슬러리 돈사나 분뇨가 혼합되어 배출될 경우에는 어떻게 하는가? | 가축분뇨는 일반적으로 분과뇨가 분리될 경우 뇨와 오수는 일반적인 정화방법 (물리, 화학, 생물학적 처리)으로 처리하고 분은 수분을 조절한 후 부산물 비료 또는 퇴비로 자원화되어 토양에 환원된다. 슬러리 돈사나 분뇨가 혼합되어 배출될 경우에는 저장 액비화 방법에 의해 액비탱크에서 일정기간 부숙 시킨 후 토양에 살포하거나 고액분리 장치 등으로 분뇨를 정화처리 하거나 자원화한다. 주된 정화처리인 생물학적 처리는 축산폐수에 함유된 고농도 암모니아 독성에 의한 아질산염 축적 및 질산화 저해 등으로 인한 낮은 질소 제거 효율이 문제가 되고 있고(An et al. | |

결정화 반응에 의해 생성된 struvite에 대한 우리나라의 실정은 어떠한가? | , 2000; Yetilmezsoy and Sapci-Zengin, 2009;Cerrillo et al., 2015; Ryu and Lee, 2016), 우리나라에 서는 아직까지 법적 요인 및 인식 등의 부족으로 struvite가 자원화 방안으로 검토되거나 활용되지 못하고 있는 실정이다. 따라서, 가축분뇨로부터 회수한 struvite의 자원 활용 가능성에 대한 기술적, 경제적 분석은 struvite의 제도권 진입 및 상업화에 중요한 역할을 담당할 수 있을 것으로 판단된다. |
