摘 要 ：对城市污泥好氧堆肥稳定化过程的温热条件进行了探讨 ,将物候学中的积温概念应用于堆肥稳定化 (腐熟 )过程。它同时兼顾到堆肥过程中的温度强度和持续时间两个参数。对于采用的强制通风静态垛堆肥工艺 ( CTB自动控制堆肥工艺 ) ,建议以 1 5℃作为生物学零度 ,积温指标为 1 0 0 0 0℃· h左右。堆肥原料的性质、堆肥工艺、微生物种群、生物学零度、外界环境等因素可能会对积温产生一定影响。

Abstract:Accumulated temperature is an important index of the required heat condition during the growth of plant. The accumulated value of daily temperature during the growing period is relatively steady. Like the growing process of plant, the heat condition is also important for the composting process. The two aims of composting process, eliminating pathogen and stabilizing organic matter, all relates to the heat condition. It is necessary to keep the composting process during the moderate temperature for a period ...
