When the regulating frame 4 moves to the middle of the water storage module 1, the floccules are concentrated in the middle of the device, and the valve on the floccules discharge pipe 104 is started, so that the water containing a large amount of floccules can be processed separately;

[0036] Also available in Figure 1 Aeration is performed in the state shown. Similarly, the floccules can be scraped into the interior of the screening box 3 by turning the adjusting frame 4. The water storage tank 101 can also be equipped with a spray device in the prior art to separate it from the flexible filter screen 703. The foam generated by aeration can also be removed by the adjusting frame 4 in cooperation with the external spray device. The floccules are treated separately to reduce the floccules in the water storage module 1 and reduce the pressure of the subsequent treatment process.

[0037] The flexible filter screen 703 is wound on the winding roller 702, and the flexible filter screen 703 on the winding roller 702 can be wound by the power motor 701, so that the flexible filter screen 703 that is not in contact with the sewage can be put into use.
