【摘要】 好氧堆肥技术越来越多地应用于市政污泥处理项目,在工业生产中也遇到了一些实际问题。为了找出并解决困扰低温好氧堆肥的因素,中试使用中型堆肥槽装置完成冬季好氧堆肥过程,与大槽生产相比,中型堆肥槽具有便于过程控制、工艺选择灵活、成本低等特点。使用好氧堆肥复合菌剂与几种调理剂对堆肥物料进行改良,通过堆肥工艺和理化指标综合分析了冬季堆肥过程的部分影响因素,并对工业化堆肥生产提出了建议。更多还原

【Abstract】 Aerobic composting technology has been increasingly used in municipal sludge treatment projects,but the industrial production has encountered some problems. To solve the problems in aerobic composting with low temperature,a medium size compost slot device was used to test the aerobic composting process in winter in a pilot-scale experiment. Compared to the industrialized production,the device was easier for process control and had lower cost. The experiments used microbial agent and several amendments for composting. Some of the composting process factors were explored through the composting process analysis and the chemical analysis. Recommendations to improving composting of industrialization production were provided.更多还原
