Regulatory aeration system for wastewater treatment

Abstract

The invention relates to a regulatory aeration system for wastewater treatment. The regulatory aeration system comprises an aeration tank, a water inlet pipe, a water draining pipe, a controller, a top plate and two supporting columns, wherein a driving mechanism comprises a sleeve, a first gear, a regulating mechanism, a plurality of rotating assemblies and two driving assemblies; each rotating assembly comprises a first motor and a second gear; each driving assembly comprises a reciprocating unit, a connecting rack and a supporting rod; the regulating mechanism comprises a lifting assembly,a cross rod, a regulating pipe and a sealing assembly; the lifting assembly comprises a second motor, a bearing, a second driving shaft, a wire reel and a pull wire. According to the regulatory aeration system for the wastewater treatment, in the regulating mechanism, the height position of the regulating pipe is flexibly controlled according to the liquid level of sewage, so that energy consumedduring aeration of an aerator is saved; in addition, aeration heads swing back and forth while the driving mechanism drives aeration mechanisms to rotate, so that bubbles generated by the system act on all parts of the sewage, and the aeration efficiency and the practicality of the system are improved.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to an aeration system with regulating function for sewage treatment. Background technique [0002] Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid, the purpose of which is to obtain sufficient dissolved oxygen. In addition, aeration can prevent the suspended matter in the pool from sinking and strengthen the contact between organic matter in the pool and microorganisms and dissolved oxygen, so as to ensure that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen to achieve sewage purification. Purpose of processing. [0003] The aerator is usually equipped with an air intake pipe to introduce external air into the aerator, but the length of this air intake pipe is usually fixed, so that the aerator needs to be injected into the aeration tank w...

AI Technical Summary

Problems solved by technology

[0003] The aerator is usually equipped with an air intake pipe to introduce external air into the aerator, but the length of this air intake pipe is usually fixed, so that the aerator needs to be injected into the aeration tank when the aerator is in use. Quantitative sewage, when the liquid level of the sewage is too high, the sewage is easy to pass through the intake pipe, and aeration cannot be performed. When the liquid level of the sewage is too low, it will lead to excessive control of the intake pipe, resulting in a large energy consumption for introducing air , Not only that, because the aeration head is fixedly installed at the bottom of the aeration tank, the rising path of the bubbles generated by the aeration head in the sewage is fixed, resulting in a limited range of action of the aeration head, and the aeration tank takes a long time time to complete wastewater treatment, further reducing the usefulness of existing aeration systems
