Traitement des polluants organiques persistants par décharges à barrières diélectriques (DBD) et par décharges glissantes (Glidarc)

Abstract : This work reports on using plasma process that produces in situ highly oxidizing species able to degrade organic compounds to study the treatment of organic pollutants. By this way, we studied the degradation of some organic pollutant by gliding arc plasma (Glidarc) and by dielectrics barriers discharges (DBD). The first part was dedicated to the degradation of mercaptans by Glidarc with an optimization of different experimental parameters to finish with and application of this process to the decontamination of an industrial effluent rich in mercaptans. A second part was devoted to the study of the degradation of methyl red by Glidarc firstly then by DBD. After optimization of various experimental parameters, a comparison between the two techniques was performed. The third part presented the results obtained from the treatment of triphenylphosphine sulfide present in an organic phase on top of a water phase by Glidarc. A final section was devoted to the modeling of the degradation of methyl red by a new considered horizontal Glidarc reactor. Results show the efficiency of plasma process, DBD and Glidarc, for the treatment and degradation of organic pollutants. So plasma can be considered as an alternative technique compared to other conventional and usual remediation techniques as it has the advantage of being environmentally friendly, economical and efficient.
