摘要：
A water-saturated biological denitrification system was employed to remove selected pesticides and nitrate from drinking waters. In the study, approximately 99% nitrate removal was observed, but most of the samples included nitrite. Up to 95% removal of pesticides was also observed. The lowest removal efficiency of nitrate (63%) was observed when the temperature dropped sharply from 18 T to 14 T. Despite such oscillations, high removal efficiencies for trifluralin, fenitrothion and endosulfan (alpha+beta) were observed and the highest nitrite concentration was 16 mg/l in the effluent of the reactor.
