Abstract

The invention relates to a large breeding farm waste treatment device which comprises a solid and liquid treatment system and a smelly gas treatment system.The solid and liquid treatment system comprises a methane tank, a straw filter tank, a first sand filter tank, an aerobiotic catalytic oxidation tank, a second sand filter tank and a clean water tank.The methane tank is of a cylindrical structure and is provided with a methane tank feeding port used for waste water, excrement and treated straw to enter.The straw filter tank is of a cuboid structure, and a straw filter tank water inlet pipe is arranged on the upper portion of the straw filter tank and is communicated with a straw filter tank water distribution pipe.Outlet water of the second sand filter tank enters the clean water tank to be recycled.The smelly gas treatment system comprises a draught fan and a smelly gas alkalization absorption tank; after smelly gas enters the smelly gas alkalization absorption tank, pollution substances in the gas are subjected to a chemical reaction with an alkali solution, and the smelly gas is treated into clean gas which is emitted with the standard met.

Description

technical field [0001] The invention relates to the field of environmental protection technology, in particular to a large-scale farm waste treatment device and method. Background technique [0002] During the operation of large-scale farms, they not only produce a large amount of solid pollutants such as feces, but also waste water such as urine and flushing water, as well as atmospheric pollutants such as odor. Pollutants from large-scale farms may pollute the environment during collection, storage, transportation, treatment, and utilization. If they are not properly treated and disposed of, they will pose a great threat and harm to water, air, soil, and human health. , which has a huge negative impact on the sustainable development of the aquaculture industry itself. [0003] Breeding wastewater can be returned to the field or treated by natural treatment systems, but both of these treatment modes require a large amount of land, which is restricted by the national condit...
