Autotrophic Ammonium Removal Process

The removal of nitrogen from wastewater has become an important part of the overall treatment process due to the significant impact of nitrogen compounds on the environment and the more stringent discharge standards. Since the anammox has discovered, it has been taken much concern from the biotechnologists and engineers who want to remove nitrogen in wastewater. Because the process doesn’t need additional carbon source in denitrification, don’t need aeration for nitrification, and produces less waste sludge etc. compare to conventional nitrification/denitrification process in WWTP. This research is also a kind of application research of anammox process. The goal of this research is to establish Autotrophic Ammonium Removal Process of a fixed-bed column reactor. The reactor set up up-flow type. The microbial dynamics of the biofilm within the reactor by molecular technologies and various items such as pH, O2 concentration and the ratio of NH4/NO2 etc. are being monitored to increase the performance.
