摘要： A completely biological method for removing a first group of micropollutants of pharmaceutical origin and a second group of micropollutants of pharmaceutical origin from raw wastewater includes: providing a first buffer tank upstream of a bioreactor; providing a moving bed membrane bioreactor (MB-MBR) for developing biomass growth both on a fixed support and in suspension in a form of flocs, and on mobile supports, the bioreactor obtaining an effluent with a COD concentration of organic matter of less than 50 mg l−1 and a total nitrogen concentration of less than 15 mg l−1; providing a biofiltration tank, separate from the first buffer tank of the bioreactor, that includes one or more biologically activated carbon (BAC) columns containing activated carbon; supplying the first buffer tank upstream of the bioreactor with raw wastewater containing micropollutants of pharmaceutical origin; pretreating the wastewater by passing the wastewater through a fine mesh sieve.
