Start-up and Performance Characteristics of a Trickle Bed Reaktor Degrading Toluene

Original language description

The objektive of this work was to evaluate toluene degradation in a trickle bed reactor when the loading was carried out by changing the air flow rate. The biofiltration system was inoculated with a mixed microbial population, adapted to degradation of hydrophobic compounds. Polypropylene high flow rings were used as a packing material. The system was operated for a period of 50 days at empty bed residence times ranging from 106s to 13s and with a constant inlet concentration of toluene of 100 mg.m-3. The reactor showed high removal efficiency at higher contact times and increasing elimination capacity with higher air-flow rates. The highest EC value reached was 9.8 gcm-3.h-1at EBRT = 13s. During the experiment, the consumption of NaOH solution was also measured. No significant variation of this value was found and an average value of 3.84 mmol of NaOH per gram of consumed carbon was recorded

Vliv provozních charakteristik zkrápěného náplňového reaktoru na degradaci toluenu

Czech description

Předmětem práce byla degradace toluenu v náplňovém biofiltru s proměnlivým proděním vzduchu. Biofiltr byl inokulován směsnou mirobiální populací, nosičen byl perlit. Doba trváním pokusu 50 dní, vstupní koentrace 100 mg.m-3. Je studován vliv účinnost, doba zdržení a vliv průtoku vzduchu. Byly zjištěny provozní charakteristiky biofiltru a degradační rychlost
