LIQUID LIVESTOCK WASTE TREATING METHOD

摘要

The urine of livestock is introduced into and stored in a urine collector, and the solid matter is separated as necessary from the urine to take out completely liquid excrement having urine as a main component. This liquid excrement is introduced into a treatment tank, to which various kinds of small pieces of rocks and soil humus are added to cause a bioreaction in aerating condition, whereby a humus forming reaction takes place owing to the actions of the soil humus and soil microorganisms contained in the liquid excrement as a raw material. The various kinds of small pieces of rocks added display their functions as catalysts for promoting the humus forming reaction to activate the soil microorganisms, which lead the excrement to the formation of humus, to the ultimate limit. This makes it possible to treat this liquid excrement speedily and efficiently and turn it into an odorless nonpoisonous material, and also turn the liquid excrement into a concentrate of the active soil microorganisms and a metabolic product thereof and utilize the concentrate effectively as an agricultural material.
