Abstract

The invention provides a treating system and treating method for feces in a dairy farm. The treating system is formed by connection of units like a residue removing tank, a grating, a regulating tank, a solid-liquid separator, a hydrolysis-acidification tank, an UASB tank, an anoxic tank, an anaerobic tank, an aerobic tank, a secondary sedimentation tank and a disinfection tank. According to the invention, difficulties in treatment of feces in the dairy farm are all taken into consideration; a combined process of hydrolysis and acidification, treatment with the UASB tank, A / A / O (anoxic-anaerobic-aerobic) treatment and settlement is employed; and the treatment method follows the principles of and concept of circular economy, realizes high-efficiency treatment of high-concentration organic waste water and a great amount of undigested fiber in cow dung, recovers biogas, reduces investment cost and operation cost for treatment of feces, carries out harmless and economic treatment of feces in the dairy farm as much as possible, and can meet demands of treatment of feces and sewage in the dairy farm.

Description

technical field

[0001] The invention relates to a manure treatment technology, in particular to a manure treatment system and a treatment method of a dairy farm. Background technique

[0002] With the continuous expansion of breeding scale and the increase in the number of intensive dairy farms, the environmental pollution caused by large-scale dairy farm manure is causing widespread concern in the society.

[0003] Modern large-scale farming will produce a large amount of waste water and manure. Breeding waste water is high-concentration organic waste water rich in a large number of pathogens. It is directly discharged into the water body or stored in an inappropriate place. It may cause surface water or Serious deterioration of groundwater quality.

[0004] The feces and sewage from dairy farms are difficult to treat with high-concentration organic wastewater. The indexes of CODcr (chemical oxygen demand) and BOD5 (biochemical oxygen demand) are high, and the contents of ...
