PROBLEM TO BE SOLVED: To provide a quality control method of water in a polluted water tank or a swimming water tank for efficiently performing the quality control of water by controlling the water supply and discharge amounts of the polluted water tank or the swimming water tank so as to be capable of properly reducing the degree of turbidity in the polluted water tank or the swimming water tank within a predetermined time, and a water-quality control system.;SOLUTION: In a swimming water circulation system for discharging the swimming water in the swimming water tank 1 producing turbidity by floating particles as sucked wastewater or flooding water and filtering the discharged swimming water by a filter 4 to again supply filtered water to the swimming water tank, the movement of swimming water containing floating particles when the swimming water circulation system is operated for a predetermined time within 24 hr is simulated by the analysis of a numerical value in order to reduce the turbidity of swimming water, and a water supply amount, a sucked wastewater amount and a flooding water amount are calculated so that the turbidity of swimming water becomes a set turbidity degree or below by discharging floating particles from the swimming water tank along with swimming water to control the swimming water circulating system on the basis of these water amounts.;COPYRIGHT: (C)2008,JPO&INPIT
