<p><P>PROBLEM TO BE SOLVED: To solve the following problem: in a monitoring method for an aeration tank where the oxygen consumption rates of sludge are measured at a plurality of points along the down flow direction of the aeration tank and the time change of the consumption rates are displayed, it is difficult to visually grasp the time change of a processing state of the aeration tank because a plurality of curves coexist on a graph. <P>SOLUTION: A plurality of the oxygen consumption rates are integrated with respect to a volume to a measuring position to plot an oxygen consumption rate in the whole aeration tank in a curve on the graph, thereby enabling a visual grasp of a load state of the aeration tank. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
