<p>PROBLEM TO BE SOLVED: To provide a simulation device of an activated-sludge water treating device with which an appropriate combination of biological reaction tanks, the design of the civil structure, e.g. volume of the tank, and operating condition fulfilling the requirement of target treated water is supported. SOLUTION: The same water-quality item of sewage for each of the sewage treating stages in the activated-sludge water treating device is obtained by simulation operation and indicated on an indicator in order of the stages by this invention. Namely, the same water-quality item of the inflow sewage and treated water and the sewage in each of the sewage treating stages in the activated-sludge water treating device is obtained by simulation operation and indicated on the indicator in the flowing order of sewage.</p> |
