CHEMICAL INJECTION CONTROL DEVICE, DRUG MANAGEMENT DEVICE, WATER TREATMENT SYSTEM, CHEMICAL INJECTION CONTROL METHOD, AND PROGRAM

摘要

To provide a chemical injection control device, a chemical management device, a water treatment system, a chemical injection control method, and a program for optimizing an injection amount of drug into a water system.SOLUTION: A chemical injection control device 110 includes a determination unit that determines an injection amount of each of a plurality of drugs having different components into the water system on the basis of the water quality of the water system. The determination unit is configured to determine the injection amount of each of the plurality of drugs or determine the injection amount of each of the plurality of drugs so as to reduce the cost on the basis of the constraint including the combination of prohibited drugs.SELECTED DRAWING: Figure 1
