[0052] In this embodiment, sewage enters the flow channel 11 through the inlet 12. As the sewage flows from the inlet 12 to the outlet 13 along the length of the flow channel 11, it passes through multiple combined filter screens 2 in sequence, resulting in better filtration by filtering layer by layer.
[0053] like Figure 2 As shown, based on the above embodiment, the combined filter screen 2 is further inclined, and the upper end of the combined filter screen 2 is close to the outlet 13. That is, the combined filter screen 2 and the rear half of the bottom of the tank (the section close to the outlet 13) are set at an acute angle (e.g., 30°, 40°, 45°, or 50°). This setting can increase the contact area between the sewage and the filter screen and improve the filtration efficiency.
[0054] In the height direction of the base 1, two adjacent combined filter screens 2 can be set at different heights; the bottom of the lower combined filter screen 2 is in contact with the bottom of the tank, and its upper part is lower than the top of the flow tank 11; the bottom of the higher combined filter screen 2 is higher than the bottom of the tank, and its upper part can be flush with the top of the flow tank 11; this arrangement allows sewage to enter the next combined filter screen 2 even when the previous combined filter screen 2 is blocked.
