Embodiment Construction

[0033]The invention has a cylindrical shape and is composed of an air inlet pipe, an inner cylinder, an outer cylinder, an air nozzle, a water pan, a diffusion pipe, a crushing chamber, a dispersion disk, a sawtooth retaining ring, a concave retaining ring, a disturbing rod and other components. The device is installed at the bottom of the aeration tank of the sewage plant to replace the existing microporous aeration device (head).

[0034] The air intake pipe 4 is connected to the existing aeration system air pipe of the sewage plant through the joint 18. The pressurized air in the air pipe enters the air intake pipe 4 and is sprayed out through the air nozzle 2 to generate high-speed rotation and be magnetized by the magnet 6. The air The polarity is more stable. The water in the aeration tank enters the inner cylinder 7 of the device through the opening on the bottom 5 of the inner cylinder and the lower cover 15 of the outer cylinder. The water pressure in the inner cylind...

Abstract

The invention relates to a blocking-proof micro-bubble aeration device, which is used for oxygen aeration of an aerobic treatment section in a sewage treatment process. The device is cylindrical, and comprises the structures of an inner barrel, an outer barrel, an air inlet pipe, an air nozzle, a water plate, a diffusing pipe and the like, wherein a crushing chamber and a snakelike waterway are formed between barrel walls of the inner barrel and the outer barrel, an air-water mixture enters the crushing chamber and the snakelike waterway via the diffusing pipe, and repetitive multi-time impact crushing and disturbing and dispersing are carried out, so that micro bubbles are generated. According to the device, the micro bubbles are not generated by extruding compressed air through micro holes in the surface of the aeration device (head), thus, the micro holes are not formed in the surface and interior of the device, and the problem of blocking is prevented from occurring.

Description

technical field [0001] The invention is an anti-clogging micro-bubble aeration device, which is used for the aeration and aeration of the aerobic treatment section in the sewage treatment process. Background technique [0002] Aeration is an important process in the sewage treatment process. Under the same ventilation rate, the aeration efficiency has a positive correlation with the oxygen utilization rate of the aeration device. The higher the oxygen utilization rate, the higher the aeration efficiency. The oxygen utilization rate is related to the particle size of the bubbles generated by the aeration device. The smaller the bubble size, the higher the oxygen utilization rate. Aeration efficiency affects the energy consumption and cost of sewage treatment. The higher the aeration efficiency, the lower the energy consumption and treatment cost per ton of sewage. [0003] In order to obtain higher aeration efficiency, the aeration system currently used in sewage treatment ...
