We investigated the simultaneous degradation of diesel oil in soil and the organic matter in food waste by composting in 8 l reactors. Using a 0.5 l/min air flow rate, and 0.5-1% diesel oil concentrations together with 20% food waste, high composting temperatures (above 60 degrees C) were attained due to the efficient degradation of the food waste. Petroleum hydrocarbons were degraded by 80% after only 15 days composting in the presence of food waste. In a 28 l reactor scale-up experiment using 1% oil, 20% food waste and 79% soil, removal efficiencies of petroleum hydrocarbons and food waste after 15 days were 79% and 77%, respectively.
我们在8升反应器中通过堆肥研究了土壤中柴油和食物垃圾中有机物的同时降解情况。使用0.5升/分钟的空气流速、0.5 - 1%的柴油浓度以及20%的食物垃圾，由于食物垃圾的高效降解，堆肥温度达到了较高水平（高于60摄氏度）。在有食物垃圾存在的情况下，仅堆肥15天后，石油烃的降解率就达到了80%。在28升反应器的放大实验中，使用1%的油、20%的食物垃圾和79%的土壤，15天后石油烃和食物垃圾的去除效率分别为79%和77%。
