Description

Technical Field

[0001] The present application relates to the technical field of anaerobic tanks, and specifically to an anaerobic tank for sewage treatment. Background Art

[0002] Sewage treatment equipment generally includes sedimentation tanks, regulating tanks, biochemical tanks, secondary sedimentation tanks and disinfection tanks. Biochemical tanks generally include anaerobic tanks and aquaculture tanks. Anaerobic tanks are mainly used for anaerobic digestion. For sewage with high COD concentration in the influent, anaerobic reaction is usually carried out first to improve the COD removal rate, convert high-molecular-weight, difficult-to-degrade organic matter into low-molecular-weight, easily degradable organic matter, and improve the BOD / COD ratio.

[0003] Under anaerobic conditions, some difficult-to-degrade organic matter, such as macromolecular organic matter, can be hydrolyzed into small molecular organic matter by the extracellular enzymes secreted by anaerobic bacteria, which is conducive to the operation of the subsequent aerobic biochemical pool. Otherwise, it will have an impact on the aerobic pool, resulting in the effluent COD not meeting the standard. Anaerobic bacteria are a type of bacteria that grow better under anaerobic conditions than in an aerobic environment, and cannot grow on the surface of solid culture medium under air (18% oxygen) and (or) 10% carbon dioxide concentration.

[0004] In the prior art, the anaerobic tanks of sewage treatment plants are generally open-air, and sewage is allowed to stand in the anaerobic tanks to react with anaerobic bacteria. However, since the anaerobic tanks are open-air, anaerobic bacteria that are closer to the air are prone to die or have reduced activity due to the high oxygen concentration at this location. Therefore, an anaerobic tank for sewage treatment is needed to solve the above problem. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present application provides an anaerobic tank for sewage treatment that can seal the anaerobic tank and improve the activity of anaerobic bacteria.

[0009] By adopting the above technical solution, when sewage is treated through the anaerobic tank body, the first motor is started to drive the reel to rotate and release the sealing cloth, and at the same time, the anaerobic tank body is covered by pulling one end of the sealing cloth. The covering of the sealing cloth can reduce the sewage from contacting more oxygen. When the sealing cloth covers the anaerobic tank body, two sets of multi-stage cylinders are started at the same time to drive the connecting plate and the pressure frame to descend, and the sealing cloth is pressed by the pressure frame, so that the sealing cloth is tightly attached to the anaerobic tank body, thereby improving the sealing performance. Therefore, an anaerobic tank for sewage treatment is provided, which can seal the anaerobic tank and improve the activity of anaerobic bacteria.

[0011] By adopting the above technical solution, the spool is driven to rotate by rotating the rotating shaft, and the connecting rope is wound up at the same time, and the sealing cloth is pulled by the connecting rope to move on the anaerobic tank body.

[0012] Preferably, a second motor is disposed on the second fixing plate, and an output end of the second motor is connected to the rotating shaft.

[0018] When sewage is treated through the anaerobic tank body, the first motor is started to drive the reel to rotate and release the sealing cloth, and at the same time, the anaerobic tank body is covered by pulling one end of the sealing cloth. The covering of the sealing cloth can reduce the sewage from contacting more oxygen. When the sealing cloth covers the anaerobic tank body, two sets of multi-stage cylinders are started at the same time to drive the connecting plate and the pressure frame to descend, and the sealing cloth is pressed by the pressure frame, so that the sealing cloth is tightly attached to the anaerobic tank body to improve the sealing performance.
