Abstract
A sewage treatment device includes a stirring structure, a filter box, a tank filter, and a detection structure which are connected in sequence. Conveying pipelines are connected to an exterior of the stirring structure to convey sewage to an interior of the stirring structure. First water pumps are connected to the conveying pipelines to provide conveying power. An upper-layer stirrer assembly, a lower-layer stirrer assembly and a rotating shaft configured to install the upper-layer stirrer assembly and the lower-layer stirrer assembly are arranged in the interior of the stirring structure. A lifting driving cylinder drives the upper-layer stirrer assembly and the lower-layer stirrer assembly to move up and down. The upper-layer stirrer assembly includes an engaging block axially engaged with the rotating shaft and stirring blades arranged around the periphery of the engaging block at equal intervals.
