Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, in particular to a wastewater treatment final sedimentation tank. Background Art

[0002] The sedimentation tank after biological treatment is usually called the secondary sedimentation tank or the final sedimentation tank (final sedimentation tank). The function of the secondary sedimentation tank is to separate mud and water, clarify the mixed liquor, concentrate the sludge and return the separated sludge to the biological treatment section. The wastewater treatment final sedimentation tank is an important component of the wastewater treatment system. It is used to remove suspended matter and sediment in the wastewater. Its main function is to use the principle of gravity sedimentation to allow solid particles in the wastewater to settle to the bottom, thereby purifying the wastewater. When the wastewater is treated and precipitated, flocculants are added to the wastewater. However, at the end of the sedimentation work, if the water quality does not meet the standard, manual flocculants need to be added again, which reduces work efficiency. Therefore, a wastewater treatment final sedimentation tank is proposed.

[0003] For example, the Chinese patent with publication number CN220478210U discloses an industrial wastewater treatment final sedimentation tank that is easy to clean, which relates to the field of wastewater treatment technology, including a reaction tank and a cleaning component. A sedimentation tank is installed inside the reaction tank, and the cleaning component is arranged inside the sedimentation tank. The cleaning component includes a fixed column, a servo motor, a connecting cross bar, a limit plate, a scraper and a stirring frame. The fixed column is arranged inside the sedimentation tank, and a servo motor is installed inside the fixed column. The output end of the servo motor is connected to the connecting cross bar through a coupling, and the lower surface of the two ends of the connecting cross bar is installed with a limit plate, and the limit plate is slidably connected to the upper end of the outer wall of the sedimentation tank, and a scraper is arranged on the inner side of the limit plate.

[0004] The existing technical documents have the following problems:

[0005] The existing technical documents have some shortcomings in use. For example, during the wastewater treatment and sedimentation, flocculants are added to the wastewater. However, at the end of the sedimentation process, if the water quality does not meet the standards, flocculants need to be manually added again, which reduces work efficiency. In addition, during the wastewater sedimentation process, the water quality cannot be tested in real time, making it difficult to determine whether the water quality meets the purification standards, thereby reducing the convenience of water quality assessment. In view of this, we propose a wastewater treatment final sedimentation tank. Utility Model Content
