针对中国南海离岸岛礁固体废弃物日益增多的问题,研究了以锯末和玉米秸秆作为调理剂,厨余垃圾 、粪渣和剩余污泥进行好氧共堆肥的可行性,并分析了其在南海岛礁的适用性.结果表明,厨余垃圾-粪渣-剩余污泥共堆肥工程中的温度 、含水率 、pH、氮素转化和损失以及生物毒性的变化基本都符合堆肥要求,特别是厨余垃圾 、粪渣 、剩余污泥 、锯末和玉米秸秆添加量分别为2.000、2.000、2.000、1.500、1.500 kg或者3.000、3.000、3.000、1.125、1.125 kg时.考虑到南海岛礁缺乏调理剂,后者更适合南海岛礁.%Aiming at the issue of increasing solid in reefs located in the South China Sea ,kitchen waste ,feces and sludge co-composting with amendments of saw dust and corn straw was studied ,and its suitability in South China Sea was analyzed .Results showed that parameters of co-composting including temperature ,moisture content ,pH ,N trans-formation and loss ,and biotoxicity almost all accorded to composting conditions ,especially when kitchen waste ,feces , sludge ,saw dust and corn straw dosages were 2 .000 ,2 .000 ,2 .000 ,1 .500 and 1 .500 kg or 3 .000 ,3 .000 ,3 .000 ,1 .125 and 1 .125 kg .Considering the lack of amendments in reefs of South China Sea ,the latter dosages scheme was most suitable .
