Description

Technical Field

[0001] The utility model belongs to the technical field of sewage biochemical treatment, in particular to a BBR biological rotary disc comprehensive biochemical filter tank. Background Art

[0002] Organic matter in sewage refers to organic compounds containing carbon elements that enter sewage, such as proteins, fats, carbohydrates, organic acids, etc. These organic matters usually come from domestic sewage, industrial wastewater and agricultural discharge, and they are one of the main pollutants in sewage. When treating sewage, it is necessary to remove organic matter in sewage, because excessive organic matter will consume oxygen in the water body, leading to eutrophication and ecological damage. BBR organisms are a common microorganism for sewage treatment.

[0003] When the existing BBR organisms are used to treat sewage, since the BBR organisms cannot be fully diffused in the water like chemical agents, it is inevitable that some sewage cannot come into contact with the BBR organisms. This results in the inability to completely purify local sewage and insufficient comprehensiveness of sewage treatment. At the same time, when fixed, the amount of contact between BBR organisms in different positions and sewage varies, and the growth of BBR organisms is prone to unevenness. Utility Model Content

[0004] The purpose of the utility model is to provide a BBR biological rotary disc comprehensive biochemical filter to solve the problems existing in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A BBR biological turntable integrated biochemical filter tank includes a tank body device, characterized in that: a guide device is arranged in the middle of the tank body device, and a plurality of culture devices are symmetrically arranged on the guide device; the guide device includes a guide tube, a partition plate is fixedly arranged in the middle of the guide tube, two connecting flanges are symmetrically fixedly arranged at both ends of the guide tube, a plurality of through holes are symmetrically arranged on the circumference of the guide tube, and a gear ring is arranged on the outer wall of the guide tube; the culture device includes a rotating frame, a plurality of culture media are evenly arranged on the circumference of both sides of the rotating frame, and filtering gaps are arranged between the culture media.

[0007] Furthermore: the pool body device includes a filter pool, a transmission shaft is rotatably arranged on one side of the filter pool, a gear is arranged at one end of the transmission shaft, a motor is installed at the end of the transmission shaft away from the gear, a mud discharge slope is arranged at the bottom of the filter pool, a mud discharge pipe is fixedly arranged in front of the filter pool, and a mud discharge valve is installed on the mud discharge pipe.

[0008] Furthermore: the transmission shaft is connected to the filter tank bearing, and the motor is bolted to the filter tank.

[0009] Furthermore: the guide pipe is connected to the filter tank bearing.

[0010] Furthermore: the partition plate is circular, and the partition plate and the guide tube are integrally formed.

[0011] Furthermore: the gear ring is key-connected to the guide tube.

[0012] Furthermore: the rotating frame is disc-shaped, and the rotating frame and the guide tube are welded together.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The filter tank support motor drives the transmission shaft to rotate, which drives the gear meshing ring to rotate, and drives the guide tube to rotate under the support of the filter tank, so that the BBR organisms on the culture medium rotate evenly in the circumference, making the BBR organisms grow more evenly, preventing the difference in the amount of contact between BBR organisms at different positions and sewage, and improving the reliability of BBR organism growth;

[0015] The sewage enters the guide pipe. Since the partition plate divides the guide pipe into two areas, the sewage in the guide pipe flows outward along the through hole on one side thereof, enters the rotating frame, and is finally discharged into the filter tank along the filter gap on the rotating frame. During this process, the BBR organisms on the culture medium on both sides of the filter gap absorb harmful substances in the sewage to achieve one-time sewage purification. The BBR organisms also purify the sewage in the filter tank at the same time. The sewage in the filter tank flows into the other half of the rotating frame along the filter gap on the rotating frame on the other side, and finally flows into the other half of the guide pipe through the through hole, and then is discharged along the outlet pipe. The design of sewage flowing out along one half of the rotating frame and then flowing into the other half of the rotating frame makes it easy for all sewage to flow through the culture medium twice, eliminating the possibility that some sewage does not contact with the BBR organisms, making the sewage purification more thorough and improving the comprehensiveness of the filtration.

[0027] In this embodiment, the guide device 2 includes a guide tube 201, a partition plate 202 is fixedly arranged in the middle of the guide tube 201, two connecting flanges 203 are symmetrically fixedly arranged at both ends of the guide tube 201, a plurality of through holes 204 are symmetrically arranged on the circumference of the guide tube 201, a gear ring 205 is arranged on the outer wall of the guide tube 201, the guide tube 201 is connected to the filter tank 101 bearing, the partition plate 202 is circular, the partition plate 202 and the guide tube 201 are integrally formed, the gear ring 205 is connected to the guide tube 201 with a flat key, and the two ends of the guide tube 201 are connected by the connecting flange 203. The ends are respectively connected to the water inlet pipe and the water outlet pipe, and the connection is equipped with a rotating joint to facilitate the rotation of the guide pipe 201. The sewage enters the guide pipe 201. Since the partition plate 202 divides the guide pipe 201 into two areas, the sewage in the guide pipe 201 flows outward along the through hole 204 on one side thereof. The guide pipe 201 rotates under the support of the filter tank 101, so that the BBR organisms on the culture medium 302 rotate evenly in a circle, so that the BBR organisms grow more evenly, prevent the difference in the amount of contact between the BBR organisms at different positions and the sewage, and improve the reliability of the growth of the BBR organisms;

The BBR organisms are propagated and cultured on the culture medium 302 on both sides of the rotating frame 301. When the device is in operation, the sewage enters the guide pipe 201. Since the partition plate 202 divides the guide pipe 201 into two areas, the sewage in the guide pipe 201 flows outward along the through hole 204 on one side thereof, and the outflowing sewage enters the rotating frame 301, and finally is discharged into the filter tank 101 along the filter gap 303 on the rotating frame 301. In this process, the BBR organisms on the culture medium 302 on both sides of the filter gap 303 absorb harmful substances in the sewage to achieve one-time sewage purification. At the same time, the BBR organisms also purify the sewage in the filter tank 101. The sewage in the filter tank 101 flows into the other half of the rotating frame 301 along the filter gap 303 on the other side. 1, and finally flows into the other half of the guide pipe 201 through the through hole 204, and then is discharged along the outlet pipe. The design that the sewage flows out along the half rotating frame 301 and then flows into the half rotating frame 301 facilitates all sewage to flow through the culture medium 302 twice, eliminating the possibility that some sewage does not contact with the BBR organisms, making the sewage purification more thorough and improving the comprehensiveness of the filtration. The filter tank 101 supports the motor 104 to drive the transmission shaft 102 to rotate, driving the gear 103 to engage the gear ring 205 to rotate, driving the guide pipe 201 to rotate under the support of the filter tank 101, so that the BBR organisms on the culture medium 302 rotate evenly in the circumference, making the BBR organisms grow more evenly, preventing the difference in the amount of contact between the BBR organisms and the sewage at different positions, and improving the reliability of the growth of the BBR organisms. The sludge produced by the filtration slides down the sludge discharge slope 105 to one side of the filter tank 101. When cleaning, the sludge discharge valve 107 is opened, and the sludge flows out along the sludge discharge pipe 106.
