摘　　要：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、p H、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,p H,N transformation 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.
