Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a high-efficiency air-floating sewage circulation treatment device. Background Art

[0002] When the sewage (waste) water discharged from the pollution source contains a high total amount or concentration of pollutants, fails to meet the discharge standards or does not meet the environmental capacity requirements, thereby reducing the water environment quality and functional objectives, it must undergo artificial intensive treatment. This place is a sewage treatment plant, also known as a sewage treatment station. At present, sewage treatment plants usually use flotation water treatment processes to treat suspended pollutants. However, the existing pollution removal devices of this type still have certain disadvantages when they are used. For example, the flotation method forms tiny bubbles in the flotation tank, which quickly attach to the suspended matter and lift it to the surface of the flotation tank. However, not all suspended matter will be brought to the surface of the flotation tank by the bubbles at once. Therefore, there will be suspended matter residues in the discharged sewage, which will result in poor sewage treatment effects, causing certain adverse effects in actual use.

[0003] According to the patent publication number CN210505790U, a device for rapidly removing suspended pollutants in a sewage treatment plant is provided, which includes a flotation tank, a scraper is fixedly installed at the top position of the inner surface of the flotation tank, a pressure gas tank is fixedly connected to the upper surface of the flotation tank, a booster pump is fixedly connected to the upper end of the pressure gas tank, a sewage inlet pipe is fixedly connected to the upper surface of the booster pump, an air compressor is fixedly connected to the outer wall of one side of the pressure gas tank, a release head is fixedly installed at the lower end of the pressure gas tank, a first baffle is fixedly connected to the bottom inner wall of the flotation tank, and a second baffle is fixedly connected to the lower surface of the scraper away from the first baffle. The decontamination device in the utility model adds a filtering and circulating treatment structure, and the sewage cleaned by the flotation method is filtered again, and the sewage can be circulated for multiple times, so that the suspended pollutants in the sewage are thoroughly removed, and the treatment efficiency is faster and the effect is better.

[0004] There are still some shortcomings in this patent application. After running for a period of time, a large amount of residue will remain in the filter tube. The residue will block the micron filter screen, causing the water circulation to be unsmooth, affecting the sewage treatment efficiency. At the same time, the filter tube is located at the bottom of the device, which is difficult to clean and needs to be manually removed, which is very time-consuming. Therefore, an efficient flotation sewage circulation treatment device is needed to solve this problem. Utility Model Content
