BIODEGRADATION PATHWAY PREDICTION OF POPS(PERSISTENT ORGANIC POLLUTANTS) AND BIOBARRIERTREATMENT

摘要

In this paper, the biodegradation pathway of Dieldrin is simulated using an expert system. Thisinsecticide is included in the Stockholm Convention, signed and ratified by Colombian government in 2008, and it isconsidered one of the most harmful humanmadecompounds. For this model contaminant a complete metabolicbiodegradation sequence was built and a simulationbasedstrategy was formulated for its biodegradation in apractical case.According to the simulated metabolic pathway, a sequential aerobicanaerobicaerobicreactor would be the bestchoice to achieve complete biodegradation. Using these results, the authors propose an innovative system for thebiological treatment of POPs? this system was called BioReactivePermeable Barrier (BioBarrier). In this work adescription of the main and fundamentals aspects of BioBarrier system is also included, showing a new and potentialpossibility for the biotreatmentof hazardous pollutants.
