Description

Technical Field

[0001] The utility model relates to the technical field of environmental engineering, in particular to an aeration adjustment device for a biochemical pond. Background Art

[0002] In the field of sewage treatment, the biochemical pool is an important treatment facility that degrades and transforms organic matter in sewage through the action of microorganisms. Aeration is a key process link in the biochemical pool, which provides the required oxygen for microorganisms and promotes the biochemical reaction.

[0003] The aeration pipes of the current biochemical aeration system are arranged in parallel. No matter which layout is used in the design, local aeration unevenness will occur, and these uneven points are irregular and appear randomly. When a certain part has insufficient aeration for a long time, the bottom aeration pipe will not expand sufficiently for a long time. This abnormal situation will cause the outer diaphragm of the aeration pipe to be blocked and fatigued for a long time, so that it cannot recover, and finally form a local aeration dead zone, where sludge will accumulate. Utility Model Content

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is as follows: a biochemical pool aeration adjustment device, comprising: a biochemical pool body; a low-pressure pipe, the outer wall of the low-pressure pipe is fixedly connected to the top of the biochemical pool body through a fixing frame; a branch pipe, the outer wall of the branch pipe is fixedly connected to the inner wall of the low-pressure pipe, and the branch pipes are linearly arrayed along the central axis of the low-pressure pipe; an adjustment component, the outer wall of the adjustment component is fixedly connected to the inner wall of the branch pipe, and the adjustment component is linearly arrayed along the central axis of the branch pipe; an air guide pipe, the top of the air guide pipe is fixedly connected to the inner wall of the branch pipe, and the air guide pipe is fixedly connected to the inner wall of the branch pipe. The tubes are arranged in a linear array along the central axis of the branch pipe; the aeration pipe, the outer wall of the aeration pipe is fixedly connected to the bottom of the air guide pipe through a three-way joint, and the top of the three-way joint is fixedly connected to the bottom of the air guide pipe; the adjustment component includes a high-pressure valve, the inner wall of the high-pressure valve is fixedly connected to a high-pressure pipeline, the end of the high-pressure pipeline away from the high-pressure valve is fixedly connected to the inner wall of the branch pipe, the outer wall of the branch pipe is fixedly connected to a low-pressure valve, the outer wall of the branch pipe is fixedly connected to a support frame, the low-pressure valve and the high-pressure valve are both connected to a computer through wires, which allows the computer control system to read data through a remote pressure gauge.

[0005] Preferably, the side of the support frame away from the low-pressure pipeline is fixedly connected to the top of the biochemical pool body, the outer wall of the low-pressure pipeline is fixedly connected to the air inlet flange, and the outer wall of the air inlet flange is fixedly connected to the external low-pressure air pipe by bolts.

[0006] Preferably, the inner walls on both sides of the three-way joint are fixedly connected to the outer wall of the aeration pipe, the inner wall of the high-pressure pipe is fixedly connected to a pressure gauge, and the inner wall of the aeration pipe is fixedly connected to an aeration membrane.

[0007] Preferably, a pressure gauge, a remote-controlled electric regulating valve, a compressed air intake pipe and a regulating valve, computer software control, and a pressure gauge output pipe pressure signal are added to each branch pipe of the original ordinary biochemical pond aeration pipe. The computer comprehensively analyzes the pressure of each branch pipe, adjusts the opening and closing degree of each branch pipe valve, and automatically balances the pressure of each pipe to achieve the purpose of overall uniform aeration. If a branch pipe cannot reach the required pressure range during adjustment, the computer will determine that this branch pipe is seriously blocked and sludge is locally accumulated. After closing the low-pressure valve on this branch pipe, the high-pressure valve is opened and the branch pipe is purged with high-pressure compressed air at a pressure of 0.12Mpa. During the purge, a large amount of high-pressure gas expands the aeration membrane, purges the aeration membrane pores, and generates strong disturbance to the sludge accumulated around the aeration membrane, which is then blown away, solving the problem of the sludge accumulated around the aeration membrane posing resistance to air release.

[0008] The beneficial effects of the utility model are as follows:

[0009] 1. The utility model sets an adjustment component. On the basis of the original sewage pool aeration pipe layout, it carries out transformation on each branch pipe, remotely adjusts the air intake of each branch pipe, and uses the compressed air in the plant to force aeration and purge the branch aeration pipes with abnormalities, so as to achieve the purpose of improving the aeration balance and stability, and purging the aeration membrane and aeration dead zones.

