표고(Lentinula edodes), 노루궁뎅이(Hericium erinaceus), 느타리(Pleurotus ostreatus)의 버섯수확후배지(spent mushroom substrate, SMS)를 퇴비화에 활용하였다. 퇴비화 온도변화는 50oC 이상에서 7일에서 10일 동안 지속 되어 30일에 부숙이 완료되었다. 퇴비화 된 LeCSMS, HeCSMS는 130%, 80% 무종자에 대한 종자 발아지수를 보여 부숙도에 대한 종자 발아지수를 충족하였다. 퇴비화에 따른 물리 화학적 변화를 조사한 바 pH 범위가 4-5 에서 6-7로 증가 되었고 EC는 1-1.4 dS/m로 소폭 감소 되었으며 유기질 함량은 LeCSMS에서 36.9%로 SMS에 비하여 60% 이상 가장 큰 폭으로 감소 되었다. LeCSMS 를 기준으로 N (1.2%), P(2.3%), K(0.77%)함량이 조사되었으며 중금속은 모든 CSMS에서 기준치 이하였으며 Ca, Mg는 30%에서 60%이상 증가하였다. C/N비는 LeCSMS, HeCSMS에서 15% 낮았으나 PoCSMS에서 32%로 높게 나타났다. LeCSMS 처리에 따른 고추 유묘 생육효과는 시판 유기퇴비 처리구 등 대조 구에 비하여 초장이 60% 이상 높게 성장했으며 옆폭, 옆장, 옆수에서 다른 대조 구 에 비하여 모두 우수한 생육 효과를 보였다.

It is necessary to develop a mobile water production system in order to provide stable water supply in case of disasters such as floods or earthquakes. In this study, we developed a modular mobile water production system capable of producing water for various uses such as domestic water and drinking water while improving applicability in various raw water sources. The water production system consists of three stages of filtration (sand filtration - activated carbon filtration - pressure filtration) to produce domestic water and an additional reverse osmosis process to produce drinking water. In laboratory and field experiments, the domestic water production system showed excellent treatment efficiency for particulate matter, but showed limitations in the treatment of dissolved substances such as dissolved organic matter. In addition, ultraviolet irradiation was considered as additional disinfection step, because it does not form precipitates of manganese oxides after disinfection. Reverse osmosis process was added to increase the removal efficiency of dissolved substances and the treated water satisfied drinking water quality standards. Fluorescence analysis of dissolved organic matter showed that the fulvic acid-like substances in raw water was successfully removed in the reverse osmosis process. The mobile water production system developed in this study is expected to be used not only in water supply in case of disaster, but also widely used in islands and rural area.
