摘要

摘要本研究以玉米秸秆为过滤材料，对厌氧消化粪肥浓缩液进行预处理，研究了堆肥玉米秸秆的性能。结果表明，玉米秸秆能有效去除消化液中的悬浮物和有机物。用过的玉米秸秆可以直接堆肥。堆肥温度迅速升高，并在嗜热阶段保持10分钟以上天。在28 经过几天的堆肥，用过的玉米秸秆可以成熟，基质pH为7.37，电导率为1.13 mS/cm，发芽指数高于100%。在堆肥过程中，使用过的玉米秸秆的碳氮比从16.81下降到13.62。此外，在堆肥过程中，用过的玉米秸秆中的纤维素降解了约35.4%。

Composting of Cornstalks Used as Filtering Materials for the Pretreatment of Anaerobically Digested Centrate

Abstract This study investigated the performance of composting cornstalks after used as the filtering materials for the pretreatment of anaerobically digested manure centrate. Results show that cornstalks could effectively remove suspended solids and organic matter in digested centrate. Direct composting of the used cornstalks could be achieved. The composting temperature increased rapidly and maintained at the thermophilic phase for more than 10 days. During 28 days of composting, the used cornstalks could be mature as indicated by the matrix pH of 7.37, electrical conductivity of 1.13 mS/cm, and germination index of higher than 100%. During composting, the carbon/nitrogen ratio of the used cornstalks decreased from 16.81 to 13.62. Moreover, cellulose in the used cornstalks was degraded by approximately 35.4% during composting.
