Study on the treatment of landfill leachate using FeSO4.7H2O/NaOCl for Reactive Oxygen Species generation

Tóm tắt

Leachate treatment is an urgent issue due to the high concentration of pollutants, which are difficult to treat using traditional technologies. Recently, reactive oxygen species (ROS) generating systems have been studied for potential applications. This paper presents the research results on the leachate treatment capability of the FeSO₄·7H₂O/NaOCl system. The study shows that the FeSO₄·7H₂O/NaOCl ROS-generating system is effective in treating leachate, reducing COD by nearly 80%, TDS by 71.2%, and changing the water color from dark black to light brown, while eliminating foul odors after 30 minutes of reaction at room temperature, pH = 6.9.
