Revolutionizing Sports Field Maintenance: A Novel Bionic System for Soil Remediation Using Microwave Thermal Desorption and Microwave Absorbents

Abstract

Background: Maintaining the health and safety of sports fields is crucial for athlete performance and environmental sustainability. This study explores a novel bionic system using microwave thermal desorption enhanced by microwave absorbents to treat insulating oil-contaminated soils, commonly found in areas surrounding sports facilities due to machinery use and maintenance activities. Methods: We conducted desorption experiments using a microwave-thermogravimetric reaction device on oil-contaminated soils, comparing the efficacy of treatments with and without microwave absorbents. The experiments measured the removal rates of contamination at various temperatures and microwave power settings, aiming to optimize the energy efficiency and effectiveness of the remediation process. Results: The removal rate for the group without absorbent reached 99.1% at 450 ℃, while the introduction of a microwave absorbent increased the removal efficiency to 99.6% at a reduced temperature of 400 ℃. At microwave power settings of 1000W and 1200W, the removal rates were 99.3% and 99.5%, respectively, with corresponding energy consumptions of 0.211kJ and 0.255kJ. The addition of microwave absorbent significantly reduced the energy required for desorption, making the 1000W setting the most economical and effective for soil treatment. Conclusion: The application of a microwave thermal desorption system with added microwave absorbent offers a promising method for the remediation of contaminated soils in sports field environments. This technique not only enhances the removal efficiency of pollutants at lower temperatures and reduced energy costs but also supports the sustainability and safety of sports facilities. Further research is suggested to fully integrate this technology into routine maintenance protocols for athletic fields, ensuring optimal conditions for both the environment and athletic performance.
