Problems solved by technology

This kind of aerator solves the problem of foreign matter entering the pipeline in the existing aerator in a short period of time. However, if it runs for a long time, the rubber vibration diaphragm will age or saccharify, which will easily cause blockage, making it difficult to operate. Stablize

Abstract

The invention discloses a curved surface aerator and an aeration method. The curved surface aerator comprises a curved surface disc, a rotary cutter and an air flow subduction structure, wherein the rotary cutter is arranged below the curved surface disc; the air flow subduction structure is arranged below the rotary cutter; the rotary cutter and the air flow subduction structure are fixedly mounted on a base body; an air inlet channel is formed in the base body; the air inlet channel of the base body is communicated with the air flow subduction structure and an air channel in the rotary cutter in sequence; an air-water contact cylinder is arranged on the base body in a sleeving manner; the air-water contact cylinder is bent and extends upwards in an annular manner; the curved surface disc and the air-water contact cylinder are arranged opposite to each other; a bubble cutting structure is arranged between the curved surface disc and the air-water contact cylinder; the bubble cutting structure is used for cutting bubbles from the rotary cutter. The curved surface aerator disclosed by the invention is uniform and stable in bubble distribution, appropriate in size and reliable in property.

Description

technical field [0001] The invention relates to a curved surface aerator and an aeration method, belonging to the field of aeration equipment at the bottom of sewage and wastewater. Background technique [0002] The aerator is an essential equipment for drainage aeration and oxygenation, and a sharp tool to improve the activity of aerobic microorganisms in sewage. In sewage treatment, the quality of aerator equipment and the quality of its operation directly affect the efficiency and operating costs of sewage treatment, and even affect the success or failure of the entire sewage treatment system. [0003] At present, the commonly used bottom aeration technology adopts microporous aerators, which use the idea of ​​small hole interception to open and close aeration. The size of the opening and closing of the orifice diaphragm determines the size of the bubbles, and the smaller the bubbles in water , the larger the contact area with water, the higher the efficiency of oxygen t...
