| description | There are disclosed a continuous, quick measurement method of BOD and an apparatus therefor. It comprises a sample tank in which a sample is prepared suitably for the measurement, a reactor in which microorganisms maintain their activity, a medium reservoir which contains nutrients for the growth of the microorganisms, pumps for transferring liquids, and a microprocessor which controls the operation of all means including a magnetic stirrer for mixing the liquid in the reactor and diagnoses of the apparatus itself. Using the apparatus, the method comprises a continuous culture stage, an endogenous respiration stage, a endogenous respiration rate-measuring stage, a sample feeding stage and a BODq measuring stage. The apparatus can detect BOD in one hour and is very low in error rate. Further, because microorganisms can be continuously cultured, the apparatus is semi-permanent, easy to manage, low in cost and suitable to be operated at treatment site. |
