Leachate treatment facilities are designed to remove pollutants from leachate, but their effectiveness in removing emerging contaminants such as microplastics (MPs) remains uncertain. In this study, three leachate treatment facilities near M-city were selected for regular l ong-term s ampling. The goal w as t o determine w hether MPs a re c ontinuously discharged in leachate and to analyze their behavior throughout the treatment process. At Facility C in particular, a total of five samples were collected from different stages of the treatment process: raw leachate, effluents from primary and secondary sedimentation tanks, final treated leachate, and dewatered sludge cake. These samples were used to evaluate the fate and removal efficiency of MPs. Additionally, MPs concentrations were analyzed before and after rain events to assess the correlation between rainfall and MPs levels, as well as the impact of rainfall on MPs mobility in leachate.
The results of confirmed that MPs were consistently detected in both raw and treated leachate each month. MPs concentration decreased as the leachate underwent the treatment process. The highest MPs concentration was found in the dewatered sludge cake, suggesting that MPs likely settled and were transferred into the sludge during treatment. Despite a weak correlation between increased rainfall and higher MPs concentrations in leachate, the difference was not statistically significant.
