Construction and working process
The GF type combined air flotation equipment consists of components such as an air flotation tank, a dissolved gas system, a dissolved gas reflux pipeline, a dissolved gas water release device, a slag scraping device (which can be used in combination, crane type, and chain plate type according to user needs), and an electrical control cabinet. Air flotation separation technology refers to the process of allowing air and water to dissolve into water to a greater extent under a certain working pressure, striving to be in a saturated state. Then, the formed pressure dissolved water is released through pressure reduction, producing a large number of fine bubbles that fully contact the suspended flocs in water. This allows the suspended flocs in water to adhere to the micro bubbles and float to the water surface together with the bubbles, forming scum and scraping off the scum, thereby purifying water quality. Air flotation mainly plays a role in solid-liquid separation (while reducing COD, BOD, chromaticity, etc.). After adding flocculants PAC or PAM to the raw water and undergoing effective flocculation reaction (time, dosage, and flocculation effect must be determined experimentally), the raw water enters the combined air flotation contact area. In the contact area, the microbubbles in the dissolved water adhere to the flocs in the raw water and enter the separation zone together. Under the buoyancy of the bubbles, the flocs and bubbles rise to the liquid surface together, forming scum. The scum is scraped from the scraping device to the sludge area. The clean water in the lower layer flows to the clean water tank through the collection pipe. Some of the clean water flows back for use in the dissolved gas system, while the other part is discharged.
