Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment, and specifically relates to a sedimentation tank for sewage treatment. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water and is a device for purifying water. Suspended matter in water is removed by natural sedimentation or coagulation sedimentation of water. Some sedimentation tanks use an isolation plate in the middle of the sedimentation tank, and an overflow port is set on the top of the isolation plate. Impurities in the water will fall to the bottom of the sedimentation tank through natural sedimentation, and the water will flow to the downstream through the overflow port. In order to prevent suspended matter from flowing to the downstream, a filter screen is usually installed at the overflow port. At present, the filter screen is usually installed at the overflow port by plug-in. When cleaning and maintenance are required in the later stage, the filter screen needs to be removed manually. After the filter screen has been used for a period of time, the resistance to removal is relatively large. When the filter screen is removed manually, it takes a lot of manpower, which makes it inconvenient to maintain and clean the filter screen on site. Utility Model Content
