SYSTEM AND METHOD FOR REMOVING MICROPOLLUTANTS FROM WASTEWATER

摘要

The invention is directed to a device adapted for wastewater treatment, said wastewater comprising at least one sort of micropollutant. Said device comprises a column 2 and a backwashing system in fluid connection with said column. The column comprises an inlet 4 and an outlet 6, said inlet being upstream to said outlet. The column also comprises a zone which comprises bacteriologically activated carbon 8 which is downstream to said inlet, said zone being divided in subzones A, B and C. In addition, the column comprises a backwashing space 10, being downstream to said zone comprising bacteriologically activated carbon. Said device is remarkable in that the bacteriologically activated carbon of subzone A comprises starving micro-organisms, the bacteriologically activated carbon of subzone B comprises micro-organisms fed through a first feeding system 14 and the bacteriologically activated carbon of subzone C comprises micro-organisms fed through a second feeding system 16.
