Abstract

The biochemical oxygen demand (BOD) test is widely used to determine the pollution strength of water, to evaluate the performance of wastewater treatment plants and to judge compliance with discharge permits. However, nitrification is a cause of significant errors in measuring BOD, particularly when a large population of nitrifying organisms is existing in water such as effluents from biological treatment plants. In order to investigate the amount of nitrogenous oxygen demand (NOD), BOD with and without inhibitor was measured as samples in the biological treatment plants. About 81% of effluent BOD from the biological treatment plant used in this experiment was comprised of NOD. In the case of influents, the NOD accounted for about 9% of BOD. The inhibited 5-day BOD (Carbonaceous BOD) test must be considered in evaluating the performance of wastewater treatment plant and judging compliance with discharge permit limitations.
