The coupling of conventional elastic filler and solid carbon source of Phragmites communis (P. communis) as the biofilm support was applied in a biofilm system for treating polluted source water containing nitrogen and trace endocrine-disrupting pesticides (cypermethrin and chlorpyrifos). Results showed that removal efficiencies of TN and EDPs were improved with addition of 3.6 kg P. communis/m(3) in the biofilm system. Meanwhile, the uniform distribution of P. communis favored simultaneously nitrogen and organics removal but not to trace EDPs compared with non-uniform distribution of P. communis. The biofilm on elastic filler was mainly responsible for the nitrification with NH4+-N oxidation efficiency of 82.9 +/- 1.5%. Poor nitrification with NH4+-N oxidation efficiency of 36.3 +/- 6.1% but effective denitrification with a TN removal efficiency of 56.5 +/- 2.0% were obtained by the biofilm on P. communis. Cypermethrin was mainly removed via adsorption and microbial degradation, and chlorpyrifos removal mostly depended on the microbial degradation in biofilm system. (C) 2015 Elsevier Ltd.
