摘　　要：[目的]为废物的无害化处理提供理论依据。[方法]采用S-15型生态厕所,大豆秸秆、大豆秸秆和木屑1∶1混合物、稻壳为反应基质处理人体粪便,对相关指标进行监测分析。[结果]大豆秸秆的有机质的降解程度更明显,从95.26%降到76.40%。混合物对人体粪便降解率为71%,稻壳的降解率为62%,大豆秸秆的降解率最高,为78%。稻壳的使用周期最长,为24周。3种基质的氮含量基本呈上升趋势,大豆秸秆处理的最终氮含量比其他2个处理的氮含量高。大豆秸秆处理的总氮磷钾含量为72.19 g/kg,混合物处理的总氮磷钾含量为54.86 g/kg,稻壳处理的总氮磷钾含量为63.16 g/kg,均高于一般堆肥质量要求。[结论]3种反应基质均可以有效地处理人体粪便。[Objective] The objective of the study was to provide a theoretical base for the harmless treatment of waste.[Method] With employed the S-15 bio-toilet,human feces was treated by matrix of soybean straw,the mixture of soybean straw and sawdust（1∶1） and rice husk and the relevant indicators were monitored and analyzed.[Result] The degradation degree of organic matter in soybean straw was decreased markedly from 95.26% to 76.40%.The degradation rate of of human feces treated with mixture was 71%,and that with rice husk reached 62%.The degradation rate of human feces treated with soybean straw was 78%.The using period of rice husk was longest,being 24 weeks.The N contents in 3 matrixes were all had a rising trend.The final N content in treatment with soybean straw treatment was higher than that in other 2 treatments.The content of total NPK in treatment with soybean straw was 72.19 g/kg,that with mixture was 54.86 g/kg,that with rice husk was 63.16 g/kg,being higher than that of the general compost requirement.[Conclusion] 3 matrixes all could treat the human feces effectively.
