WATER QUALITY MANAGEMENT DEVICE, WATER TREATMENT SYSTEM, WATER QUALITY MANAGEMENT METHOD, AND PROGRAM FOR OPTIMIZING WATER TREATMENT SYSTEM
First Claim
1. A water quality management device which manages a circulating water system of a plant including a circulation line through which circulating water is circulated, a supply line which supplies makeup water to the circulation line, a discharge line which discharges the circulating water from the circulation line, and a chemical injection line which injects a chemical to the circulation line, the water quality management device comprising:
- a determining unit configured to determine an amount of concentration control associated with a concentration rate of the circulating water system;
an acquisition unit configured to acquire plant data on the plant used by the determining unit to determine the amount of concentration control;
a relational storage unit configured to store one or more inference rules associating a condition of the plant data and an amount of concentration control of when the condition is satisfied with each other;
an input unit configured to receive an input of an amount of concentration control which satisfies a predetermined limit value and is specified based on the plant data acquired by the acquisition unit; and
an updating unit configured to generate a new inference rule based on the amount of concentration control input to the input unit and record the new inference rule on the relational storage unit,wherein the determining unit determines an amount of concentration control based on the plant data acquired by the acquisition unit and the inference rule stored in the relational storage unit.
