To provide an evaporation concentration equipment which simply and easily controls the temperature of a liquid to be concentrated and easily and efficiently controls the concentration ratio of a liquid to be treated at a low cost.
In evaporating water contained in a liquid to be treated by directly bringing the liquid to be treated into contact with an exhaust gas, the temperature of the liquid is controlled by enhancing the drying capability of the exhaust gas by mixing it with air according to the temperature of the liquid. After starting the equipment, a predetermined concentration lower than a predetermined concentrated concentration of the concentrated liquid is detected; then, the operation of a concentrating pump/the discharge of the concentrated liquid are carried out so that the ratio of the amount of a supplied raw liquid to the amount of the discharged concentrated liquid corresponds to the concentration ratio; thus, the concentration is controlled so as to converge to a specified concentration with time.
