Aerobic thermophilic digestion of fecal matter: Condensate recovery, low solids production, and water reuse

A bench-scale thermophilic sequencing batch reactor (SBR) was designed, fabricated, and tested for the recovery of clean water and the reuse of condensate. The SBR reactor was non-Fouling and membrane-free, Aerobic, low-Solids producing, and Thermophilic (FAST). Accelerated treatment of domestic wastewater organic matter enabled 99.9 % removal of total suspended solid (TSS) from influent loads and 99.8 % removal of chemical oxygen demand (COD) loads. The FAST system also ensured efficient pathogen inactivation, substrate utilization, and biomass growth that aligned with experimental results. Future research will focus on scale-up of technology and assessment of performance in diverse environments.

设计、制造了一个实验室规模的嗜热序批式反应器（SBR），并对其进行了测试，以用于清洁水的回收和冷凝水的回用。该SBR反应器无污垢且无膜，需氧，产生的固体量低，且为嗜热型（FAST）。对生活污水中有机物的加速处理使得进水中总悬浮固体（TSS）的去除率达到99.9%，化学需氧量（COD）负荷的去除率达到99.8%。FAST系统还确保了有效的病原体灭活、底物利用以及生物量增长，这与实验结果相符。未来的研究将侧重于技术的放大以及在不同环境中的性能评估。
