摘要
采用蚯蚓堆肥处理4种不同有机废物,通过分析样品的温度、有机分含量、pH值以及实验前后样品的质量等参数的变化,比较蚯蚓堆肥处理不同有机垃圾的效果。实验结果表明:1.在合理条件下,蚯蚓堆肥可以直接处理生活有机垃圾和污泥(包括其堆肥后产物);2.在同样的实验条件下,蚯蚓堆肥处理生活有机垃圾和污泥及其堆肥后产物过程中,其处理城市生活有机垃圾的效果最好,减量化和物降解率分别为69.8%和75%。
Vermiconposting experiments were conducted to determine the effects of treatment on four organic wastes through analyzing the change of parameters, including the temperature,organic eontent,pH and quality etc. Experiment shows：1. In the good condition, vermicomposting can be used to treat with bioorganie household waste and sludge （including eomopsting productions ） directly; 2. In the same experimental condition, vermicomposting is more fitted to treat with the latter bioorganie household waste during the four samples, the lost of mass and the biodegradability is 69.8% and 75% respectively.
