PURPOSE: A zero discharge wastewater treatment method and a system for the same are provided to conserve energy cost needed for generating brown gas and to remove non-degradable materials from wastewater. CONSTITUTION: A zero discharge wastewater treatment method includes the following steps: wastewater from a wastewater tank(40) is liquid-sprayed into a combustion furnace(10) equipped with a torch and a reactor(19); the reactor is heated by the flame of the torch, and the wastewater through the combustion furnace is combusted to be incinerated; waste heat from the wastewater incineration process is used for heating the wastewater from the waste tank; and vapor from the wastewater heating operation of the wastewater tank is introduced into the combustion furnace. The torch mixes brown gas and fossil fuel for flame. [Reference numerals] (60) Stack; (AA) Vapor; (BB,CC) Wastewater; (DD) Electricity |
