0202 020202 The pretreated sewage flows into the small inflatable section equipped with a vortex aerator. During the rising process, the sewage is fully mixed with the microbubbles generated by the aerator through the inflatable section, and the aerator transfers the air on the water surface to the water through the exhaust pipe to the water. The working principle of the aerator is to use the high-speed rotation of the exhaust impeller at the bottom of the air conveyor pipe to form a vacuum zone in the water. The air on the liquid surface is fed into the water through the aerator to fill the vacuum. Microbubbles are then generated and spirally rise to the surface of the water, and the oxygen in the air dissolves into the water. 02 Due to the unbalance in density between the gas-water mixture and the liquid, a vertical buoyancy force is created that brings SS to the surface of the water. During the floating process, microbubbles adhere to the SS, and the SS relies on these bubbles to support and maintain it on the surface of the water when it reaches the surface of the water. SS floating on the surface of the water was intermittently removed by a chain scraper. The scraper moves along the entire liquid surface and pushes the SS from the inlet end of the air float to the sludge discharge pipe at the outlet end. There is a horizontal propeller in the sludge discharge pipeline that feeds the collected sludge into the collection tank. The purified sewage flows into the overflow tank and then flows to the biochemical treatment part by itself. 02 The open return pipe extends from the aeration section along the bottom of the air float. At the same time as microbubbles are generated, the vortex aeration machine forms a negative pressure zone at the bottom of the pool with a return pipe. This negative pressure action causes the wastewater to flow back from the bottom of the pool to the aeration zone, and then back to the air float section. This process ensures that around 40% of the sewage flows back and that the air flotation section can still work without water intake. 020202 02 0202 02 02 Shandong Bohui Environmental Protection Engineering Co., Ltd. is located in Zhucheng, Shandong, the hometown of dinosaurs in China.
