Treatment of Wastewaters Generated by Surfactant-Enhanced Washing of Soils in an Aerobic Biofilter Inoculated with a Consortium of Hydrocarbon Degraders

摘要

Aims: The aims of this work were 1) To evaluate the performance of a submerged biofiltration system for the treatment of a surfactant-enriched wastewater that had been generated by a soil washing process. 2) To evaluate the effect of the flux and organic load over the performance of the system. 3) To determine the microbial evolution as an effect of the flux at different lengths of the biofilter by using a denaturing gradient gel electrophoresis (DGGE) analysis.
