- 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.
