摘要: The biochemical oxygen demand (BOD) of aqueous liquids containing organic matter is determined. A microorganism culture aerated to exhaust the available microorganisms. An liquid test sample added exhausted measure amount consumed by determination determined in as little 20 minutes. apparatus provided for determining BOD comprising a magnetic stirrer, an aerating instrument, dissolved oxygen/temperature sensor, tubing pumps and quick (QBOD) bottle. may be automatically calculated using apparatus.
