Detachable jet aerator and using method thereof

The invention discloses a split jet aerator, which comprises the following parts: suction inlet, water nozzle, mixing tube, dispersing pipe, tail pipe and distributor, wherein the distributor connects the tail pipe; a cone with the action of deflecting the composite liquid and reducing the local resistance is set in the pipe segment with diffusing angle of tail pipe; the CFD company adopts artificial software value to optimize the design of the structure of jet aerator, which transmits the composite liquid of effluent-living sludge into water nozzle; certain vacuum is formed in the course of jet to form three-phased composite liquid of gas, liquid and solid, which enters into the dispersing pipe to form jet distributor with certain pressure to do inclined ejection to aerate oxygen and stir. The invention improves more dynamic efficiency and more oxygen utility than traditional one, which possesses larger suction quantity, higher bubble quality, evener stirring power and more energy saving.
