Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a hanging aeration device which is easy to maintain. Background Art

[0002] The aeration unit pools of existing sewage treatment plants use underwater pipe aeration technology. During the operation of the aeration pools, the suspended matter in the water and the residues produced by the consumption of biological flora accumulate at the aeration holes of the aeration pipes, causing the micropores of the aeration pipes at the bottom of the unit pools to be blocked. The aeration holes cannot be aerated normally during aeration, and the process requirements cannot be met. At the same time, due to the low safety and reliability of underwater pipe laying, the overall complexity, the economy and timeliness are relatively low. The use of suspended aeration can solve the above problems to a certain extent, but the suspended aeration device also has the disadvantage of relatively weak fixing points during installation, which cannot fix and support the plastic aeration pipes and is inconvenient to use.

The two sides of the support pipe 2 are connected to the sewage treatment tank 1 through mounting components 4 respectively. The support pipe 2 is provided with an aeration component 3. The aeration component 3 includes a plurality of main pipes 303. The main pipes 303 are connected to branch pipes 304 through three-way joints 301. The branch pipes 304 are deep in the sewage treatment tank 1. The project mainly uses PPR pipes to transform the underwater pipe aeration process into suspended aeration on water. Three-way suspended aeration pipes are arranged. The front-to-back and left-to-right spacing of each pipe is about 50 cm. The main air inlet valve and branch valve are installed. The bottom of the branch pipe 304 is provided with an aeration port, and its height is consistent with the original underwater pipe aeration port (30 cm above the bottom of the pool). The aeration volume is controlled by the aeration branch valve. By using a suspended aeration device for aeration, the aeration volume in the unit pool is significantly increased, and the dissolved oxygen content in the pool is maintained at above 1.5mg / L. The aeration pool meets the requirements of aerobic operation, ensuring that the sewage is treated up to standard. At the same time, the oxygenation efficiency and power efficiency of the suspended aeration equipment are significantly improved, and the dissolved oxygen in the sewage in the unit pool can be adjusted from the original 1.5mg / L to above 5.0mg / L. The on-site maintenance is simple, and the aeration device can be inspected and maintained without affecting normal operation (without stopping water and air supply). The on-site operation is practical and reliable.

[0032] During aeration, gas is input into the aeration tank through the main pipe 303 and the branch pipe 304 located in the middle position, so that the dissolved oxygen concentration is distributed in a wave-like manner, and the aeration volume is controlled by adjusting the opening of the main air inlet valve and the valve 305 in time according to the dissolved oxygen content in the aeration tank, thereby effectively controlling the dissolved oxygen concentration in the aeration tank to meet the requirements of the sewage treatment process.
