Basic Research on Nitrogen Removal in Aerobic Treatment System (I)

In this paper we deal with the denitrification in aerobic treatment system. We called this phenomena “Aerobic denitrification” Recently, basic research on this aerobic denitrification is seldom found, although its practical applications have been rather extensively studied. Hence, we have conducted experimental research in order to obtain basic data to establish a clear phenomena of aerobic denitrification. As the results, basic research on the aerobic denitrification of night soil was conducted to investigate the optimal condion of the denitrification and the removal rate of nitrogen. The experimental results showed that about 80% of nitrigen were removed by aerobic denitrification even in the laboratory conditions.
