Sažetak:
Tobacco waste poses an important environmental problem as some main components of tobacco waste are harmful and toxic, primarily nicotine. Bioaugmentation of the activated sludge system with specialized bacterial strains may be a powerful way to improve several aspects of wastewater treatment, including a rapid reduction of toxicity to the microbial community. The aim of this work was to study the efficiency of biodegradation of organic pollutants in laboratory prepared leachate from tobacco dust waste under batch conditions using Pseudomonas aeruginosa FN and bioaugmented activated sludge with bacterial culture of P. aeruginosa FN. According to classification scale, leachate was classified as ‘very toxic’ (TII50 = 17). The biodegradability criterion for wastewater is the ratio of BOD5/COD, which was 0.54 in the leachate medium. The relatively higher values of ratio indicate pollution of the leachate by biodegradable matter. The microscopic analysis was conducted to study the development of activated sludge flocs and its morphology. Leachate sample was found to be biodegradable since more than 72 % COD was removed and complete degradation of nicotine was accomplished.
