Problems solved by technology

There are many types of existing aerators, such as diffuse flow aerators, rubber membrane microporous aerators, tube aerators, Jinshan type aerators, etc., but all of them have low oxygen utilization and power efficiency. , the rubber is easy to age, crack and other disadvantages, the microporous aerator has better oxygenation performance and high efficiency than the large and medium bubble aerator, but for the sewage with high organic load, there are defects such as the microporous aerator’s oxygenation performance is not high

Embodiment Construction

[0019] The ultra-microporous aerator proposed by the present invention, which is applied to the treatment of sewage with high organic load, is described in detail below in conjunction with the accompanying drawings and examples.

[0020] like figure 1 As shown, according to an embodiment of the present invention, an ultra-microporous aerator for high organic load sewage treatment includes a corundum aeration disc 1, a sealing ring 2, an aeration disc support seat 3, and an aeration tube 4 , threaded interface 5, aerator base 6. The corundum aeration disc 1 is an inverted disc-shaped structure, which is fired at high temperature with 40 mesh corundum sand. The aeration disc 1 is evenly perforated with uniform holes. The aeration aperture of the corundum aeration disc is 75 ~ 100μm, the diameter of the generated bubbles is 0.5 ~ 1mm, the airflow is evenly distributed on the entire diaphragm during work, so that the airflow and sewage can be in stable and comprehensive contact. ...

Abstract

The invention relates to an ultramicropore aerator used for high organic load sewage treatment, which comprises an aeration disc sheet (1), an aeration disc sheet support seat (3), an aerator pipe (4) and an aerator base (6), wherein the aeration disc sheet (1) is arranged on the aeration disc sheet support seat (3) via the aerator pipe (4); the aerator pipe (4) is communicated with an air pipeline (7) via the aerator base (6); and the aeration disc sheet (1) has the aperture of 75-100mu m. In the ultramicropore aerator used for high organic load sewage treatment, the aeration aperture of the aeration disc sheet (1) is 75-100mu m, and the diameter of the generated bubble is 0.5-1mm, thus improving the oxygen utilization rate; and a tapered threaded coupling is adopted between the aerator base and the aerator, thus enhancing the tightness between the aerator base and the aerator, preventing air leakage, and facilitating the connection, disassembly, maintenance and replacement of the aerator.

Description

technical field [0001] The invention relates to an aerator for sewage treatment, in particular to an ultramicroporous aerator applied to sewage treatment with high organic load. Background technique [0002] At present, when biochemically treating sewage, whether sufficient dissolved oxygen can be provided is the key to improving the effect of biochemical treatment and economic benefits. There are many types of existing aerators, such as diffuse flow aerators, rubber membrane microporous aerators, tube aerators, Jinshan type aerators, etc., but all of them have low oxygen utilization and power efficiency. , the rubber is easy to age, crack and other disadvantages, the microporous aerator has better oxygenation performance and high efficiency than the large and medium bubble aerator, but for the sewage with high organic load, there are defects such as the microporous aerator’s oxygenation performance is not high. Contents of the invention [0003] (1) Technical problems to...
