[0002] A breeding farm refers to a farm that raises pigs, dairy cows, laying hens, and broilers and has legal person status and is approved by local agricultural, industrial and commercial administrative departments. As people's living standards improve, the number of breeding farms is also increasing year by year. Waste and wastewater are often generated in breeding farms, which need to be treated in a timely manner to avoid affecting the environment. The current treatment methods are generally sedimentation, disinfection, filtration, etc. The first step is to precipitate the waste, followed by solid-liquid separation.

[0003] The current sedimentation tank design is relatively simple, and only realizes the basic sedimentation treatment of waste and wastewater. When the sludge needs to be salvaged, it will cause fluctuations in the water body, and the fluctuations will affect the sludge, and then affect the sedimentation of the waste and the salvage of the sludge. It is impossible to achieve automatic and stable salvage of the sludge. At the same time, due to the shape of the sedimentation tank, it is easy to cause incomplete salvage effect; and the sludge still contains water, and the recycling treatment of the sludge cannot be achieved. Removing the water in the sludge is not conducive to the subsequent treatment of the sludge. Therefore, the utility model proposes an agricultural farm waste and wastewater treatment and recycling device to solve this problem. Utility Model Content

[0023] In this embodiment, by designing the sedimentation tank 1 into a cone, it is convenient for the sedimentation of silt, so that the silt gathers and settles to the bottom of the sedimentation tank 1. By fixing the horizontal plate 2 on the top of the sedimentation tank 1, the installation of the silt lifting mechanism 3 and other components is realized.

The silt lifting mechanism 3 is composed of a feeding cylinder 301, a rotating rod 302 and a spiral blade 303. The feeding cylinder 301 is vertically arranged on the inner side of the sedimentation tank 1. When the rotating rod 302 rotates, it drives The spiral blade 303 rotates, and then the rotating spiral blade 303 is used to lift and feed the sludge, so that the sludge is transported upward through the feeding barrel 301. By installing a circulation treatment mechanism 5 on the horizontal plate 2, the circulation treatment mechanism 5 can realize the circulation treatment of the sludge and remove the moisture in the sludge. The main part of the circulation treatment mechanism 5 is the cylinder 501. The sludge in the feeding barrel 301 enters the cylinder 501, and then the hydraulic cylinder 506 drives the pressure plate 504 to move, thereby removing the moisture in the sludge, which is convenient for the treatment of the sludge.

[0024] Specifically, the drainage pipe connected to the bottom of the cylinder 501 extends into the sedimentation tank 1 through the hole opened on the horizontal plate 2.
