APPARATUS FOR BIOREMEDIATION OF SOIL CONTAMINATED WITH ORGANIC COMPOUNDS

摘要

This invention relates to an apparatus for the bioremediation of soil contaminated with organic compounds, preferably meant for portable use, comprising a bioreactor tank in which the soil is placed and characterized in that the gases injected during the process by means of strong, forced aeration, having a homogeneous distribution of oxygen are recirculated, such that the tainted gas is discharged to the outside after treatment inside same apparatus. The apparatus also causes the leachates generated in sufficiently high volume to periodically recirculate in order to obtain a high humidity content and a homogeneous distribution of the humidity, the nutrients and the micro-organisms. In order to counteract resistance to oxygen diffusion owing to the soil's high humidity, high-intensity injections or recirculation are used. The combination of both types of recirculation optimizes biodegradation performance and conditions with a minimal environmental impact.
