NOVELTY - Breeding farm waste treatment system comprises a biogas station and a sewage processing sub-system, where the sewage processing sub-system is used for processing discharge of sewage and rain water. The biogas station comprises a collection tank, a regulation tank, a dry-wet separation machine, an organic fertilizer semi-finished product workshop, a biogas fermentation tank, a biogas harmless processing module, a biogas storage tank and a biogas transportation module. The collection tank is connected with regulation tank. The regulation tank is set with input of dry and wet separation machine.    USE - Used as a breeding farm waste treatment system.    DETAILED DESCRIPTION - Breeding farm waste treatment system comprises a biogas station and a sewage processing sub-system, where the sewage processing sub-system is used for processing discharge of sewage and rain water. The biogas station comprises a collection tank, a regulation tank, a dry and wet separation machine, an organic fertilizer semi-finished product workshop, a biogas fermentation tank, a biogas harmless processing module, a biogas storage tank and a biogas transportation module. The collection tank is connected with the regulation tank. The regulation tank is connected to the input of dry and wet separation machine. The dry and wet separation machine is provided with a solid material outlet and a liquid material outlet, which are connected to the organic fertilizer semi-finished product workshop and the biogas fermentation tank. The biogas fermentation tank, the biogas harmless processing module, the biogas storage tank and the biogas transportation module are sequentially connected. The collection tank collects sewage and conveys into the regulation pool for precipitation to remove large particles of inorganic matter. The manure in regulation tank is separated via dry and wet separation machine into solid material and liquid material respectively discharged from solid material outlet and liquid material outlet into organic fertilizer semi-finished product workshop and biogas fermentation tank, where organic fertilizer is obtained by semi-finished product workshop, and biogas is produced from fermentation tank. Passing biogas into biogas harmless processing module to filter out harmful components, then storing in biogas storage tank. The biogas stored in biogas storage tank is transported for energy supply by biogas transportation module.
