This invention relates to a resource-recycling type method and apparatus for treating industrial wastewater using an oxidizing agent produced from wastewater, wherein, in the treatment of industrial wastewater containing nitrogen compounds and refractory COD-causing pollutants, an oxidizing agent is autonomously produced using ammonia gas stripped from wastewater and is then added back to the wastewater, thus economically treating the wastewater without the need to purchase an expensive oxidizing agent. This wastewater treatment method, suitable for use in decreasing amounts of nitrogen pollutants (T-N), including ethanolamine compounds and ammonia nitrogen (NH&#x2014;N), and refractory COD-causing pollutants in industrial wastewater, includes: stripping ammonia from raw wastewater, producing an oxidizing agent via addition of sulfuric acid to the stripped ammonia, electrolysis and addition of sodium hydroxide, and performing chemical treatment by adding the produced oxidizing agent back to the raw wastewater from which ammonia was stripped, thus removing the nitrogen pollutants (T-N) and the refractory COD-causing pollutants, and the apparatus used to perform the wastewater treatment method is also provided.
