Description
Technical Field
[0001] The utility model belongs to the field of sewage treatment, and particularly relates to a sedimentation device for sewage treatment. Background Art
[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. In the process of sewage treatment, it is usually necessary to use a sedimentation device to precipitate the sewage, but sewage contains a large amount of fixed impurities, and solid impurity precipitation is required in sewage treatment.
[0003] When treating sewage, it is necessary to first precipitate the wastewater. However, when the sewage is precipitated, the filter screen inside the sedimentation tank is easily clogged due to the accumulation of solid matter when the sewage is precipitated for too long. Moreover, the existing filter screen is mostly fixed in the sedimentation tank, which makes it difficult to clean and replace the filter screen, reducing the use of the device. At the same time, after the sludge particles at the bottom of the existing sedimentation tank are precipitated to the slope surface, when extracting the precipitated sewage inside the sedimentation tank, a small amount of sludge in the tank is easily extracted from the pumping pipe, thereby reducing the use effect of the device and reducing the practicality of the device.
