Abstract
The NaCl contents of food waste composts made by various techniques known up to now were under the level of 1% by fresh weight basis. But these techniques has some problem that is environment pollution from treated water and high equipment cost. The application to agricultural land of food waste compost that is not sufficiently removed NaCl was considered to be improper due to salt accumulation in soils and plant growth inhibition by salt stress. The purpose of this study is to decompose NaCl in food waste compost using triple salt and this method is differ from existing chemical method. Also, reaction of NaCl with triple salt produced KCl that is basic material of potassium fertilizer. Moreover Also, there was temperature rise of average
음식물 쓰레기로 만든 퇴비 중의 염분함량을 1% 이하로 조절하기 위해 지금까지 여러 가지 방법이 개발되었다. 그러나 이런 방법들은 침출수 과다로 인한 환경오염 또는 높은 설치비 등의 문제를 가지고 있어 실용화에 어려움이 있다. 염분이 충분히 제거되지 않은 음식물 쓰레기로 만든 퇴비를 농지에 사용할 경우 염해로 인한 식물의 성장 장애 및 염류축적이 일어날 수 있다. 본 연구는 음식물 쓰레기 퇴비에 함유된 염분을
