Description

Technical Field

[0001] The utility model relates to the field of sewage treatment sedimentation tanks, in particular to a sedimentation tank used for sewage treatment. Background Art

[0002] With the development of my country's economy, the process of urbanization and industrialization in my country has developed rapidly, and the problem of water pollution has become increasingly prominent. As an environmental improvement project, the urban environmental sewage treatment project has a very positive significance for the protection of urban water environment, the utilization of water resources, and the improvement of residents' living environment. The rapid development of my country's national economy has increased the pressure and burden on the urban environment. It is a process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily life of ordinary people. There are usually various particles and suspended devices in sewage. The existing treatment method is the static method, that is, sedimentation in a sedimentation tank. The sedimentation tank is a building that uses sedimentation to remove suspended matter in water. It is a water purification equipment that uses the natural sedimentation or coagulation of water to remove suspended matter in water. The sedimentation tank mainly performs physical precipitation of large particles and accumulation of some suspended matter and oxidation reaction of organic matter on sewage, etc., in preparation for subsequent purification treatment.

[0003] In the sedimentation tanks currently used, sewage and sedimentation agents are not mixed sufficiently and evenly. In order to ensure that the quality of sewage treatment is not reduced, it takes longer time for sewage impurities to settle. The stirring device installed in the existing sedimentation tank is fixed in position and has a small stirring area. It cannot act on a large area in the sewage tank and cannot effectively improve the agent mixing efficiency. At the same time, there will still be flocculent impurities suspended in the sewage after the agent is mixed, and effective precipitation cannot be carried out, which affects the effect of sewage sedimentation treatment and causes inconvenience in subsequent purification operations.
