Description

Technical Field

[0001] The utility model relates to the field of sewage cycle anaerobic reactors, in particular to a sludge cycle anaerobic reactor for sewage treatment. Background Art

[0002] The anaerobic fluidized bed reactor is an efficient biofilm treatment method. It uses materials with large surface areas such as sand as carriers. Anaerobic microorganisms form membranes on the surface of sand or other carriers and flow in the sewage. The microorganisms come into contact with organic matter in the sewage and adsorb and decompose the organic matter, thereby achieving the purpose of treatment.

[0003] After searching, an invention patent with publication number CN101028954A specifically discloses an anaerobic reactor, including a reactor shell, a base, a water distributor, a water distributor, and a three-phase separator. The reactor shell is arranged on the base and is connected with the water distributor, the water distributor, and the three-phase separator. The reactor is cylindrical or square, divided into two parts, the lower part is the sludge expansion zone, and the upper part is the three-phase separation zone. A water distributor and a corresponding control valve are arranged between the upper end of the sludge expansion zone and the inclined plate sedimentation tank. One end of the water distributor is connected to the water inlet pump, and the other end is connected to the circulation pump. An inclined plate sedimentation tank is arranged between the water distributor and the three-phase separator. Mud discharge ports are arranged at different heights along the upper edge of the reactor shell. The advantages of the present invention include: the size of the circulating water flow rate no longer affects the separation effect of the three-phase separator on mud, water and gas, and a high organic pollutant removal rate can be obtained; its structure is relatively simple, and the manufacturing and maintenance costs are low.

[0004] During use, the existing anaerobic reactor needs to fuse the carrier of anaerobic microorganisms with sewage so that the microorganisms can adsorb organic matter in the sewage. However, during use, the existing equipment generally uses stirring to quickly fuse the two. However, since the existing equipment only simply stirs, the efficiency of fusion between sewage and the carrier is low. When there are agglomerated impurities in the sewage, the carrier and the microorganisms cannot be fully fused, thereby affecting the quality and efficiency of sewage treatment.

[0029] Furthermore, in the above structure, the stirring assembly 002 includes a connecting shaft 201, which is rotatably connected in the reaction tank 001 and axially connected to the reducer 101 at the top. A connecting disk 202 is sleeved and fixed on the connecting shaft 201, and four groups of stirring rods 203 are installed in a ring-shaped distribution on the connecting disk 202, and the stirring rods 203 are all rotatably connected.

[0030] By rotating the connecting shaft 201 , the connecting shaft 201 can drive the multiple groups of stirring rods 203 to rotate simultaneously.

[0031] Furthermore, in the above structure, a guide cylinder 204 is installed on one side of the stirring rod 203, a connecting ring 205 is installed on the inner wall of the reaction tank 001, a wavy groove 206 is opened on the inner wall of the connecting ring 205, and the wavy groove 206 is slidably connected to the guide cylinder 204, and three groups of this structure are installed in sequence on the inner wall of the reaction tank 001.

[0032] By rotating the stirring rod 203 , the guide cylinder 204 can slide along the wave-shaped groove 206 , so that the stirring rod 203 can swing up and down during the rotation process, thereby improving the stirring effect.

[0033] Furthermore, in the above structure, the crushing assembly 003 includes a through cavity 301, which is opened in the stirring rod 203, and three groups of through cavities are opened in sequence, and one group of through cavities 301 is connected with the guide tube 204, a connecting cavity 302 is opened between the three groups of through cavities 301, and an annular cavity 303 is opened on the inner wall of the through cavity 301, a connecting rod 304 is connected through the through cavity 301 and the connecting cavity 302, and the connecting rod 304 is sleeved with the guide tube 204.

[0034] The connecting cavities 302 can make each group of through cavities 301 communicate with each other, so that the connecting rods 304 can slide in each group of connecting cavities 302 and the through cavities 301 .

[0035] Furthermore, in the above structure, a push ring 305 is sleeved and fixed on the connecting rod 304, and the push ring 305 is slidably connected to the connecting cavity 302.

[0039] How this utility works:

[0040] Refer to the instruction manual Figure 1-5 ,

[0041] After the sewage is added into the reaction tank 001, the stirring rod 203 is driven to rotate through the connecting shaft 201, and because the guide cylinder 204 can move along the wavy groove 206, the stirring rod 203 can swing up and down, so that the microbial carrier and the organic matter in the sewage can be fully integrated. At the same time, due to the continuous movement of the stirring rod 203, one side of the stirring rod 203 contacts the wavy teeth 309. When encountering a protrusion, the stirring rod 203 will move to one side, and in the subsequent movement process, under the action of the spring 306, the stirring rod 203 is reset, so that the stirring rod 203 makes the fins 307 reciprocate during the rotation process, so that the lumps in the sewage are fully broken up, so that the sewage can be fully integrated with the microorganisms, thereby achieving the improvement of the efficiency and quality of the fusion of the carrier and sewage in the equipment.
