High-tech dissolved gas equipment, a micro bubble generator, is used to replace the traditional air intake equipment to dissolve gas in water, and a number of oblique pipe groups are installed in the air flotation area, including a box, a slag scraper and a rotary discharger to form a complete air flotation water purification device. Theoretically, the treatment effect of air flotation is not directly related to the residence time, but only to the air flotation area. If the air flotation area of water depth H is reduced to water depth H/10, the air floating distance and residence time will be reduced by 10 times. Dissolved air flotation is suitable for water with low turbidity, high color, high organic matter content, low oil content, low surfactant content or algae rich water. Compared with other air flotation methods, it has the advantages of high hydraulic load and compact pool body. Scope of application: papermaking wastewater, food processing wastewater, printing and dyeing wastewater, slaughter wastewater and other industrial wastewater. A dissolved air flotation machine is a machine that uses small bubbles or microbubbles to surface impurities in the medium. In order to ensure the normal operation of the equipment during use, there are also some methods during use. Let's take a look at how to use this equipment together: 1. Before turning on the power, check whether the electrical and rotating parts of the equipment are normal. 2. Do not touch electrical equipment with wet hands. If you want to check, you need to cut off the power of the air flotation machine first. 3. Keep the releaser clean frequently and strictly control the amount of coagulant added. If the treatment effect is not good, check the blockage of the releaser, the amount of coagulant, etc. in time. 4. When the pump in the dissolved air flotation machine is running, try not to stop it from running to avoid damage. 5. If you use acid and alkali, wear overalls well. Shoes, hats, masks, gloves, glasses, and other protective equipment, do not touch directly with your hands. 6. Always pay attention to the dissolved gas tank (3-4 kgf/cm2) and the dissolved gas water flow and sewage flow. Dissolved air flotation machines are designed to purify and recycle sewage and wastewater, and treat pollutants that are not easy to separate by adhering to bubbles on the water. Its sewage treatment effect is good, and the functional design is simple and easy to use. Therefore, this equipment is widely used, and according to the corresponding operation requirements, the better the purification effect.
