摘　　要：[目的]用稻壳处理人体排泄物,实现废物的减量化和资源化。[方法]采用免水式生物反应器,以稻壳作为反应基质来处理人体排泄物,着重研究反应基质中营养元素的含量变化特征和人体粪便的减量化过程。[结果]未粉碎稻壳和粉碎稻壳的干重累积减少率分别为92.40%、81.47%;未粉碎稻壳和粉碎稻壳基质产物中的N、P、K等营养物质含量均较丰富。[结论]未粉碎稻壳和粉碎稻壳基质产物可以作为有机肥。[ Objective ] The research aimed to realize the reduction and reclamation of the waste with degradation of human excreta with rice husk. [ Method ] With the bioreactor of water-free as the test device, the rice husk was used as the reactive matrix for treating the human excreta to mainly study the changes of nutrition elements in reactive matrix and reduction process of human feces. [ Result ] The dry weight reduction rate in accumulation of human feces treated with the uncrushed rice husk was 92.40%, and that with crushed rice husk reached 81.47%. The residues were both rich in N, P and K in treatment with uncrushed rice husk and crushed rice husk. [ Conclusion] The residues could be used as organic fertilizer.
