外文摘要：Increasingly stringent nutrient limits on wastewater treatment plant discharge are requiring abetter understanding of treatment technologies for phosphorus and nitrogen removal。 The City ofCoeur d’Alene Wastewater Treatment Plant’s initial interest in a tertiary membrane filtration(TMF) process was to meet ultra-low effluent total phosphorus (TP) concentrations of less than0。050 mg/L TP。 The City decided to conduct a two-year demonstration pilot program todetermine additional valuable information (i。e。 phosphorus removal reliability， designparameters， operating strategies， etc。) about the TMF system。 Results show that the TMF systemproduced effluent quality of less than 0。050 mg/L TP on a monthly average basis。 Whileoperating with a solids inventory of approximately 2，000 mg/L TSS， the TMF system was alsonitrified， reducing ammonia levels to less than 3。0 mg/L NH_4-N on a monthly average basis。
