Partial nitrification—operational parameters and microorganisms involved

摘要: Nitrite is a common intermediate in at least three different oxidative or reductive biochemical pathways that occur nature (nitrification, denitrification and dissimilatory assimilatory nitrate reduction). accumulation partial nitrification has been reported literature for decades. In engineered systems, of interest as it offers cost savings aeration well the form lesser need addition organic carbon compared to conventional denitrification. A broad range operating parameters factors reviewed this paper which are essential achieving nitrification. Of these, pH, dissolved oxygen (DO), temperature, free ammonia (FA) nitrous acid concentrations, inhibitory compounds important
