Biodenitrification of Industrial Wastewater

摘要

The Feed Materials Production Center (FMPC), a US Department of Energy facility at Fernald, Ohio, is constructing a fluidized-bed biodenitrification plant based on pilot work conducted at the Oak Ridge National Laboratory (ORNL) in the late 1970s and early 1980s. This plant is designed to treat approximately 600 to 800 L/min of wastewater having a nitrate concentration as high as 10 g/L. The effluent is to contain less than 0.1 g/L of nitrate. Since this new facility is an extrapolation of the ORNL work to significantly larger scale equipment and to actual rather than synthetic wastewater, design verification studies have been performed to reduce uncertainties in the scaleup. The results of these studies are summarized in this report. 7 refs., 1 fig. (ERA citation 12:028351)
