Abstract

In order to develop liquid fertilizer using rendering by-product, rates and velocities of degradation from rendering by-product using pig cadaver investigated under different amount of injection and time with degradation agents (KOH, NaOH, $HNO_3$ and $H_2SO_4$). The amount of residue by degradation agent of $HNO_3$ treatment method was higher than that in KOH, NaOH and $H_2SO_4$ treatment methods. The degradation velocities (K; $hr^{-1}$) of rendering by-product in KOH treatment method were higher in the order of 25% ($0.0309hr^{-1}$) > 30% ($0.0268hr^{-1}$) > 20% ($0.0142hr^{-1}$) > 15% ($0.0111hr^{-1}$) > 10% ($0.0102hr^{-1}$) of weight of rendering by-product. In all conditions, the degradation velocity of rendering by-product using $H_2SO_4$ 30% of weight of rendering by-product was rapid than that for KOH, NaOH and $HNO_3$ treatment methods. Degradation rates of rendering by-product using NaOH were similar to that of KOH and $H_2SO_4$ except for $HNO_3$ under injecting 25% and 30% of rendering by-product weight.

현행 살처분 가축사체의 처리방안 중 하나인 랜더링 처리방법을 사용하여 나온 부산물을 액비화 시키기 위해 산 및 알칼리 분해제를 사용하여 액화시켰으며, 분해제별 주입량 및 처리시간에 따른 랜더링 부산물의 분해율과 분해속도를 조사하였다. 산 및 알칼리 분해제별 주입량 및 처리시간에 따른 랜더링 부산물의 잔존량을 조사한 결과 분해제 중 가장 높은 잔존량을 나타낸 것은 $HNO_3$으로 다른 분해제는 10분이 경과한 후 랜더링 부산물의 잔존량이 대부분 50% 이하로 나타났다. 랜더링 부산물의 분해속도 K ($hr^{-1}$)는 KOH의 경우 랜더링 부산물 무게 대비 25% > 30% > 20% > 15% > 10%순으로 25%를 넣어줬을 때 가장 빨리 분해가 되었다. $H_2SO_4$의 경우 랜더링 부산물 무게 대비 30% > 25% > 20% > 15% > 10%순으로 넣었을 때 빨리 분해되었으며, NaOH도 이와 비슷한 경향이었다. 분해제별 랜더링 부산물의 분해율은 $HNO_3$의 경우에는 순도가 약 61% 정도로 다른 분해제들보다 낮아 분해율이 현저히 떨어졌으며, KOH, NaOH 및 $H_2SO_4$의 경우에는 랜더링 부산물을 25%와 30%를 넣었을 때 큰 차이가 없어 경제성 및 효율성을 고려하였을 때 분해제를 랜더링 부산물의 무게 대비 25%를 넣었을 경우가 가장 적합하다고 판단된다.
