基于枯枝落叶堆肥资源化利用初探

The Research of Resource Utilization of Litter Composting

校园绿化产生枯枝落叶及其它绿化废弃物的处置是一个日趋紧迫的问题。本研究以郑州大学校园内产生的枯枝落叶等为原料,通过添加腐熟菌剂,采用静态好氧堆肥方式,对枯枝落叶生产有机肥的资源化利用可行性进行探究。实验结果表明:以枯枝落叶作为堆肥原料品质良好,腐熟效果好,堆肥温度在24 h内上升到50℃以上,并且高温持续到第15天。腐熟产品的理化性质为:有机质含量71.86%,总养分7.62,pH为8.0,经第三方检测各项指标符合《有机肥标准》(NY525-2012)。

The disposal of Campus greening produces litter and other green waste is an increasingly pressing issue.In this study, the feasibility of resource utilization of litter production was studied by adding the decomposing agent and using static aerobic composting method.The results showed that litter was good as a raw material for composting, and the composting temperature was increased to above 50℃ in 24 h, and the high temperature continued to the 15th day. The physical and chemical properties of the ripe products： organic matter content 71.86 %, total nutrient 7.62, pH=8.0, it meets the ＂organic fertilizer standard＂ （NY525-2012） by the testing of the third party.
