OPERATION MANAGEMENT SYSTEM FOR WASTEWATER TREATMENT FACILITY

摘要

This invention relates to an operation management system, a diagnostic method, and an operation management method for a wastewater treatment facility which uses activated sludge. The operation management system for a wastewater treatment facility includes: a storage means for storing a reference value for each index of a plurality of indexes indicating a state of an aeration tank; an input means for inputting a measured value of the index; a comparison means for comparing the input measured value with the reference value for each index, and categorizing each measured value as one of being within a reference value range, over the reference value, or less than the reference value; a storage means for storing diagnostic patterns, in which the diagnostic patterns are classified according to a combination of categories of: within the reference value range, over the reference value, or less than the reference value for each index, using the reference value as a reference; a checking means for checking a combination of categories of each index of the measured values against a combination of categories of each index of the diagnostic patterns, and extracting a diagnostic pattern which the combination of categories has matched; and a display means for displaying the diagnostic pattern which the combination of categories has matched.
