Abstract

This study aims to investigate the characteristics of night soil/horse manure with leaf co-composting using aerobic static composting method. Two influencing factors, including composting materials and aeration pattern, were investigated by determining the change in the principal physicochemical properties, i.e. temperature, volatile solid, carbon, nitrogen, hydrogen, carbon-to-nitrogen ratio, heavy metals, ammonia nitrogen, nitrate nitrogen, and germination index (GI). The mixture of horse manure and leaf can achieve high composting temperature, long retention time of high temperature (55 °C), fast organic matter degradation, and high GI under the same aeration pattern. Under the same composting materials, the intermittent aeration pattern during composting was superior to the continuous aeration pattern because the former promoted the composting process.

摘要

本研究旨在研究好氧静态堆肥法与叶复合堆肥的粪便/马粪特性。通过测定主要理化性质的变化，即温度、挥发性固体、碳、氮、氢、碳氮比、重金属、氨氮、硝态氮等两个影响因素，包括堆肥材料和曝气方式。和发芽指数 (GI)。马粪与树叶混合，在相同曝气模式下，堆肥温度高，高温（55℃）停留时间长，有机物降解快，GI高。在相同的堆肥材料下，
