Evenly add materials: The intelligent dissolved air flotation sewage treatment device evenly puts polyaluminium chloride and polyacrylamide solution into the stirring chamber through the connection between the drug feeding structure and the stirring chamber. The stirring structure (such as stirring rod and stirring plate) in the stirring chamber is driven by a motor, which can effectively mix the drug solution and wastewater, ensuring that the added drugs are fully contacted and mixed with the wastewater, so that the suspended matter is easier to flocculate.

Facilitates the flocculation of suspended matter: In the stirring chamber, the suspended matter and the liquid medicine are fully mixed through the stirring structure, from hydrophilic to hydrophobic, which is conducive to the flocculation process of the suspended matter. In addition, the bubble chamber and bubbler in the structural design also play an important role. The bubbler generates a large number of bubbles through the ejected compressed air, which can attach the suspended matter in the water and bring it to the surface of the water. In this way, the suspended matter is easier to be captured and separated, and the flocculation efficiency is improved.

High scraping efficiency: The scraping structure in the device is uniquely designed, including a heightening plate, a screw reciprocator, a cross plate and a scraper.
