Studies on Polluted Soil Aeration Systems to Improve Efficiency of Soil Remediation Using Biopile Technology

摘要

Recent researches have emphasized the difficulty of biodegradation in organic compounds. To biologically remove these organic compounds some complex problems should be resolved: the need for direct contact between products added as stimuli in the biodegradation process and the polluted soil, as well as the thorough examination of the biomass development and the transformation of pollutant compounds, taking into account the products resulted after the decontamination process. In order to design aeration systems to achieve a maximum level of biodegradation through biopile technology simulations of this system and further experiments must be carried out to explore in detail the method of aeration and to develop criteria for making such systems. Natural and forced aeration (blowing or extracting air through pipes) can be introduced to improve soil ventilation to assure the oxygen supply needed for the bioreactions taking place in the pile of polluted soil.
