Side bottom with wet part 1 and protruding.Length (perpendicular to the longitudinal direction of paper in Fig. 1) with wet part 1 be 1.0~
2.0m, top width (transverse direction parallel with paper in Fig. 1) are 0.3~0.6m, are highly 0.3~0.5m；In guiding region 14
The angle of deflector is set as 30 °~45 °, and the width of guiding region 14 is 0.2m smaller than the width with 1 top of wet part, and described leads
" duck-beak type " flow-guiding mouth is formed between flowing plate and water conservancy diversion splash-back b.
In another embodiment of the present invention program, as shown in figure 5, the section configuration with wet part 1 can also be trapezoidal
Shape, the side with wet part 1 form parallel flow-guiding mouth as water conservancy diversion splash-back b between water conservancy diversion splash-back b and deflector.
In order to guarantee that sewage uniformly flows into first order screening component 21 along the deflector, overcurrent mouth a is arranged in institute
State the surface of deflector.
In one embodiment of present disclosure, the underface of second level screening component 22 is arranged in water drainage part 4.Row
Wet part 4 may include interim water area 41 and discharge outlet 42；Water drainage part 4 is flowed by the sewage of second level screening component 22
Interim water area 41, then by be located at interim 41 bottom of water area discharge outlet 42 be discharged the purification device.
When it is implemented, the length (perpendicular to the longitudinal direction of paper in Fig. 1) of water drainage part 4 is 1.0~2.0m, width (Fig. 1
In the transverse direction parallel with facing directly) be 0.3~0.6m, be highly 0.3~0.6m.
Specifically, the length of purifying part 2 should be big to prevent the outside for flowing into purifying part 2 with the sewage in wet part 1
In or equal to the length with wet part 1；In order to prevent first order screening component 21 retain float object be slipped to float object collection
The outside of component 3, the length for floating object collecting part 3 should be greater than or equal to purifying part 2 length；Similarly, in order to guarantee to pass through
The sewage for crossing second level screening component 22 effectively flows into interim water area 41, and the length of water drainage part 4 should be greater than or be equal to the
The length of second level screening component 22, the width of water drainage part 4 are equal to the width of second level screening component 22.
