Detailed Description

For the purpose of further illustrating the various embodiments, the present utility model provides the accompanying drawings, which are a part of the disclosure of the present utility model, and which are mainly used to illustrate the embodiments and, together with the description, serve to explain the principles of the embodiments, and with reference to these descriptions, one skilled in the art will recognize other possible implementations and advantages of the present utility model, wherein elements are not drawn to scale, and like reference numerals are generally used to designate like elements.

According to an embodiment of the present utility model, a refuse transfer station is provided.

Referring to fig. 1-2 of the specification, a garbage transfer station according to an embodiment of the utility model comprises a grid water collecting tank 1, a regulating tank 2, an air floatation tank 3, a sludge tank 4, an anaerobic tank 5, an anoxic tank 6, a contact oxidation tank 7, a sedimentation tank 8 and a disinfection tank 9, wherein the left end of the grid water collecting tank 1 is connected with a water inlet 10, the contact oxidation tank 7 is provided with a fan 11, the disinfection tank 9 is connected with ozone 12, the right end of the disinfection tank 9 is connected with a water outlet pipe 13, and the water outlet pipe 13 is connected with an artificial wetland 14.

Pretreatment: because of more kitchen waste in the peripheral collected waste, the grease after the waste is squeezed is heavier and also contains the crushed waste; the unstable water quality and quantity of sewage needs to be set up and homogenized by a water collecting tank and an adjusting tank, so that the water quality and quantity entering a later biochemical unit is ensured to be stable, and the following steps are adopted: a pretreatment process of a grating oil separation tank-an adjusting tank.
