Water treatment plant operation management support system and operation management support method

An operation management support system for a water treatment plant, the operation management support system comprising:

• an air supply pipe through which air or oxygen is delivered from an air blower;
• an air diffuser which is connected to the air supply pipe and to which the air or the oxygen is supplied from the air supply pipe;
• a treatment water tank in which the air diffuser is arranged in treatment water and the air or the oxygen is released into the water from the air diffuser;
• a vibration information collection device that collects vibration information produced by bubbles which are formed in the water by the air or the oxygen, the air or the oxygen being released from the air diffuser, in the treatment water tank;
• and
• an information processing device which performs predetermined information processing for the vibration information collected by the vibration information collection device, wherein
• the information processing device includes
• a vibration information obtainment unit which obtains the vibration information from the vibration information collection device and performs predetermined transform processing for the obtained vibration information,
• a determination algorithm execution unit which executes processing based on a predetermined determination algorithm for the vibration information for which the predetermined transform processing is performed by the vibration information obtainment unit,
• a vibration information determination unit which makes a determination about an abnormality of the air diffuser based on an output result output from the determination algorithm execution unit, and
• a determination result notification unit which notifies a result of a determination by the vibration information determination unit.
