1. A waste water incineration method comprising:
(S10) supplying waste water to an evaporator to evaporate the waste water;
(S20) supplying an evaporator top discharge stream discharged from the evaporator to an incinerator to incinerate the evaporator top discharge stream;
(S30) mixing a first incinerator discharge stream discharged from the incinerator and a second incinerator discharge stream discharged from the incinerator to form a mixed discharge stream; and
(S40) heat-exchanging the mixed discharge stream and a fresh air stream in a first heat exchanger,
wherein the mixed discharge stream which has passed through the first heat exchanger is heat-exchanged in a second heat exchanger and then discharged to the atmosphere, and
wherein a temperature of the first incinerator discharge stream is higher than a temperature of the second incinerator discharge stream.
