[0002] There are many ways to treat wastewater, among which air flotation is a physical treatment process that separates suspended solids from water through air bubbles. After the air bubbles are released into the wastewater, they come into contact with the suspended particles in the water and float on their surface, reducing the density of the particles. The buoyancy of the air bubbles causes the suspended particles to form bubbles and rise to the water surface, forming a scum layer. By scraping off the scum layer and recycling the clean water, wastewater treatment can be completed.

[0003] According to the patent publication number CN220467641U, a wastewater treatment air flotation machine is disclosed. The machine includes a base, a dissolved air device installed on the left side of the base, an air flotation tank installed on the right side of the dissolved air device, a slag removal mechanism installed on the upper end of the air flotation tank, and a drive box, a wastewater holding tank, a stirring treatment tank, and a partition plate included in the air flotation tank. The air flotation tank has a water inlet opening on the front upper end, a drainage outlet opening on the right lower end, a first fixed plate installed on the front upper end, a second fixed plate installed on the front right end, and first and second fixed seats installed on the upper part of the front and rear ends.

[0032] Reference Figures 1-6 A smart ecological wastewater treatment device includes a treatment tank 1. The treatment tank 1 has a mixing zone 11, a contact zone 12, and a clear water zone 13. An end baffle 8 is fixed at the end of the treatment tank 1. An adjusting plate 2 is located inside the treatment tank 1, between the contact zone 12 and the clear water zone 13. A dissolved air pipe 3 is located in the contact zone 12. The treatment tank 1 is the outer shell of the ecological wastewater treatment device. The treatment tank 1 is internally divided into a mixing zone 11, a contact zone 12, and a clear water zone 13. The mixing zone 11 and the contact zone 12... The wastewater is separated by a partition, and the contact zone 12 and the clear water zone 13 are separated by an adjusting plate 2. The end of the clear water zone 13 is blocked by an end baffle 8. After entering the treatment tank 1, the wastewater passes through the mixing zone 11, the contact zone 12, and the clear water zone 13 in sequence. In the mixing zone 11, treatment agents can be added to the wastewater. After mixing, the wastewater enters the contact zone 12, where impurities in the mixed wastewater are further treated by air flotation. After the dissolved air water enters the contact zone 12, the pressure rapidly decreases to or near atmospheric pressure due to the reduced gas solubility. Released from the water, it forms a large number of microbubbles. These microbubbles attach to the surface of suspended particles in the wastewater, reducing the particle density and causing them to float to the surface for separation. The contact zone 12 is surrounded by components including, but not limited to, dissolved air pipes 3, aeration heads, compressors, and dissolved air tanks. Air is compressed to a certain pressure by an air compressor and sent into the dissolved air tank. Inside the tank, the air is dissolved into the water under high pressure, forming high-pressure dissolved air water. This dissolved air water is released through the aeration heads within the contact zone 12, generating a large number of microbubbles, thereby achieving… To further explain the role of wastewater treatment, a pipe with a valve is installed at the bottom of the partition between the mixing zone 11 and the contact zone 12. By controlling the valve, the wastewater in the mixing zone 11 can be discharged into the contact zone 12. At the same time, after the wastewater enters the contact zone 12, as the water level rises, the treated liquid flows into the clear water zone 13 along the inclined end of the top of the regulating plate 2. At this time, the wastewater in the clear water zone 13 forms a separation of clear water and scum. After the scum is scraped off, the liquid in the clear water zone 13 can be discharged and recycled.
