Popis: International audience; The study evaluates the feasibility of the degradation of thirteen pesticides by an activated sludge aerobic treatment, used for the purification of wastewater effluents produced from a winemaking process. Chemical analyses were used to determine the capacity of the treatment to eliminate the implied pollution hazard. The results show that the biological treatment of such pesticides by activated sludge is possible if a minimum adaptation period of approximately 8 days is applied. System stability is reached in 30 days. The related degradation of twelve pesticides was 97%, the exception being anilinopyrimidin. However, the sludge biomass is dispersed (the pesticides destroyed the biomass flocs) and it was necessary to add a flocculation stage to concentrate and remove the free micro-organisms by using sedimentation.
