Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 , The aeration system for wastewater biochemical treatment in this implementation is mainly composed of a tubular casing 1 , a drive motor 20 and a plurality of ultrasonic vibrating plates 3 . The ultrasonic vibrating plate 3 is composed of an ultrasonic vibrating plate and an ultrasonic generator.

[0022] The casing 1 has a top opening and a bottom opening which communicate with each other; a plurality of ultrasonic vibrating plates 3 are installed in the casing 1 parallel to each other and are arranged close to the top opening. There is a strip-shaped gap 30 between two connected ultrasonic vibrating plates 3 . In this embodiment, the strip-shaped gap 30 is a narrow and long opening in the numerical direction, which is arranged perpendicular to the horizontal plane, and has a long strip-shaped cross section.

[0023] Preferably, the dist...

Abstract

The invention discloses an aeration system for biochemical treatment of wastewater. The aeration system comprises a casing, a driving motor, a stirring impeller and a plurality of ultrasonic vibrationplates, wherein the casing is provided with a top end opening and a bottom end opening which communicate with each other; the ultrasonic vibration plates are mounted in the casing and in parallel with each other in a vertical direction; the driving motor is supported at a bottom end of the casing; and the stirring impeller is driven to rotate by the driving motor. The aeration system provided bythe invention has beneficial effects that air and wastewater are preliminarily mixed by the stirring impeller rotating at high speed, and then the preliminarily mixed wastewater is further ultrasonically mixed by the ultrasonic vibration plates, so that the oxygen dissolving efficiency of the wastewater is improved; and a mode of combining ultrasound with stirring is adopted, so that rotating speeds of transmission parts and the stirring impeller of the equipment are reduced, and the equipment is not easy to be damaged and high in operation efficiency.

Description

technical field [0001] The invention relates to mechanical manufacturing technology, in particular to an aeration system for wastewater biochemical treatment. Background technique [0002] At present, in the field of sewage treatment, the traditional activated sludge biochemical treatment process is dominant, especially in municipal and large-scale industrial sewage water treatment projects, the biochemical treatment process is the core part of the entire project, and the core of the biochemical treatment process is Aeration equipment, through the aeration equipment, maintains a certain dissolved oxygen content in the sewage and makes the dissolved oxygen evenly distributed, and makes the beneficial microorganisms in the activated sludge survive and reproduce, so as to achieve the purpose of decomposing harmful substances such as COD and BOD in the sewage . [0003] Sewage treatment devices in the prior art usually use stirring and submerged diffusion aerators, which dissol...
