Abstract

The aim of this study was to determine the appropriate strategy for cattle manure composting with forced aeration. The composting of cattle manure was conducted using an 18.8 L reactor with three different amounts of total air supplied (1080, 3240 and 10,800 L/kg dry mass) during 360 h of composting using continuous and on/off sequencing (20 min/h) aeration methods and three turning patterns (no turning, full turning and turning with position change). The degradation of organic matter in three-stage systems (the compost was turned every 120 h over the 360 h period) was significantly affected by total air supply volume and was large in the case of on/off sequence aeration. The pattern of moisture change was more affected by turning than by aeration modes. The optimal composting conditions for organic matter degradation (maximum of 37.7%) were aeration rate: 0.45 L/min kg dm, aeration mode: on/off sequencing process and full turning. The total accumulated weight losses and heat generated during composting indicated significant effects of the total air supplied and were large in the case of the continuous process.

采用强制曝气策略的填充床反应器中的牛粪堆肥

本研究的目的是确定牛粪强制曝气堆肥的适宜策略。采用18.8 L反应器进行牛粪堆肥，在360 h的堆肥过程中，采用连续开/关(20 min/h)曝气方式和3种翻转模式(不翻转、完全翻转和位置变换)，总供气量为3种(1080、3240和10800 L/kg干质量)。在三级系统中(在360 h期间每120 h翻转一次堆肥)有机物的降解受总送风量的显著影响，在开/关顺序曝气的情况下，有机物的降解很大。湿度变化模式受转向的影响大于曝气方式。有机物降解的最佳堆肥条件为曝气速率:0.45 L/min kg dm，曝气方式:开/关顺序处理和全翻。在堆肥过程中产生的总累积重量损失和热量表明总空气供应的显著影响，并且在连续过程的情况下很大。
