Abstract

PURPOSE:To easily and quickly decide whether the biological treatment of target liquid is possible or not by immersing a microbe electrode comprising combining a microbe membrane and a dissolved oxygen electrode into the target liquid and detecting the decreasing mode of the dissolved oxygen current of that time. CONSTITUTION:The microbe electrode 1 combining a microbe membrane and a dissolved oxygen electrode is inserted into the liquid in a beaker 2, and the output current of that time is amplified by an amplifier 3 and is recorded in a recorder 4. The beaker 2 is put into a thermostatic water bath 5. Standard liquid saturated with dissolved oxygen is put into the beaker 2. The electrode 1 is inserted into this standard liquid and after the output current of the electrode 1 goes constant, the target liquid in the state saturated with dissolved oxygen is put into the beaker 2. In the beaker 2, it is stirred by a stirrer 6, and the electrode 1 is inserted thereon, the output current whetherof is recorded in a recorder 4.
