Device and method for treating breeding wastewater in cattle farm

Abstract

The invention relates to the technical field of wastewater treatment devices, particularly to a treatment device for breeding wastewater in a cattle farm. The treatment device comprises a treatment pool, wherein a sedimentation tank is arranged at the middle portion of the treatment tank; a wastewater treatment cylinder is arranged above the middle part of the sedimentation tank; the outer wall ofthe bottom of the wastewater treatment cylinder is fixedly connected with the bottom of the sedimentation tank through a plurality of mounting rods; a cylindrical coaming is arranged outside the wastewater treatment cylinder in a surrounding manner; the lower end of the coaming is vertically connected with the bottom of the sedimentation tank; filter holes are uniformly distributed in the surfaceof the coaming; a cylindrical bottom tank is arranged at the middle portion of the sedimentation tank; a water lifting cylinder is mounted in the bottom tank in a sliding manner; a cylindrical waterlifting groove is formed in the top of the water lifting cylinder; a partition plate is arranged at the middle portion of the wastewater treatment cylinder; a containing groove is formed in the bottomof the wastewater treatment cylinder below the partition plate; and the outer wall of the water lifting cylinder is in sliding fit with the inner wall of the containing groove after the water liftingcylinder ascends. According to the invention, the wastewater treatment device is allowed to stably work for a long time.

Description

technical field [0001] The invention relates to the field of wastewater treatment devices, in particular to a treatment device and method for cattle farm wastewater. Background technique [0002] Cattle farms will produce a large amount of breeding wastewater, which is mainly composed of urine, residual feces, feed residue and washing water, and some factories also include domestic wastewater generated during the production process. The fecal sediment and suspended matter in the breeding sewage are very high. This kind of sewage belongs to high-concentration organic wastewater and contains a large number of E. coli and microorganisms. In the prior art, methods such as sedimentation and filtration are often used for treatment. Although wastewater can be treated, it is prone to clogging, requires frequent maintenance, and does not have the ability to work stably for a long time. Contents of the invention [0003] The purpose of the present invention is to solve the shortcom...
