Embodiment Construction
[0016] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0017] Such as figure 1 , figure 2 As shown, a jet water distributor for an anaerobic pool includes a jet tube 1 connected to the water inlet pipe, a negative pressure tube 2 that is jacketed on the jet tube 1 and is in the shape of a tapered horn, and one end is connected to the small diameter end of the negative pressure tube 2 The connected throat 3 also includes a vortex 4 connected to the other end of the throat 3, the vortex 4 is a cylindrical structure with a height greater than the outer diameter of the throat 3, and the vortex 4 is on its cylindrical surface There is a hole in the middle of the height direction and on the surface close to the outside, and the throat pipe 3 is vertically inserted into the hole and inscribed with the vortex tube 4 .
[0018] When working, the raw water to be treated or the upper circulating anaerobic liquid with a c...

The invention relates to a sewage treatment device, in particular to an anaerobic tank water distribution blending system, which includes a total water inlet, a water distribution ring tube, a water distribution branch tube and a jet-flow water distributor, wherein the jet-flow water distributor includes an injection pipe, a negative-pressure pipe which is sleeved on the injection pipe and in a reduced flared shape and a throat pipe with one end being connected with the negative-pressure pipe, and a vortex pipe which is connected with the other end of the throat pipe. The vortex pipe is of a cylindrical structure with the height being greater than the outer diameter of the throat pipe, and the vortex pipe is provided with a hole on the surface which is arranged in the middle of a cylindrical surface and close to the outer side in the height direction. The throat pipe is vertically connected into the hole and internally tangential with the vortex pipe. The jet-flow water distributor is uniformly distributed in the anaerobic tank, and the vortex pipe is vertically installed. Due to adopting the anaerobic tank jet-flow water distribution blending system, the blending of raw water and active sludge can be promoted, the anaerobic reaction efficiency is improved, and uneasiness in blockage can be achieved. The water distributors are uniformly distributed inside an anaerobic tank, so that the water inside the anaerobic tank can be uniformly blended, no dead corner exists, and the utilization rate of the device can be improved. The jet-flow water distributor and the water distribution blending system can be applied to a sewage treatment system.
Description
technical field [0001] The invention relates to sewage treatment equipment, in particular to a water distribution and stirring system for anaerobic pools. Background technique [0002] In the anaerobic reactor of the sewage treatment system, it is generally desired to fully contact and mix the raw water to be treated with the original activated granular sludge and anaerobic water in the anaerobic tank. The more uniform the mixing, the higher the water treatment efficiency and the more stable the operation. By setting a water distribution system at the bottom of the anaerobic tank, the influent water is stirred at the bottom to prevent the deposition of activated granular sludge. [0003] The water distributor forms of the existing anaerobic reactor water distribution system mainly include: [0004] Tube-hole water distribution: Evenly open fine holes on the water distribution pipe, the denser the holes, the finer the water distribution, the more uniform the water distribut...
