Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aerobic pool sediment treatment device for treating sewage generated after alcohol production. Background Art

[0002] SBR sewage treatment, or Sequencing Batch Reactor Activated Sludge Process, is a sewage treatment process that changes the growth environment of activated sludge in a chronological order. The process completes the basic operation processes of water intake, aeration, sedimentation, drainage and standby in a reaction tank in a chronological order.

[0003] In the alcohol production process, the aeration tank is also called an aerobic tank. The sewage is oxidized to reduce COD (chemical oxygen demand). Therefore, in order to achieve better treatment effects in the aerobic tank, a stirring function is often added. During the stirring process, solid matter containing bacteria will be stirred out and mixed into the sewage. The treated sewage can only discharge the upper clean water after sedimentation. However, due to the long sedimentation time, more aerobic tanks are required in the sewage treatment process, which occupies a larger treatment space. The aerated sewage is also stored in the sedimentation tank for sedimentation. However, the aerobic tank will need sediment containing the treated bacteria at the bottom for sewage treatment. It is necessary to transport part of the sediment in the sedimentation tank to the aerobic tank. The operation is cumbersome during implementation and inconvenient for production. Utility Model Content

[0006] Furthermore, the storage tank is arranged above the aerobic pool body, the upper part of the storage tank is cylindrical, and the outlet of the storage tank is provided with an electric valve.

[0007] Furthermore, the diameter of the storage tank is 50-200 cm, and the suction tube extends from the top to a height position of 1 / 4-1 / 3 inside the storage tank.

[0008] Furthermore, the collecting device is a truncated cone-shaped collecting bin, and a plurality of storage tanks are circumferentially arranged on the top of the collecting bin.

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] like Figure 1-3 As shown: a sewage aerobic pool sediment treatment device, including an output pipe 101 connected to the aerobic pool body, the outlet end of the output pipe 101 is connected to a plurality of vertical storage tanks 3, a delivery pump is installed on the output pipe 101, when sewage treatment is performed, the delivery pump delivers the sewage mixed liquid containing sediment to the storage tank 3 through the output pipe 101, each output pipe 101 has an independent delivery pump, which is convenient for controlling sewage sedimentation and separation, the diameter of the storage tank 3 is 50-200cm, the storage tank 3 is arranged above the aerobic pool body, the upper part of the storage tank 3 is cylindrical, the outlet of the storage tank 3 is provided with an electric valve, and the plurality of storage tanks 3 are arranged circumferentially on the top of the collection bin 301, which greatly The occupied space is reduced. The main pipe of the output pipe 101 goes deep into the middle position of the circumferentially distributed storage tank 3, and is connected to the bottom of the storage tank 3 through the branch pipe to transport the sewage mixture to the inside of the storage tank 3. Since the storage tank 3 is installed vertically and has a small diameter, the rolling sewage mixture will be stable at an extremely fast speed under the restriction of the storage tank 3, and then the sedimentation and stratification will be stable and fast. The bottom of the storage tank 3 is designed to be a closed end with a smaller diameter. The electric valve is installed on the outlet pipe. The sedimentation time of the sewage inside the storage tank 3 is controlled by the electric valve. Experiments show that each storage tank 3 can complete sedimentation and stratification after 20-30 minutes. The sedimentation speed is fast and the stratification is obvious, which greatly improves the treatment efficiency.

[0020] A suction pipe 302 is provided on the top of the storage tank 3, and the water inlet of the suction pipe 302 is plugged into the storage tank 3. The suction pipe 302 extends from the top to a height of 1 / 4-1 / 3 inside the storage tank 3. A collecting device is provided at the bottom of the storage tank 3. The clean water on the upper layer of the sewage after sedimentation is quickly pumped away through the suction pipe 302, and the electric valve at the bottom is opened. Arranging multiple groups of storage tanks 3 can pump away most of the sewage in the aerobic pool body. In the process of batch extraction, the sewage inside the aerobic pool body can be quickly replenished and re-processed. In the process of sewage replenishment, the sewage mixture extracted in the first batch has completed stratification. At this time, after the upper clean water is extracted, the electric valve at the bottom of the storage tank 3 is opened, and the sediment containing the bacteria at the bottom of the storage tank 3 will enter the collection device by its own weight. The sediment contains a certain amount of water, which does not affect the flow of the sediment, thereby ensuring the transportation effect.

[0021] The collecting device is connected with the aerobic pool body. The collecting device is a truncated cone-shaped collecting bin 301. There are multiple groups of collecting bins 301 and storage tanks 3. A conveying auger 2 is provided at the bottom of the collecting bin 301. One end of the conveying auger 2 is provided with a first outlet 201 which is connected with the storage tank 3. The other end of the conveying auger 2 is provided with a second outlet 202. A part of the sediment entering the collecting bin 301 is returned to the aerobic pool body through the conveying auger 2 through the first outlet 201 to treat the sewage in the aerobic pool body. The excess sediment is subsequently reversely started by the conveying auger 2 and discharged from the second outlet 202, and then collected and treated. In the process of sediment treatment, manual operation is greatly reduced and treatment efficiency is improved.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
