[0021] Referring to Figures 1-2 The utility model provides a kind of water distribution and air distribution integrated system applied to wastewater treatment, including: support frame, water distribution pipe 1 and aerator 2, wherein:

[0022] The support frame comprises at least one water inlet pipe 3, and the water inlet pipe 3 is provided with a pipe joint for connecting a pipeline. The water distribution pipe 1 is provided with a water distribution hole 4, and the water distribution pipe 1 is installed on the support frame and communicates with the water inlet pipe 3, so that the water distribution pipe 1 and the support frame form an integral whole. The aerator 2 is located inside the water distribution pipe 1, and the air inlet end of the aerator 2 is provided with a pipe joint 5, and the pipe joint 5 is located outside the water distribution pipe 1 and is installed on the support frame, so that the aerator 2 and the support frame are fixed together, and the connection of the aeration pipeline is not affected.

[0023] In use, the integrated system is directly placed at the bottom of the sewage treatment tank, and then the sewage conveying pipeline is connected through the pipe joint, and the aeration pipeline is connected through the pipe joint 5, which greatly reduces the installation workload of the equipment and reduces the maintenance difficulty of the aeration pipeline in the later operation. In addition, since the aerator 2 is directly arranged in the water distribution pipe 1, the air distribution pipeline is combined with the water distribution pipe 1, which simplifies the structure, reduces the step of separately arranging the air distribution pipeline, and at the same time, effectively reduces the aeration wind pressure under the condition of ensuring the aeration amount, reduces the impact of the aeration airflow on the filler, and reduces the abrasion of the filler caused by aeration scrubbing. In addition, the water flow in the water distribution pipe 1 can also be used to reduce the blocking probability of the aeration membrane in the aerator 2.

[0024] In the embodiment, the number of water inlet pipes 3 in the support frame is two, and the two water inlet pipes 3 are oppositely arranged. The water distribution pipe 1 is located between the two water inlet pipes 3, and the water distribution pipe 1 is provided with a plurality of water distribution pipes 1, and each water distribution pipe 1 is arranged at intervals along the length direction of the water inlet pipe 3, and the two ends of each water distribution pipe 1 are fixedly connected with the two water inlet pipes 3 and communicate with each other. In use, the two water inlet pipes 3 can respectively convey water to the inside of the water distribution pipe 1 from the two ends of the water distribution pipe 1, which can not only ensure the water conveying amount, but also make the pipe diameter of the water distribution pipe 1 smaller.

[0025] Further, in order to further increase the support strength of the support frame, the support frame in the embodiment further comprises a connecting rod 6 connecting the two water inlet pipes 3 to form an integral whole, and the connecting rod 6 is provided with at least two connecting rods 6, and at least two connecting rods 6 are arranged at the two ends of the two water inlet pipes 3.

[0026] In addition, the water distribution hole 4 in the embodiment is arranged on the upper surface of the water distribution pipe 1, so as to avoid the accumulation of gas generated by aeration in the water distribution pipe 1 and the formation of an air cavity in the water distribution pipe 1, thereby avoiding the reduction of the water passing area of the water distribution pipe 1 due to the formation of the air cavity.

[0027] Further, the water distribution hole 4 comprises a first water outlet, a second water outlet, and a communication channel connecting the first water outlet and the second water outlet, the first water outlet and the second water outlet are located on the upper surface of the water distribution pipe 1 and are separated on both sides of the center line of the water distribution pipe 1, and the communication channel is located between the first water outlet and the second water outlet. The two water outlets and the communication channel connecting the two water outlets can effectively ensure that the air has enough caliber to discharge the water distribution pipe 1.

[0028] In the embodiment, the water distribution pipe 1 adopts a square tube to ensure that the top surface has sufficient area to design the water distribution hole 4 to prevent the formation of an air cavity in the pipe.

When the aerator 2 is blocked or damaged, or the aerator pipeline is blocked or damaged, etc., the aerator pipeline can be directly separated from the pipe joint 5 for maintenance; then the pipe joint 5 is separated from the installation part in the aerobic tank, and then the aerator 2 is directly pulled out of the water distribution pipe 1.

[0030] In addition, in addition to the tubular aerator, the aerator 2 can also adopt a single-hole membrane aerator or a hose aerator and other types of aerators 2.

[0031] In summary, the utility model compared with prior art has at least the following advantages:

[0032] 1. The integrated modular design greatly reduces the workload in the later period and reduces the maintenance difficulty of the aerator pipeline in the later operation process.

[0033] 2. The aerator 2 is directly arranged in the water distribution pipe 1 to combine the air distribution pipeline with the water distribution pipe 1, which simplifies the structure, reduces the air distribution pipeline alone, at the same time, reduces the abrasion of the aerator 2 to the filler and the blocking probability of the aerator membrane.

[0034] 3. By designing the position and structure of the water distribution hole 4, the smoothness of gas discharge can be effectively guaranteed, and the gas cavity formed in the air distribution pipe due to the accumulation of the gas generated by aeration in the water distribution pipe 1 can be avoided.
