- Title:
- Effect of Additional Heating Source on Bio-drying of Typical Organic Wastes
- 摘要:
- 通过对典型有机废弃物进行生物干化实验，探究了外加热源对生物干化效果的影响。在不加热和40 ℃加热两个条件下，对果蔬、厨余和园林垃圾等典型有机废弃物的生物干化效果进行了比较。结果发现，外加热源对不同基质干化效果的影响程度不同，但能够明显提升有机废弃物生物干化的效果。加热可使得反应器保持高温状态，使基体长期处于微生物代谢旺盛阶段，有利于生物干化。果蔬与园林垃圾协同干化时，升温累积值在10 d后达到了151 ℃·d，比不加热条件下高出111%。在加热条件下，园林垃圾独立干化的最终含水率能降到10.34%、生物干化指数为2.54、低位热值为13 920.8 kJ/kg，优于不加热条件。
- Abstract:
- Effect of additional heating source on bio-drying of typical organic wastes was investigated by bio-drying experiments. The bio-drying effect of typical organic wastes (such as fruit and vegetable waste, kitchen waste and garden waste) with 40 ℃ heating or without heating was compared. The effects of additional heating source on different substrates were quite different, but heating could significantly improve the bio-drying efficiency of all organic wastes. Heating could keep the reactor at a high temperature and make the substrate degradation in the vigorous metabolism stage for a long time, which was beneficial to bio-drying. When fruits and vegetables were dried together with garden wastes, the cumulative value of heating reached 151 ℃·d after 10 days, which was 111% higher than that without heating. Under the condition of heating, the final moisture content of garden waste could be reduced to 10.34%, the bio-drying index was 2.54, and the lower heating value (LHV) was 13 920.8 kJ/kg, which were better than those without heating.
