Modified polyurethane filter screen integrated equipment for sewage treatment

The invention belongs to biodegradable sewage treatment equipment, which is formed by modified polyurethane filter screen large holes (1), middle holes (2), small holes (3), a sewage inlet (4), a clear water outlet (5), large contaminants (6), separation filter cloth (7), cabin separation plates (8), middle contaminants (9) and small contaminants (10), which are as shown in an abstract figure. The equipment can realize sewage treatment for various sewage through arranging a corresponding filter screen. In the first case, the sewage treatment equipment is internally provided with multiple groups of modified polyurethane filter screens with different specifications, and the modified polyurethane filter screens corresponding to contaminants are arranged according to the sewage contaminants so as to degrade and clear the contaminants. In the second case, the sewage treatment equipment is provided with the modified polyurethane filter screens with different specifications so as to degrade and separate the contamin
