Abstract

Aiming at the problems of long treatment cycle and low dehydration efficiency of kitchen waste bio-drying, the effects of different aeration modes (groups with aeration controlled by temperature:TFWD 45-50, TFWD 50-55, TFWD 55-60, TFWD 60-65; groups with aeration controlled by time:TFSJ 20, TFSJ 60) on energy consumption, dehydration efficiency and nitrogen loss of kitchen waste biol-drying, on the bio-drying machine with external auxiliary heating, were evaluated. The results showed that:1) compared with the four treatments of aeration controlled by temperature, the two treatments of aeration controlled by time were with less total nitrogen (TN) and ammonium nitrogen losses, and higher germination index (GI); 2) continuous aeration, TFSJ 60, was with the lowest dehydration efficiency (66.78%), lowest TN and ammonium nitrogen losses (8.14% and 12.96%, respectively), highest maturity (EC was 2.72 mS/cm and GI was 75.00%), and the lowest energy consumption per unit of mass dehydration (1.10 kW·h/kg); 3) TFWD 50-55 was with the highest dehydration efficiency (more than 99%), TN and ammonium nitrogen losses (16.95% and 57.83%, respectively), lower maturity (EC was 4.28 mS/cm and GI was 19.58%), and higher energy consumption per unit of mass dehydration (1.74 kW·h/kg). Pearson correlation analysis results showed that TN and ammonium nitrogen were positively correlated with moisture content (P<0.05), and negatively correlated with temperature, EC and energy consumption (P<0.05). Therefore, continuous aeration (TFSJ 60) was recommended for kitchen waste, if the bio-dried materials were treated by aerobic composting to return to the soil; aeration controlled by temperature (TFWD 50-55) was recommended, if the bio-dried materials were to be incinerated or landfilled. This study could provide references for the selection of aeration mode for the treatment of kitchen waste by external auxiliary heating bio-drying machine.
