The non-isothermal drying behavior and kinetics of human feces (HF) were investigated by means of thermogravimetric analysis to provide data for designing a drying unit operation. The effect of heating rate and blending with woody biomass were also evaluated on drying pattern and kinetics. At low heating rate (1 K/min), there is effective transport of moisture, but a higher heating rate would be necessary at low moisture levels to reduce drying time. Blending with wood biomass improves drying characteristics of HF. The results presented in this study are relevant for designing non-sewered sanitary systems with in-situ thermal treatment.
通过热重分析研究了人类粪便（HF）的非等温干燥行为和动力学，以便为干燥单元操作的设计提供数据。还评估了加热速率以及与木质生物质混合对干燥模式和动力学的影响。在低加热速率（1 K/分钟）下，水分有有效的传输，但在低水分含量时需要更高的加热速率以减少干燥时间。与木质生物质混合可改善HF的干燥特性。本研究中呈现的结果对于设计具有原位热处理的无下水道卫生系统具有重要意义。
