Sewage treatment device for livestock breeding

Abstract

The invention discloses a sewage treatment device for livestock breeding. The sewage treatment device comprises an excrement collector, wherein the excrement collector is connected with a biogas digester through a conveyor belt; the upper end of the biogas digester is connected with a sewage collection pool through a pipeline; the right end of the biogas digester is connected with a desulfurization device; the desulfurization device is connected with a biogas storage tank through a pipeline; the lower end of the biogas digester is connected with a solid-liquid separation device through a pipeline; a biogas residue pool is arranged on the lower part of the solid-liquid separation device; a bio-fertilizer stirring tank is arranged on one side of the biogas residue pool; the right end of the solid-liquid separation device is connected with a hydrolysis acidification pool; the right side of the hydrolysis acidification pool is connected with a first contact oxidation pool; the right side of the first contact oxidation pool is connected with a second contact oxidation pool; the second contact oxidation pool is connected with a disinfecting tank. The sewage treatment device disclosed by the invention has the beneficial effects that the trouble brought to a farm due to lots of livestock excrements and breeding wastewater can be avoided, the environmental damage and pollution can be reduced, and the excrements are changed into pollution-free renewable energy.

Description

technical field [0001] The invention relates to the technical field of sewage device treatment, in particular to a livestock breeding sewage treatment equipment. 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. Therefore, how to effectively and scientifically deal with these livestock manure and breeding sewage has become an urgent problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a sewage treatment device for animal husbandry to overcome the above-mentioned technical problems existing in the prior art. [0004] Technical scheme of the present invention is realized like this: [0005] A sewage treatment device for animal husbandry, comprising a fec...
