| titleOfInvention | A disposal method of pig ordure |
| abstract | The present invention relates to a method for treating pig meal, which initially causes an oxidation catalyst reaction in a pig wastewater solution to primarily separate the liquid from a solid, and then promotes the base catalyst reaction with calcined lime and is dissolved in the liquid as a polymer flocculant. The sludge is agglomerated, precipitated and dehydrated to separate the secondary and the first and second separated solids are dried by vacuum evaporator while being neutralized with quicklime and used as organic fertilizer. In addition, the second separated liquid is just discharged or microbial treatment is used as a liquid fertilizer or drinking auxiliary feed, that is, feed water.n n n A characteristic feature of the present invention is that the compound of SO 4 -2 ion and metal cation is lowered to pH (pH) of 3.5 to 6 as a compound of SO 4 -2 ion and metal cation, as opposed to the neutralization treatment and flocculation, as in the standard activated sludge process. In the first step, the oxidation catalyst reaction occurs, and the base catalyst reaction is caused by coagulation with slaked lime. In addition, the present invention reduces the treatment cost per tonne of livestock wastewater from 12,000 to 15,000 won to 4,000 won or less, and can produce organic fertilizer, liquid fertilizer and drinking auxiliary feed, as well as very low initial facility cost and greatly reduce the installation area of equipment. It works. |
