Aeration device for sewage treatment and anti-blocking function

Abstract

The invention relates to an aeration device for sewage treatment and an anti-blocking function. The device comprises a main device body, an air inlet pipe and two or more air outlet pipes, the main device body is cylindrical, and the air inlet pipe and the main device body are coaxially arranged; the axes of the air outlet pipes are vertical to and intersect with the axis of the main device body;air inflation devices are arranged on the air outlet pipes and arranged at one end of the air inlet pipe, and the other side of the air inlet pipe is communicated with the main device body; the air outlet pipes are evenly arranged on the periphery of the main device body with the axis of the main device body as the center in the circumference direction, the air outlet pipes are communicated with the main device body, and an assistance mechanism and an anti-blocking mechanism are arranged in the main device body. According to the aeration device for sewage treatment and the anti-blocking function, through the assistance mechanism, the aeration effect is improved, the uniformity of the air in sewage is improved, and in addition, through the anti-blocking mechanism, the air outlet pipes are prevented from being blocked.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an aeration device with anti-clogging function for sewage treatment. Background technique [0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Among them, the aerator is a common type of sewage treatment equipment. The aerator directly injects microbubbles into the untreated water. In the treated sewage, under the joint action of coagulant and flocculant, the suspended solids undergo physical flocculation and chemical flocculation, thus forming large suspended solids flocs, which float to the liquid surface under the action of the bubble group to form The scum is separated from the water using a scum scraper. [0003] Although the air outlet of the existing aerator will not be blocked during the air outlet process, when the aerator stops running, the impurities in the s...

AI Technical Summary

Problems solved by technology

[0003] Although the air outlet of the existing aerator will not be blocked during the air outlet process, when the aerator stops running, the impurities in the sewage still block the air outlet, which reduces the practicability. Not only that, the existing aerator The aeration method of the aerator is single, resulting in a limited aeration range and aeration uniformity angle, which reduces the aeration effect
