Abstract
A wastewater treatment apparatus and method with stair-like heat treatment tanks for performing a breakdown process are disclosed, in which the apparatus comprises: a mixing tank, for evenly mixing wastewater with reaction agents and thus forming a mixed solution; a plurality of heat treatment tanks, for enabling the mixed solution to circulate therein while being heating for a period of time so as to perform an organic destruction process upon the mixed solution and thus cause a discharging liquid to be formed; a heat exchanger, for enabling a heat exchanging process between the discharging liquid and the mixed solution to be performed therein; a condensation tank, for receiving and cooling the discharging liquid; a water purifier, for purifying and thus separating the discharging water into a cleaned water and a concentrated liquid for outputting; an agent recycling unit, for electrolyzing the concentrated liquid so as to recycle the reaction agents.
