Problems solved by technology

When the device processes it, a single sewage inlet is used, which leads to a slow input of sewage, which affects the rapid progress of sewage treatment. The filtration accuracy of sewage is average, and the sewage and feces separated by filtration are not properly treated. Processing and utilization can easily cause waste of resources

Embodiment 1

[0022] see Figure 1-2 , a sewage treatment device for animal husbandry farms, comprising a lower tank body 10, an upper tank body 11, a sewage inlet pipe 12, and a sewage outlet pipe 14; the top of the lower tank body 10 is fixedly connected with an upper tank body 11 through a sewage inlet cavity 15 , the lower tank body 10 is set to a cylindrical structure, the sewage inlet pipe 12 is set to a circular structure and four sets of sewage inlet pipes 12 are connected at equal intervals around the sewage inlet pipe 12, and the sewage inlet pipe 12 is convenient for simultaneously disposing of multiple positions. The sewage is input into the sewage inlet chamber 15. The end of the sewage inlet pipe 12 located inside the sewage inlet chamber 15 is jointly connected with a group of lower water boards 17 that are inclined downward, through which the sewage that enters through the sewage inlet pipe 12 can flow downward quickly. The upper surface of the lower water plate 17 is fixed...

Embodiment 2

[0027] refer to image 3, on the basis of Embodiment 1, the bottom of the rotating filter body 20 is connected with a feces collection bin 21 outward, and the bottom of the feces collection bin 21 is fixed on the outside of the lower tank body 10 through a support plate, and one end of the support plate is fixed on the lower tank. On the outer wall of the body 10, when the sewage is filtered on the rotating filter body 20, the feces at the bottom of the rotating filter body 20 will easily affect the filtering work of the rotating filter body 20 after a long period of accumulation, so the top of the feces collection bin 21 can be opened and passed Stop inputting the sewage, and push the feces at the bottom of the rotating filter body 20 into the inside of the feces collection bin 21 while the rotating filter body 20 is rotating. The right bottom of the excrement collection bin 21 is connected downwards to the right top of the sedimentation tank 13, and the inner right side of t...

Abstract

The invention relates to the technical field of sewage treatment, and discloses a livestock farm sewage treatment device which comprises a lower tank body, an upper tank body, a sewage inlet pipe anda sewage outlet pipe. The tail ends of the sewage inlet pipes positioned in a sewage inlet cavity are jointly connected with a group of downward inclined drainage plates; a group of multi-stage filterscreen frames are fixedly mounted in the lower tank body on the lower side of the rotary filter body; a plurality of groups of fine filter screens of which the tops protrude upwards are fixedly mounted in the multi-stage filter screen frames; the tail end of a recycling pipeline extends into a settling tank fixed outside the right side of the lower tank body; the tail end of the recycling pipeline is communicated with a group of settling ponds arranged in the settling tank, the bottom of the rotary filtering body is outwards communicated with an excrement collecting bin, the bottom of the right side of the excrement collecting bin is downwards communicated to the top of the right side of the settling tank, and a biogas digester is arranged on the right side in the settling ponds. The device has the advantages of multi-group feeding, high speed, multi-stage filtration, high precision, repeated mixing utilization and maximization of resource utilization.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device for livestock farms. Background technique [0002] The livestock breeding industry will produce a large amount of sewage in the production process. If it is directly discharged, it will cause eutrophication of the water body and cause water pollution. Therefore, a livestock breeding sewage treatment equipment is needed to treat the sewage. [0003] Chinese patent (notification number: CN 109231579 A, ​​announcement date: 2019.01.18) discloses a sewage treatment device for livestock farms, including a bottom plate, the upper surface of the bottom plate is provided with an installation groove, the invention drives the The motor drives the rotation of the stirring shaft to make the stirring in the mixing box more uniform. Start the servo drive motor to drive the second gear, and the first gear drives the rotation of the threaded rod, thereby drivin...
