Abstract

Advanced countries, animal wastes are produced using bioenergy and methane gas technology. In Korea, many researches are being actively carried out to develop livestock manure as a resource technology rather than a animal waste. However, the production of bio-gas using livestock manure is still in the process of development of functional livestock and compost because of low economic efficiency with livestock manure recycling technology. In this paper, in order to accurately estimate the manure output, It will calculate the manure excretion if you have finished input the number of pigs. In addition, we simulated the fertilization rate of three elements of NPK fertilizer per 100 square meters automatically.

축산 선진국에서는 축산 폐기물을 바이오 에너지 및 퇴비, 액비로 자원화 이용하고 있다. 우리나라에서도 축산분뇨를 더 이상 페기물이 아닌 자원화 할 수 있도록 관련 연구가 활발하게 이루어지고 있다. 그러나 좁은 국토면적과 부족한 농지면적으로 가축분뇨 자원의 전량 자원화에는 어려운 상황이다. 특히 지역적으로 과잉되는 양분은 제2의 환경오염을 유발할 수 있어 지역적으로 잉여되는 양분의 관리기법이 매우 시급한 상황이다. 본 논문에서는 지역적으로 발생되는 가축분뇨 중 함유된 양분량을 정확하게 예측하기 위해서 사육단계별로 돼지 두수를 입력하면 자동으로 분뇨발생량 및 함유양분을 계산하도록 하였다. 또한 이를 통해 발생된 분뇨의 농지환원 시 시비량을 100평당 NPK 비료 3요소로 자동 계산토록 하여 시비량을 산출하는 모의실험을 수행하였다.
