Detailed Description

In order to describe the technical content, constructional features, achieved objects and effects of the technical solution in detail, the following description is made in connection with the specific embodiments in conjunction with the accompanying drawings.

As shown in fig. 1 and 3, the present embodiment provides a sewage pretreatment apparatus, including: the sewage treatment device comprises a box body 1 and a sewage storage tank 7, wherein a water inlet pipe group 2 is arranged on the upper portion of the box body 1, a water outlet pipe 3 is arranged at the bottom of the box body 1, a gate 4 is arranged between the box body 1 and the sewage storage tank 7, a first fine grid 5 is obliquely arranged in the box body 1, and one end, close to the water inlet pipe group 2, of the first fine grid 5 is higher than one end, close to the gate 4, of the first fine grid 5.

In the above embodiment, the end of the first fine grille 5 close to the water inlet pipe group 2 is arranged on the tank below the water inlet pipe group, and the end of the first fine grille 5 close to the gate 4 is arranged at the bottom of the gate 4. The water inlet pipe group 2 comprises at least three water inlet pipes, each water inlet pipe is provided with a first valve 21, and the water outlet pipe 3 is provided with a second valve 31. The gate 4 is provided with scales.
