고형연료화 장치를 이용한 축산분뇨의 활용{Utilization of Livestock Excreta Using Solid Fueling System} Utilization of Livestock Excreta Using Solid Fueling System

본 발명은 고형연료화장치를 이용하여 축산분뇨를 효율적으로 활용한다. The present invention efficiently utilizes livestock manure by using a solid fuel conversion system.

최근 서구화된 식습관으로 인한 축산업의 집약적인 발달로 국내에서 발생되는 대량의 축산분뇨는 막대한 비료자원으로서의 역할과 동시에 한편으로는 주변 환경의 오염원으로까지 인식하게 되었는데 이는 일부 농가에서 축산분뇨의 방치, 무단 방류 등으로 토양 및 수질오염 유발에 대한 우려, 악취 및 해충발생 등에 기인한 것으로서 축산분뇨 처리와 환경문제 해결에 대한 요구와 관심이 주변 및 사회 전반에서 증대되고 있는 실정이다. Recently, due to the intensive development of livestock industry due to westernized eating habits, a large amount of livestock manure generated in Korea has been recognized as a huge fertilizer resource and a source of pollution in the surrounding environment. This is due to concerns about soil and water pollution caused by discharge, odors, and pests, and the demand and interest for livestock excreta treatment and environmental problems are increasing in the surrounding area and society as a whole.

이와 더불어 해양오염방지법 시행규칙에 따라 유기성 폐기물은 해양배출이 점차 어려워지고 있으며, 축산업 종사자들의 가장 큰 애로사항 중 하나로는 축산분뇨처리의 어려움이 뽑히고 있다. In addition, according to the enforcement regulations of the Marine Pollution Prevention Act, it is becoming increasingly difficult to discharge organic wastes to the sea.

축산분뇨는 순수 비료기능 이외에 토양개량(물리ㆍ화학ㆍ생물성) 등 친환경 농업에 기여할 수 있으나 비료성분이 불균형적이고, 살포시 많은 비용과 노동력이 요구되어 화학비료와의 경쟁에서 현실적으로 불리한 면이 있어 비료 자원화가 어려운 실정이고, 축산분뇨는 고농도 유기성 물질로 발생 및 처리과정에서 심한 악취발생으로 인근주민 민원이 발생되고, 일부 비위생적인 축사관리도 환경오염을 가중시킬 우려가 있다. Livestock manure can contribute to eco-friendly agriculture such as soil improvement (physical, chemical, biological) in addition to the pure fertilizer function. It is difficult to turn it into a resource, and livestock manure is a high-concentration organic material, and there is a risk of aggravating environmental pollution due to the generation of severe odors during treatment and complaints from nearby residents.

따라서 축산분뇨를 효율적으로 처리 및 이용할 수 있는 장치의 개발로 축산분뇨의 활용도를 높이는 방법이 요구되고 있는 실정이다. Therefore, there is a need for a method to increase the utilization of livestock manure by the development of a device that can efficiently process and use livestock manure.
