Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic biological filter towers, in particular to an anaerobic biological filter tower for sewage treatment. Background Art

[0002] The anaerobic biological filter tower is used to treat organic matters in sewage. The anaerobic biological filter tower is composed of a tower body, a water inlet, a water outlet, a water distributor, a three-phase separator, a lifting pipe group, a reflux pipe, an air outlet pipe, a first reaction zone and a second reaction zone. When treating sewage, the sewage enters the tower body through the water inlet and is discharged to the first reaction zone by the water distributor, so that anaerobic sludge particles react with organic matters in the sewage to generate biogas. Then, the three-phase separator at the bottom separates mud, water and biogas. Thus, the biogas and the mud-water mixture enter the gas-liquid separator through the first lifting pipe. After being separated by the gas-liquid separator, the biogas is discharged through the air outlet pipe, while the sewage returns to the bottom of the tower body again through the reflux pipe. The treated sewage enters the second reaction zone and is further degraded by anaerobic sludge particles. The generated biogas is separated by the upper three-phase separator again, so that the biogas enters the gas-liquid separator again through the second lifting pipe and is then discharged through the air outlet pipe. Finally, the treated supernatant is discharged through the water outlet.

[0003] The inventor found in daily work that when the anaerobic biological filter tower is in use, since the sewage is close to the water distributor in the first reaction zone, the sewage oscillates strongly, so that the reaction effect with anaerobic sludge particles is good. However, the sewage treated in the first reaction zone enters the second reaction zone, making it far from the water distributor, resulting in weakened sewage oscillation, and further reducing the reaction efficiency of the sewage and anaerobic sludge particles. Summary of the Utility Model

[0033] Working principle:

[0034] When treating sewage, the sewage enters the tower body 1 through the water inlet 5 and is discharged into the first reaction zone 9 by the water distributor 14, so that anaerobic sludge particles react with the organic matter in the sewage to generate biogas. Then, the sludge, water and biogas are separated by the three-phase separator 8 at the bottom layer. Thus, the biogas and the mixture of mud and water enter the gas-liquid separator 6 through the first riser 12. After being separated by the gas-liquid separator 6, the biogas is discharged through the gas outlet pipe 7, while the sewage returns to the bottom of the tower body 1 again through the reflux pipe 11. The treated sewage enters the second reaction zone 10 and is further degraded by the anaerobic sludge particles. The generated biogas is separated by the upper three-phase separator 8 again, so that the biogas enters the gas-liquid separator 6 again through the second riser 13 and is then discharged through the gas outlet pipe 7. Finally, the treated supernatant is discharged through the water outlet 4. When it is necessary to stir the wastewater and anaerobic sludge particles in the second reaction zone 10, through the driving mechanism, the first bevel gear 22 in the installation groove 21 rotates, so that the grooved rod 23 rotates, and the wave blade 25 on the moving block 24 rotates, thereby stirring and mixing the wastewater and anaerobic sludge particles, achieving the improvement of the efficiency of the wastewater and anaerobic sludge particles. Start the motor 27 to make the motor 27 rotate forward and reverse continuously, so as to drive the second bevel gear 26 to rotate, and then drive the first bevel gear 22 to rotate, and the threaded rod 28 rotates, so that the moving block 24 moves inside the inner wall of the grooved rod 23, and the wave blade 25 moves. The planetary gear 29 on the threaded rod 28 rotates on the toothed ring 210, so that the threaded rod 28 rotates. When it is necessary to sample the supernatant, the supernatant enters the circular cylinder 31 and then enters the long tube 32. The staff can use a test tube to receive the supernatant flowing out of the long tube 32 and then conduct an inspection. Pull the long rope 36 to make the piston 35 move in the installation hole 34 on the fixed plate 33 and separate from the installation hole 34, so that the supernatant flows into the long tube 32. By setting the spring 37, the piston 35 is reset.
