PROBLEM TO BE SOLVED: To provide a wastewater treatment apparatus capable of avoiding or suppressing adverse influences of salt.SOLUTION: A wastewater treatment apparatus includes: a field desalting mechanism 2 which performs desalting treatment on wastewater 1; and an overheat steam supply mechanism 3 which applies overheat steam to the wastewater 1 on which the desalting treatment has been performed. The wastewater treatment apparatus includes the field desalting mechanism which performs desalting treatment on wastewater, such that a salt concentration in wastewater can be reduced in advance before supplying overheat steam. The wastewater treatment apparatus further includes the overheat steam supply mechanism which applies overheat steam to wastewater on which desalting treatment has been performed, such that wastewater can then be purified by thermally decomposing a dirt component (generally an organic component) in the wastewater of which the salt concentration has been reduced beforehand. |
