The invention discloses a method and device for carrying out surface blowdown, blue-green alga treatment and oxygenation simultaneously. A drainage pipe is vertically arranged at the blowdown position in the center of a pond, a perforated blowdown pipe which is transversely connected to an elbow at the upper end of the drainage pipe and rotates around the center drainage pipe is used for carrying out surface blowdown and discharging blue-green algae at the same time, and a rotary aerator connected to the tail end of the blowdown pipe carries out oxygenation at the same time. Due to the fact that the drainage vertical pipe is fixed to the center of the pond, holes are formed in the transverse pipe, and one half of the drainage vertical pipe is immersed in surface-layer water, after the outer blowdown pipe is pulled out, only water on the surface flows in through the pipe holes; due to the fact that the transverse pipe rotates, all surface dirt is sucked into the pipe to be discharged. Due to the fact the blue-green algae generally exist on the surface layer of the water, the blue-green algae are sucked and discharged while the surface dirt is sucked and discharged, and the blue-green algae are treated. Due to the fact that the aerator is unfixed, the blue-green algae are started to push the pipe to rotate around the center pipe along the water surface, and the rotary aerator and the driven pipe can stir the surface water to achieve the aim of oxygenation.

Method and device for carrying out surface blowdown, blue-green alga treatment and oxygenation simultaneously

The utility model discloses a breed aquatics pond surface blowdown and device of administering blue alga oxygenation simultaneously. Taking to set up the drain pipe perpendicularly in blowdown department of pond central authorities and inserting the outlet, the drain pipe upper end is through 90 degrees return bends of bearing connection, and the return bend is one section one -way trompil blow off pipe of transverse connection again, passes through an articulate table flotation in the oxygen -increasing machine of the surface of water at the end of blow off pipe. The utility model discloses owing to be fixed with a riser and waterproof in pond central authorities, violently the pipe is upward porose, and half submergence is in the top layer aquatic, so behind the blow off pipe outside extracting, only surperficial water passes through the tube hole and flows out, in addition violently manages and is rotating, just all discharges the filth on surface in the suction pipe. And because the blue alga is generally concentrated on the top layer of water, the utility model discloses discharge top layer water that can be single -minded, the blue alga is administered to the blue alga of just can discharging simultaneously. Because the oxygen -increasing machine is unset, start the oxygen -increasing machine and promote tub rotatoryly around the central canal along the surface of water promptly, rotatory oxygen -increasing machine and the surperficial water of the pipe of drive stirring just can reach the purpose of oxygenation.
