[0020] In order to further explain the technical scheme of the utility model, the following is elaborated in detail through specific embodiments.

[0021] Please refer toFigures 1-5 The utility model provides a kind of biological chemical wastewater pretreatment equipment, including sewage pretreatment device 1, sewage pretreatment device 1 includes three-way pipe 11, replacement pipe 12, water inlet 13, drain pipe 14, limit ring 15, pipe cover 16, connecting rod 17, screen cylinder 18, screen hole 19 and cylinder mouth cover 110, three-way pipe 11 top is equipped with replacement pipe 12, three-way pipe 11 side is equipped with water inlet 13, three-way pipe 11 bottom is equipped with drain pipe 14, three-way pipe 11 inner wall is welded with limit ring 15, limit ring 15 is below water inlet 13, replacement pipe 12 external thread is screwed with pipe cover 16, pipe cover 16 bottom surface middle screw is equipped with connecting rod 17, connecting rod 17 bottom end is connected with screen cylinder 18 inner bottom surface middle screw, screen cylinder 18 is placed in three-way pipe 11 inside from replacement pipe 12 and passes through limit ring 15 inside, screen cylinder 18 outer surface and bottom surface are all through screen hole 19, screen cylinder 18 top end cylinder mouth part is sleeved with cylinder mouth cover 110, cylinder mouth cover 110 and three-way pipe 11 inside slide sleeve, and the outer diameter of cylinder mouth cover 110 is greater than the inner diameter of limit ring 15, so that limit ring 15 can stop cylinder mouth cover 110 to limit screen cylinder 18 in predetermined installation position.

[0022] Further explanation, the maximum length of connecting rod 17 is not more than 1.2m, avoid that connecting rod 17 is too long and affects stability.

[0023] Further explanation, the length of screen cylinder 18 is not less than 30cm, so that screen cylinder 18 has enough filtering area, and it is not easy to cause blocking phenomenon.

[0024] Further explanation, the outer diameter of screen cylinder 18 is not more than 80% of the inner diameter of three-way pipe 11, to reserve enough surface flow space for screen cylinder 18.
