The invention discloses a
pollution abatement method for a
livestock and poultry farm. The method comprises the following steps of: separating
feces from fence washing water and rain water at the source; carrying out
solid-liquid separation on the
feces and the
sludge generated in each
treatment procedure; conveying the separated liquid part to a plug flow anaerobic
fermentation reactor or a liquid high-temperature aerobic
fermentation reactor for liquid biological treatment, carrying out aerobic
fermentation and
filtration to get a liquid
organic fertilizer; and conveying the separated
solid part to a high temperature aerobic fermentation device, after fermentation, aging and deeply
processing the
solid part to get a solid
organic fertilizer. Bad smell is exhausted after being processed in a biological deodorization filtering
tower, and the
filter material replaced from the biological deodorization filtering
tower is considered as
carbon source and conveyed to the solid aerobic fermentation device so as to be treated. Firstly, the fence washing water is treated by a grid
impurity removal facility, after being treated by an SBR (
Sequencing Batch Reactor Activated Sludge Process)
biological reactor and medicated for
flocculation and
sedimentation, the fence washing water is drained after being purified by a wet land, or drained after being treated by aerobic fermentation reaction and filtering, and the sedimentary
sludge and the solid substances under the grid fence are conveyed into a solid-liquid
separation procedure so as to be treated. The method can be used for managing or beneficially using all the pollutants, and contributing the effort for establishing the resource-saving and environmentally-friendly society.
