Theoretically, the treatment effect of the air floatation is not directly related to the retention time, but only related to the air floatation area, and if the air floatation area with the water depth H is reduced to the water depth H/10, the air floatation distance and the retention time are both reduced by 10 times, which is the well-known shallow pool theory. The inclined tube is added into the air floatation area, so that the air floatation area is increased, the Reynolds coefficient is greatly reduced, the air floatation is prevented from being carried out in a turbulent flow state, a good laminar flow state is manufactured, and the effect of shallow air floatation is achieved. Similarly, when the density of the suspended matter is more than 1, the effect of shallow pool sedimentation can be generated due to the installation of the inclined tube group, so that the sedimentation can be carried out under the turbulent flow condition. The pollutants with large grain diameter and large specific gravity and difficult to float can be concentrated in the sludge collection area, thereby achieving the purpose of water purification. The dissolved air flotation is suitable for treating water with low turbidity, high chroma, high organic matter content, low oil content, low surface active matter content or rich algae.
