Study on Pretreatment and Kinetics of Waste Klebsiella Pneumoniae by the Autothermal Thermophilic Aerobic Digestion Process

摘要

A innovative pretreatment technique and its kinetics for treating waste klebsiella pneumoniae strains from 1, 3-propanediol (1,3-PD) fermented product by auto thermal thermophilic aerobic digestion (ATAD) process were investigated in laboratory scale to inactivate and reduce pathogens, which was a pretreatment process of the up-flow anaerobic sludge bed (UASB). The feed total suspended solids (TSS), pH value, Redox potential, temperature released by self-heating, and the numbers of pathogens were conducted. The results showed that TSS removal rate and the temperature reached 62.75% and 65¿ respectively, the pathogens'' removal rate was 100%, the results from new kinetic model developed for the ATAD process had a good agreement with actual results.
