[0002] The oxidation ditch process is a variation of the activated sludge process. The oxidation ditch is generally composed of a ditch body, aeration equipment, water inlet and outlet devices, diversion and mixing equipment. The aeration equipment has a key impact on the treatment efficiency, energy consumption and treatment stability of the oxidation ditch.

[0003] In the prior art, in most cases, when using an aeration system, there are one or two aeration pipes, which are symmetrically arranged to complete the aeration of the water source; however, due to the small number of aeration pipes, less aeration flows out from the inside of the aeration pipes, which reduces aeration, fails to improve the efficiency of oxidation, fails to promote the decomposition and metabolism of pollutants, reduces the dissolved oxygen content in the water, the number of bacteria and microorganisms in the water body, reduces its self-purification ability, and is inconvenient to use. In view of this, we have introduced a liftable aeration system for oxidation ditches. Utility Model Content

The connecting pipe A12 is connected to the bottom of the air inlet pipe 6 at equal intervals. The surface of the connecting pipe A12 is connected to a flange A13, the bottom of the flange A13 is connected to a collar 14, the bottom of the collar 14 is connected to a flange B15, the bottom of the flange B15 is connected to the top of the connecting pipe B16, the bottom of the connecting pipe B16 is connected to a square head 17, and the aeration pipe 20 is connected to the surface of the square head 17.

The interior of the square head 17 is provided with an internal thread. The external thread on the surface of the joint 19 is matched and screwed with the internal thread inside the square head 17. A sealing ring 18 is connected between the joint 19 and the square head 17. The setting of the sealing ring 18 can seal the gas to prevent the gas from flowing out from the gap between the joint 19 and the square head 17, thereby increasing the sealing performance.

[0027] The other end of the aeration pipe 20 is connected to a tail end joint 21 , and the tail end joint 21 can be provided to seal the tail end of the aeration pipe 20 .

[0028] A valve 5 is connected to one side of the air intake pipe 6 , and an air intake port 4 is connected to one side of the valve 5 . When the valve 5 is opened, the gas inside the air intake port 4 can enter the interior of the air intake pipe 6 .
