摘　　要：利用豆秸秆和木屑形成体积比1∶1作为生态厕所反应基质处理人粪便,得到一种副产品——有机肥料。与传统好氧堆肥过程相比较,获得这种副产品的过程优于传统好氧堆肥过程。通过进行氮、磷、钾、有机物和pH值的检测,结果表明,免水资源综合利用型生态厕所最终产物成分含量:氮4.30%,磷1.06%,钾2.03%,有机物总量79.2%,pH值8.25。这说明最终产物是一种高效的有机肥料。Using mixed material that is composed of 1：1 beanstalk and sawdust in volume as matrix of eco-toilet, automatic heating and mixing systems can keep a continuous thermophilic-aerobic biodegradation process and a uniform temperature in the eco-toilet. So microorganism could be better to treat human feces, the human feces and urine could be composted to produce organic fertilizer as by-products rich in N, P and K. Compared to traditional aerobic composting, the process to get organic fertilizer was superior to traditional aerobic composting. Change of pH value was divided into three phases： acid phase, alkaline phase, stable phase, with pH value of final products in eco-toilet being 8.25. The temperate in the eco-toilet was between 40 ℃ and 50 ℃, water content was 40%～60%, the total reduction rate of dry weight increased gradually from 46.9% to 92.2%. T-N, T-P and T-K contents were increased with feces and urine inputted generally, with their contents being 4.30%, 1.06% and 2.03% respectively finally, and the organic matter content was evidently decreased from 95.6% to 79.2%. The high-efficient organic fertilizer was got finally.
