Abstract
축산분뇨는 화학적산소요구량과 구리함량이 각각 평균 930,726±380.801 mg/kg와 679±341 mg/kg으로 높아 해양투기 시에는 해양환경에 악영향을 초래할 수 있다. 반면에 육상에서는 유기물 분해를 통해 발생되는 바이오가스 에너지 활용과 양질의 축산분뇨는 풍부한 질소 및 인을 함유하여 퇴비로서의 충분한 경제적 가치를 갖고 있다. 그럼에도 불구하고, 우리나라 축산분뇨 해양투기량은 1997년에 51천 m3에서 시작되어 2005년 2,745천 m3으로 급격히 증가하였고, 2007년 폐기물 해양투기량(7,451천 m3)에서 축산분뇨는 약 27%로서 큰 비중을 차지하였다. 축산분뇨 해양투기 비용은 20,000~33,000원으로서 퇴비 (20,000원), 정화처리 (10,000원)보다도 높지만, 축산농가들은 아직도 퇴비와 정화처리 등 육상 활용보다는 해양투기를 선호하고 있다. 이에 따라 본 소고에서는 축산농가들의 해양투기 선호 요인들에 대한 분석을 통해 개선안을 제시하여 축산분뇨 해양투기로부터의 해양환경오염을 방지하고자 한다.



The average concentrations of COD and copper in the livestock sludge are 930,726±380.801 mg/kg and 679±341 mg/kg, respectively. Due to the high concentrations, dumping to the sea of the sludge could pose potential adverse effects to the marine environment. On the contrary, it could have economic advantages on land as the energy of biogas generated by decomposition of organisms and the compost in case of the sludge of good quality with the abundant nitrogen and phosphorus. Nevertheless, the amount of livestock sludge dumped to the sea in Korea increased sharply from 51,000 m3 in 1997 to 2,745,000 m3 in 2005. And also it had the high proportion of 27% in total amount of waste dumped into the sea (7,451,000 m3 ) in 2007. It might cost between 20,000 won and 33,000 won to dump to the sea of the sludge. In comparison, it might cost 20,000 won to com- post the sludge. And its purification treatment even might cost just 10,000 won. It means that the disposal of the sludge at sea is the most expensive method to deal with the sludge, but ranchers, who engage in the livestock industry, still prefer the disposal at sea to the other methods on land such as the compost and purification treatment. In this article, therefore, we would analyze various factors in the ranchers' preference for the disposal of the sludge at sea, and then we could suggest some legal improvements to prevent and reduce pollution of the sea.
