Problems solved by technology

[0003] At present, in the prior art, several aeration tubes are generally arranged on a single air duct, which easily causes the air supply volume of the aeration tube near the air supply port of the air duct to be different from that of the aeration tube far away from the air supply port. , and the air supply volume at the head and tail of each aeration pipe is different, which makes the aeration of the whole aeration tank uneven, and the air supply volume of each aeration pipe is also uncontrollable; To provide enough dissolved oxygen in the water, people use fan compressed air to inflate and aerate through a number of aeration tubes submerged in the water. During the maintenance period, it is impossible to provide enough soluble oxygen for the decomposing organisms in the biological sewage treatment tank in time, causing a large number of deaths of the decomposition biological products

Embodiment 1

[0019] refer to figure 1 The structural representation of the present invention shown.

[0020] The aeration device of the biological sewage treatment tank of the present invention is provided with an A air guide pipe 10a and a B air guide pipe 10b on a pair of sides of the sewage tank, and one end of the A air guide pipe 10a and B10b is connected and is provided with a common air inlet in the middle. 11. A number of aeration pipes 20 are set between the A air pipe 10a and the B air pipe 10b. The number of aeration pipes can be set according to the air pressure input by the air pipe and the size of the sewage treatment tank.

[0021] The two ends of the aeration pipe 20 are respectively connected with the A air pipe 10a and the B air pipe 10b, and the aeration pipe 20 is recessedly arranged at the bottom of the sewage treatment tank, and the aeration pipe 20 is connected with the A air pipe 10a and the B air pipe 10a through the valves 21a and 21b. B air guide pipe 10b, and t...

Embodiment 2

[0027] In this embodiment, for sewage with low turbidity, the plastic microporous aeration tube is selected as the aeration tube 20, which can not only make the aeration tube 20 durable, but also make the air bubbles released by the plastic micropores more fine and uniform. The rest of the structure and effects of embodiment 2 are the same as embodiment 1, and this embodiment will not be repeated here.

Abstract

The embodiment of the invention discloses an aerating device for a biological sewage treatment tank. The aerating device is characterized in that a gas-guide tube A and a gas-guide tube B are arranged on the edge of a sewage tank and share a gas inlet, a plurality of aerating tubes sinking into the liquid surface of the sewage tank are arranged between the gas-guide tube A and the gas-guide tube B, two ends of each aerating tube are respectively connected with the gas-guide tube A and the gas-guide tube B through valves, and a plurality of aerating micropores are formed in the surfaces of the aerating tubes. According to the aerating device, the gas-guide tube A and the gas-guide tube B are connected with the aerating tubes through the valves, and the aeration is uniform and stable and is controllable in quantity in a sewage treatment process; when the aerating tubes malfunction, the corresponding malfunctioned aerating tubes can be closed to be repaired without influencing the working of the other aerating tubes, and thus the influence caused by the repairing to a microorganism growth environment can be minimized; by virtue of bidirectional regulating valves, the aeration of each aerating tube is regulated to be uniform, the impact, caused by local overmuch or excessive-low aeration, on microorganisms in the sewage tank is avoided, and thus the influence on the sewage treatment effect is eliminated.

Description

technical field [0001] The invention relates to an aeration device, in particular to an aeration device for a biological sewage treatment tank. Background technique [0002] Aeration refers to the process of forcibly transferring the oxygen in the air to the liquid, the purpose of which is to obtain sufficient dissolved oxygen. In addition, aeration also has the purpose of preventing the suspension of the tank from sinking and strengthening the contact between the organic matter in the tank, microorganisms and dissolved oxygen. In order to ensure that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. affect the quality and efficiency of sewage treatment. [0003] At present, in the prior art, several aeration tubes are generally arranged on a single air duct, which easily causes the air supply volume of the aeration tube near the air supply port of the air duct to be different from ...
