玉米秸秆作为生态厕所基质处理人粪便的实验研究

利用日本科学技术振兴机构赠送的S-15型生态厕所,以玉米秸秆作为反应基质来处理人粪便,旨在研究玉米秸秆能否代替木屑作为生态厕所的反应基质.实验过程中,对粪便和玉米秸秆混合物的减量化情况、物理性状的变化以及温度、湿度、pH值、有机质、N、P、K等营养元素和碳氮比的变化情况进行了监测.结果表明:玉米秸秆能够代替木屑作为生态厕所的反应基质,且能够有效的降解人粪便,整个反应过程中粪便和玉米秸秆混合物的干重减少率为37.3%.最终残余物的pH值和碳氮比分别为8.02和13.7,且含有大量的N、P、K等营养物质,可以作为有机肥.

The study on the experiment of decomposing human feces by bio-toilet using cornstalk as matrix

In this paper, we researched on the treatment of human feces, which employed the S-15 bio-toilet presented by Japan Science and Technology Agency, and the cornstalk as matrix. In order to study whether cornstalk can replace sawdust as matrix of the bio-toilet, the changes in temperature, water content, pH, organic matter, N, P, K and C/N were investigated in the experiment. The results showed that the cornstalk can be used as matrix in the bio-toilet. The dry weight reduction rate of the mixture is 37.3%. The final pH and C/N were 8.02 and 13.7 respectively. In addition, the final remains contain plenty of N, P and K and can be used as organic fertilizer.
