Autothermal Thermophilic Aerobic Digestion Process and its Kinetic Model for Pretreating Klebsiella Pneumoniae Waste

Abstract:

An autothermal thermophilic aerobic digestion (ATAD) and its kinetics were studied for pretreatment of waste Klebsiella pneumoniae strains from 1, 3-propanediol (1, 3-PD) fermented product. The total suspended solids (TSS), pH value, Redox potential and temperature variation by self-heating were investigated, including the numbers of pathogens. The results showed that TSS removal ratio and the temperature reached 62.75% and 65 °C respectively. Besides, the pathogens removal ratio was 100%. By using a patch-typed process of ATAD for pre-treating waste Klebsiella pneumoniae strains from 1, 3-propanediol, TSS removal ratio can reach 65.0%, solids retention time of 13 d. The relative deviation between the calculated and experimental values is less than 12.80%, and the results from the kinetic model developed for the ATAD process had a good agreement with the experimental results.