[0016] Example:

[0017] See also Figure 1 - Figure 4 The utility model provides a technical solution: an aeration adjustment device for a biochemical pool, comprising: a biochemical pool body 1; a low-pressure pipe 2, the outer wall of the low-pressure pipe 2 is fixedly connected to the top of the biochemical pool body 1 through a fixing frame; a branch pipe 7, the outer wall of the branch pipe 7 is fixedly connected to the inner wall of the low-pressure pipe 2, and the branch pipe 7 is linearly arrayed along the central axis of the low-pressure pipe 2; an adjustment component 3, the outer wall of the adjustment component 3 is fixedly connected to the inner wall of the branch pipe 7, and the adjustment component 3 is linearly arrayed along the central axis of the branch pipe 7; an air guide pipe 4, the top of the air guide pipe 4 is fixedly connected to the inner wall of the branch pipe 7, and the air guide pipe 4 is linearly arrayed along the central axis of the branch pipe 7; an aeration pipe 5, the outer wall of the aeration pipe 5 is fixedly connected to the inner wall of the branch pipe 7, and the air guide pipe 4 is linearly arrayed along the central axis of the branch pipe 7; The outer wall is fixedly connected to the bottom of the air guide pipe 4 through a three-way joint 6, and the top of the three-way joint 6 is fixedly connected to the bottom of the air guide pipe 4; the adjustment component 3 includes a high-pressure valve 31, and the inner wall of the high-pressure valve 31 is fixedly connected to a high-pressure pipe 32. The end of the high-pressure pipe 32 away from the high-pressure valve 31 is fixedly connected to the inner wall of the branch pipe 7, and the outer wall of the branch pipe 7 is fixedly connected to a low-pressure valve 34. The opening degree of the pipeline valve is controlled by a computer program, and compressed air is used for forced aeration after closing. During the forced aeration process, the elasticity of the aeration diaphragm in the aeration pipe 5, the micropores of the aeration diaphragm, and the deposited silt can be restored to ensure uniform aeration and normal operation of each branch.

[0018] The outer wall of the branch pipe 7 is fixedly connected to a support frame 35, and the side of the support frame 35 away from the low-pressure pipe 2 is fixedly connected to the top of the biochemical pool body 1. The outer wall of the low-pressure pipe 2 is fixedly connected to an air inlet flange 8. When the pressure changes are remotely monitored or the aeration of a branch pipe 7 is visually observed to be uneven, compressed air can be turned on to perform high-pressure forced aeration and purge on a branch pipe 7. On the one hand, remote monitoring of the pipeline pressure of the aeration pipe 5 and each branch pipe 7 is realized, and the air inlet valve of the low-pressure pipe 2 is automatically opened and the air inlet valve of the high-pressure pipe 32 is closed to achieve balanced air intake in each pipeline; on the other hand, the pressure abnormality can be judged by the pressure gauge 33, and the valve opening and closing can be adjusted. When necessary, compressed air can be used to perform high-pressure forced aeration and purge on a certain pipe.

[0019] The inner walls on both sides of the tee joint 6 are fixedly connected to the outer wall of the aeration pipe 5. The inner wall of the high-pressure pipe 32 is fixedly connected to a pressure gauge 33. A device for high-pressure blowing using compressed air can restore the elasticity of the aeration membrane in the aeration pipe 5, blow out clogged aeration membrane holes, and solve the sludge accumulation problem caused by local uneven aeration.

[0020] Working principle:

[0021] When in use, first connect the low-pressure pipe 2 and the high-pressure pipe 32 to the external low-pressure air pipe and high-pressure air pipe respectively, so that there are low-pressure gas and high-pressure gas in the low-pressure pipe 2 and the high-pressure pipe 32, and the low-pressure pipe 2 needs to connect the low-pressure air pipe to the air inlet flange 8, so that the low-pressure pipe 2 and the low-pressure air pipe on the support frame 35 can be connected.

[0022] After the low-pressure air pipe and the high-pressure air pipe are connected, the aeration volume inside the biochemical pool body 1 can be adjusted by adjusting the component 3. A high-pressure valve 31 is connected to the high-pressure pipe 32 to control the amount of gas passing through the high-pressure pipe 32. A pressure gauge 33 is connected to the high-pressure pipe 32, and the air pressure in the high-pressure pipe 32 can be observed through the pressure gauge 33. A low-pressure valve 34 is connected to the branch pipe 7. Since the branch pipe 7 is connected to the low-pressure pipe 2, it is only necessary to adjust the low-pressure valve 34 to control the amount of low-pressure gas in the low-pressure pipe 2 entering the branch pipe 7.

[0023] After adjusting the two valves, the gas can enter the air guide pipe 4 on the branch pipe 7 through the branch pipe 7, and the aeration pipe 5 is connected to the air guide pipe 4 through the three-way joint 6, so the gas in the air guide pipe 4 can enter the aeration pipe 5 to aerate the inner wall of the biochemical pool body 1.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention.
