure device suitable for advanced environmental protection industry, and relates to the technical field of advanced environmental protection industry. The sewage oxygen aeration device suitable for the advanced environmental protection industry comprises an air inlet pipe, the lower end of the air inlet pipe is communicated with a fixing box, the center of the bottom of the inner wall of the fixing box is fixedly connected with a fixing pile, the outer wall of the fixing pile is fixedly connected with four springs, and the ends, away from the fixing pile, of the four springs are each provided with an air conveying mechanism. According to the sewage oxygen aeration device suitable for the advanced environmental protection industry, when airflow passes through the water inlet pipe, a part of water flows into the upper side of the water inlet pipe, so that the water and the airflow are mixed to pass through the fan blades, rotation is pushed, and bubbles are broken by the fan blades; according to the invention, the movement track of bubbles in water can be prolonged when the bubbles are ejected from the right end of the secondary compression cylinder, and the purpose that the bubbles generated during aeration are not easy to form large bubbles is achieved due to simultaneous ejection of water flow, and the aeration efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of advanced environmental protection industries, in particular to a sewage oxygen exposure device suitable for advanced environmental protection industries. 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 The aeration system is to continuously provide a large amount of oxygen to the pool. The current aeration system has many forms, and various forms of aeration systems will always produce a large number of large bubbles during the aeration process. The air bubbles are difficult to dissolve in the water, and they basically float directly to the water surface without increasing the oxygen content of the pool water. Howev...

[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 The aeration system is to continuously provide a large amount of oxygen to the pool. The current aeration system has many forms, and various forms of aeration systems will always produce a large number of large bubbles during the aeration process. The air bubbles are difficult to dissolve in the water, and they basically float directly to the water surface without increasing the oxygen content of the pool water. However, since the fine air bubbles generated by the aeration system are always close to each other at the beginning, they are extremely easy to attract and merge with each other, forming a pool. Large air bubbles; therefore, for the current aeration system, there will always be a large number of large air bubbles, which will greatly limit the oxygen dissolved efficiency of sewage
