RBC nitrification of high ammonia leachates

摘要

AbstractA study was conducted on treating a simulated leachate that contained high concentrations of ammonia‐nitrogen ranging between 20 and 1000 mg/L. A pilot sized rotating biological contractor (RBC) was used to treat a surrogate leachate composed of primary effluent that was adjusted with glucose and ammonium chloride to achieve various concentrations of dissolved organic carbon (DOC) and ammonia‐nitrogen. Experiments were conducted to determine:The rate of ammonia conversionThe drop in pH at high ammonia concentrationsThe effect of low pH on ammonia conversionThe effect of high ammonia levels (1000 mg/L) on ammonia conversionThe effect of temperature on the reaction rate constant The results from these experiments and the applicability of a RBC to treat leachates containing high concentrations of ammonia‐nitrogen are rep
