<p><P>PROBLEM TO BE SOLVED: To provide anaerobic treatment equipment which can accurately specify causes that a normal operation is not performed in a short period of time, and to provide its monitoring method. <P>SOLUTION: A monitoring method in anaerobic treatment equipment 10 having a reaction vessel 2 which performs anaerobic treatment of organic waste water to generate gas includes the steps of: decreasing a flow rate when an organic substance concentration from the reaction vessel 2 becomes not less than a reference value; as a result, discriminating whether a removal base gas incidence calculated on the basis of the flow rate, an inflow organic substance concentration, a flowing-out organic substance concentration, and an amount of gas generation of the organic waste water is the normal value, when the flowing-out organic substance concentration continues being not less than the reference value. The causes that the normal operation of the anaerobic treatment equipment 10 is not performed can be specified by adjusting the flow rate of organic waste water according to the flowing-out organic substance concentration measured when the flowing-out organic substance concentration becomes not less than the reference value about inflow of high concentration organic waste water, and by calculating the removal base gas incidence about the sludge. <P>COPYRIGHT: (C)2004,JPO</p> |
