This invention belongs to the field of wastewater treatment technology, specifically relating to a method and apparatus for removing COD from high-salt, high-organic-content wastewater. The removal method employs two organic matter retention membranes connected in series to treat the high-salt, high-organic-content wastewater. By controlling appropriate process conditions, these organic matter retention membranes primarily retain organic matter while retaining as little salt as possible, ensuring stable operation of subsequent processes or achieving compliant wastewater discharge. Furthermore, the concentrate obtained after treatment by each organic matter retention membrane is returned in a specific proportion to the inlet of the membrane that produced the concentrate, thereby ensuring efficient and stable membrane operation, improving system recovery rate, and extending membrane lifespan. This invention achieves COD removal from high-salt, high-organic-content wastewater using only a single process, exhibiting high removal rate, good decolorization effect, and high recovery rate. It significantly shortens the process flow and is characterized by being green, efficient, energy-saving, environmentally friendly, and highly reliable.
