Sewage treatment device with adjustable water outlet weir

The utility model relates to a sewage treatment device with an adjustable effluent weir. The sewage treatment device comprises a barrel body, an inner conical barrel, a wall plate, the effluent weir and a pipeline, the wall plates divide the area between the cylinder body and the inner conical cylinder into a plurality of process units; the pipeline is a sewage inlet and outlet passage and is used for communicating each process unit with the inner conical cylinder; the effluent weir is mounted at the upper part in the inner conical barrel through a screw, the height of the effluent weir is adjusted by rotating threads, sewage is subjected to solid-liquid separation in the inner conical barrel, and a separated liquid phase leaves the inner conical barrel through the effluent weir. By adjusting the height of the effluent weir, the technical problem that in the prior art, the sewage treatment device is difficult to realize absolute level due to installation errors, so that the effluent efficiency of the device i
