Abstract

BOD (Biochemical Oxygen Demand) is utilized widely as an index of water quality. However, nitrification is a cause of significant errors in measuring BOD, particularly when a large population of nitrifying organisms are existing in water such as effluents from biological treatment plants. In this case, the use of a nitrification inhibitor is recommended, but it is not used commonly. In order to investigate the amount of nitrogenous oxygen demand (NOD) which is caused by nitrification, BOD with and without inhibitor was measured as samples in the Kitakyushu area. About 70 percent of BOD from the effluents of biological treatment plants was NOD. In the case of influent of biological treatment plant and river waters, 0-39 percent of NOD was contained in BOD.

摘要

生化需氧量（BOD）被广泛用作水质指标。然而，硝化作用是测量BOD时产生重大误差的一个原因，特别是当水中存在大量硝化生物时，如生物处理厂的废水。在这种情况下，建议使用硝化抑制剂，但它并不常用。为了调查由硝化作用引起的含氮需氧量（NOD）的量，在北九州市地区测量了添加和未添加抑制剂的BOD作为样本。生物处理厂废水中约70%的BOD是NOD。在生物处理厂的进水和河水的情况下，BOD中含有0-39%的NOD。
