| 摘 要： | 蚯蚓堆肥相比其他污泥处置方式具有工艺简单、无二次污染、运行费用低、蚓粪农用肥效高等优点。概述了污泥堆肥中蚓种的选择,介绍了堆肥处理过程中的4个影响因素:C/N、p H和EC、温度、湿度;列举了目前常用的调理剂种类、作用及其效果;分析了判定堆肥腐熟的5种生化指标:水溶性有机碳(DOC)、氨氮及硝氮(NH+4-N及NO3-N)、固相C/N-、水溶性有机碳/水溶性有机氮(DOC/DON)、种子发芽指数(GI);针对目前存在的问题,对今后的研究方向进行了展望。

| Abstract: | Compared with other sludge disposal methods， vermicomposting has the advantages of simple process，no secondary
pollution， low running cost and high agricultural fertilizer efficiency from earthworm cast． The research outlined the option of
earthworm species in sludge composting． Four influencing factors including C to N ratio，pH and EC， temperature，and
moisture were introduced． It listed the types， function， effect of the normal amendments and analyzed five kinds of chemical and
biological indexes for determining maturity as follows: dissolved organic carbon ( DOC) ， ammonia nitrogen and nitrate nitrogen
( NH +
4 －N and NO3－N) ，C to N ratio in solid phase，dissolved organic carbon to dissolved organic nitrogen ratio ( DOC/DON) ，
germination index ( GI) ． Suggestions on further research were proposed based on the current existing problems． |
