Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a reoxygenation biological generator system device. Background Art

[0002] In the prior art, a fixed bed biofilm filter is an anaerobic filter for treating domestic sewage and organic sewage. Its basic structural feature is that a fixed partition is provided in the middle of the anaerobic biological reaction to divide the reactor into two spaces, upper and lower. A filter material layer composed of crushed stone is provided above the partition. In order to enhance the filtering effect, a filter plate with holes is provided between the filter materials on the upper side of the partition plate in the vertical direction. This is prone to short-circuiting of the filtrate and clogging of the filter. In addition, the anaerobic treatment consumes the dissolved oxygen in the water, thus affecting the sewage treatment effect and the discharged water quality. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] The utility model provides a reoxygenation biological generator system device, such as Figure 1-2As shown, it includes a sedimentation tank 1, an opening is provided on the side of the sedimentation tank 1, grooves are provided on the outer walls at both ends of the opening, a blocking door 2 is provided at the opening, and limit blocks are fixedly installed on the outer walls at both ends of the blocking door 2, the limit blocks are slidably installed inside the groove, and the blocking door 2 is slidably installed at the opening of the sedimentation tank 1 through the limit blocks, and the outside of the sedimentation tank 1 is connected to a generating device capable of reoxygenation.

[0020] First, the sewage is poured into the sedimentation tank 1 to allow the impurities that can be precipitated in the sewage to precipitate. The remaining water enters the storage tank 4 through the connecting pipe 3 for the lower process. After the work is completed, the blocking door 2 is slid upward to expose the opening to facilitate cleaning of the impurities inside the sedimentation tank 1.

[0021] like Figure 3-5 As shown, the generating device includes a storage tank 4, a connecting pipe 3 is fixedly installed on the outer wall of the storage tank 4, and the end of the connecting pipe 3 is fixedly installed on the sedimentation tank 1, a buffer pipe 5 is fixedly installed on the bottom end of the storage tank 4, and the buffer pipe 5 is set to be U-shaped, and an anaerobic tank 6 is fixedly installed on the end of the buffer pipe 5, a filter screen 7 is fixedly installed inside the anaerobic tank 6, and a suspended filter material layer 8 is placed on the top of the filter screen 7, a guide pipe 10 is fixedly installed on the outer wall of the top of the anaerobic tank 6, a reoxygenation tank 9 is fixedly installed on the side of the anaerobic tank 6, and the end of the guide pipe 10 is fixedly installed on the reoxygenation tank 9, a partition 11 is fixedly installed on the inner wall of the bottom end of the reoxygenation tank 9, and a plurality of partitions 11 are provided, and fillers are placed between two adjacent partitions 11, a drainage tank 12 is fixedly installed on the side of the reoxygenation tank 9, and a drainage pipe 13 is fixedly installed on the bottom end of the drainage tank 12.

[0022] When the precipitated water enters the storage tank 4, the water can be buffered to prevent the water flow rate from being too fast and causing impurities to enter the buffer tube 5. At the same time, a stainless steel filter is fixedly installed inside the buffer tube 5 to prevent impurities from entering the buffer tube 5. At the same time, the buffer tube 5 and the storage tank 4 are interconnected, allowing the water to slowly enter the anaerobic tank 6, so that the water can exist in the anaerobic tank 6 for a longer time. The water quality will slowly rise and fall in the anaerobic tank 6. When rising, the water can pass through the filter screen 7 and the suspended filter material layer 8 to filter and purify the water quality. At the same time, because the suspended filter material layer 8 is in a suspended granular state, the liquid flow can penetrate up and down and left and right through the filter bed and the filter material layer, and the filtration is sufficient. The sludge is easy to sink, which overcomes the blockage and short-flow phenomena of the filter material. There is no need to replace and backwash the filter material. The purified water enters the reoxygenation tank 9 through the guide pipe 10, is blocked by the partition 11, and will collide with the partition 11. During the collision, the outside air can be dissolved into the water, and the flow rate of the water can be slowed down, increasing the time inside the reoxygenation tank 9. The fillings between the partitions 11 are pebbles, brown hair and activated silt, which can easily hang on the biological film. At the same time, the surface of the partition 11 is rough, which can also hang on the biological film, allowing the water to fully contact the biological film, so as to increase the dissolved oxygen content in the water. The treated water enters the drainage tank 12 and is discharged from the drainage pipe 13.

[0023] Working principle: First, the sewage is poured into the sedimentation tank 1 to allow the impurities that can be precipitated in the sewage to precipitate. The remaining water enters the storage tank 4 through the connecting pipe 3 for the lower process. When the precipitated water enters the storage tank 4, the water can be buffered to prevent the water flow rate from being too fast and causing impurities to enter the buffer tube 5. At the same time, a stainless steel filter is fixedly installed inside the buffer tube 5 to prevent impurities from entering the buffer tube 5. At the same time, the buffer tube 5 and the storage tank 4 are interconnected, allowing the water to slowly enter the anaerobic tank 6, so that the water can exist in the anaerobic tank 6. The time can be increased, and the water quality will slowly rise and fall in the anaerobic tank 6. When rising, the water can pass through the filter screen 7 and the suspended filter material layer 8 to filter and purify the water quality. At the same time, since the suspended filter material layer 8 is in a suspended granular state, the liquid flow can pass through the filter bed and the filter material The layers penetrate up and down and left and right, the filtration is sufficient and unobstructed, the sludge is easy to sink, the blockage and short-flow phenomenon of the filter material is overcome, and the filter material does not need to be replaced and backwashed. The purified water enters the interior of the reoxygenation tank 9 through the guide pipe 10, is blocked by the partition 11, and will collide with the partition 11. During the collision, the outside air can be dissolved into the water, and the flow rate of the water can be slowed down, increasing the time inside the reoxygenation tank 9. The fillings between the partitions 11 are pebbles, brown hair and active sludge, which can easily hang on the biological film. At the same time, the surface of the partition 11 is rough, which can also hang on the biological film, so that the water can fully contact the biological film, so as to increase the dissolved oxygen content in the water. The treated water enters the drainage pool 12 and is discharged from the drainage pipe 13. After the work is completed, the blocking door 2 is slid upward to expose the opening, which is convenient for cleaning the impurities inside the sedimentation tank 1.

[0024] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
