| 摘 要： | 以生活垃圾为堆肥原料进行好氧堆肥，对其堆肥过程中C／N、温度、有机质等因素的变化规律进行研究。堆肥的温度明显地呈现出三个阶段，且温度在55℃以上的时间为8天；pH值总趋势为下降-上升-下降；有机质总趋势是逐渐减少，最大降幅为23％；全氮含量呈逐渐下降的趋势，堆肥后期逐渐稳定；氨氮含量呈下降的趋势，硝态氮含量呈上升的趋势；C／N比下降趋势不显著。

| Abstract: | A aerobic composting system using the municipal solid wastes conducted to probe the property variety during composting process,such as C/N,temperature and organic matter.There were three stages of the compost temperature,meanwhile its temperature above 55℃ was 8 days The general trend of pH was falling-decline-falling.The general trend of organic matter was decreasing gradually,and the largest drop range was 23%.The total nitrogen content trend was gradually declining and then tended to maintain stabilization in the final period of composting process.Amino nitrogen content showed a downward trend,on the contrary,nitrate nitrogen content showed an upward trend.The C/N ratio did not show a tendency of decline distinctively. |
