ABSTRACT:
The present invention provides an evaporative concentration apparatus for waste water having an evaporating vessel 2 for evaporatively concentrating waste water and a heater 3 for circularly heating an in-vessel liquid in the evaporating vessel 2, in which the whole or part of thermal energy of generated steam 6 discharged from the evaporating vessel 2 is recovered by an absorption heat pump 29, and the thermal energy is supplied to the heater 3. According to the present invention, evaporative concentration can be effected efficiently in the evaporating vessel by effectively utilizing the thermal energy of generated steam, and also the operation of evaporative concentration apparatus can be performed stably by stably securing heating steam quantity.
