摘要
对一堆地面城市垃圾的稳定进行了为期五个月的监测。定期测量二氧化碳演化、温度、湿度、有机物和pH值。在嗜热期，0.1 M Na4P2O7 + 0.1 M NaOH萃取的有机质腐殖质化指数(HI)随时间线性下降，从1.4左右下降到0.4左右。桩侧翻转导致HI值下降，但静桩温度每达到65℃，HI值再次升高。水提物腐殖化指数(HIw)在表层4 d后达到最大值，在30 cm深度11 d后达到最大值。在嗜热期，HIw值随时间呈双曲线下降。
Humification index (HI) as evaluation of the stabilization degree during composting
The stabilization of a pile of ground urban refuse was monitored during five months. Carbon dioxide evolution, temperature, moisture level, organic matter, and pH were measured regularly. The humification index (HI) of organic matter extracted by 0.1 M Na4P2O7 plus 0.1 M NaOH was found to decrease linearly with time during the thermophilic phase from about 1.4 to 0.4. Turning of the pile caused a drop in the HI values, but the index increased again every time the temperature of the static pile reached 65°C. The value of the humification index in water extracts (HIw) reached a maximum after 4 d in the superficial layers and after 11 d at a depth of 30 cm. HIw values were found to decrease hyperbolically with time during the thermophilic phase.
