Device for filtering sludge from sewage and tobacco production sewage treatment system

The invention relates to a device for filtering sludge from sewage and a tobacco production sewage treatment system. The device for filtering sludge from sewage comprises: a tank body (6); a cylindrical filtering component (8) rotatably arranged in the tank body (6) and provided with an inlet for introducing to-be-filtered sewage and a water outlet hole formed in the peripheral surface; and a driving component (9) in transmission connection with the cylindrical filtering component (8) so as to drive the cylindrical filtering component (8) to rotate. According to the invention, after to-be-filtered sewage enters the rotating cylindrical filtering component (8), sludge and sewage are separated under the action of centrifugal force, and the separated sewage enters the space between the cylindrical filtering component (8) and the tank body (6) and then is discharged out of the tank body, so that the problems that in the prior art, due to the fact that filter cloth and a filter plate are adopted, the structure is
