Problems solved by technology

[0005] In the existing aeration device, the installation of the aeration pipes is generally arranged from the long end of the aeration tank body, with a distance of 500mm to 1500mm. In this installation method, due to the large distance between the aeration pipes, there will be problems in the aeration process. Aeration blind area, that is, some areas where the aeration bubbles cannot reach. During the aeration process, the volume of the bubbles is large, and the bubbles will be larger after colliding and pooling. The air spacing, the dissolved oxygen concentration in the aeration area is seriously uneven

Embodiment Construction

[0028] In order to better understand the technical solutions of the present invention, the following will be described in conjunction with specific embodiments:

[0029] See figure 1 with figure 2 , figure 1 is the front view of the aeration device provided by the embodiment of the present invention, figure 2 It is a top view of the aeration device provided by the embodiment of the present invention.

[0030] As shown in the figure, there is a blast main pipe 15 at the top of the air intake end of the aeration tank, and a hole is opened on the side of the aeration main pipe 15, and a short pipe at one end is welded to the opening, and then the control valve 14 is connected to the control valve 14. The opening of the aeration can control the size of the aeration air flow. The elbow and other connecting parts are welded on the control valve 14. The blast branch pipe 12 is connected to the blast main pipe 15 on the upper part of the aeration tank through a slipknot 13. The l...

Abstract

The invention discloses an aerating device which comprises an air allotting device and a plurality of aerating pipes, wherein the air allotting device is communicated with the aerating pipes; and aerating micropores are arranged on the aerating pipes. The aerating device is characterized in that a distance between the adjacent aerating pipes is from 80 mm to 300 mm, and at least 2,000 aerating micropores are arranged on each aerating pipe. Compared with the prior art, the aerating device has 80 mm to 300 mm of distance between the adjacent aerating pipes and reasonable aerating pipe distance setting, improves oxygenation efficiency, and can not only reduce aerating power consumption, but also eliminate an aerating blind zone, lead dissolved oxygen concentration in sewage to be more balanced and supply a softer growing environment to microorganisms so as to more effectively and thoroughly remove various pollutants in water.

Description

technical field [0001] The invention relates to a sewage treatment device component, in particular to an aeration device, belonging to the technical field of water treatment. Background technique [0002] With the development of society, the problem of shortage of water resources is becoming more and more serious, and water will become an important factor restricting social development. People are also paying more and more attention to the development and improvement of water treatment technology. [0003] The sewage biological treatment process is a special kind of sewage treatment process, also known as the activated sludge process. Activated sludge process can be divided into aerobic method and anaerobic method. In the aerobic biological sewage treatment system, microorganisms use dissolved oxygen in water to oxidize and degrade organic pollutants in water, and then separate microorganisms and water to achieve the purpose of purifying sewage. The English name of dissol...
