Sludge treatment device

The utility model discloses a sludge treatment device, which comprises at least one sewage tank, a sludge tank, a screw pump and a filter press, wherein the sludge tank is used for storing sludge and supplies the sludge to the sewage tank; the screw pump is used for pumping the sludge; the filter press is used for performing filter pressing on the sludge; one end of the screw pump is communicated with the sludge tank; and through a tee, the other end of the screw pump is respectively communicated with the filter press which is controlled to be opened/closed through a first valve and the sewage tank which is controlled to be opened/closed through a second valve. After the technical scheme is adopted, the sludge treatment device has the beneficial effects that: the screw pump is communicated with the filter press and the sewage tank through the tee; when a relatively large amount of sludge is in the sludge tank, the sludge can be compressed and filtered through the filter press; and when the sludge is required
