Abstract

Abstract:

Solar interfacial evaporation has attracted significant attention as an efficient wastewater treatment technology. By optimizing the materials and structural design of solar evaporators, the evaporation performance can be enhanced obviously. However, this technology still faces serious challenges when treating complex composition and highly concentrated pollutant wastewater. This review explored the application strategies of solar interfacial evaporation technology for removing conventional and emerging water pollutants, including metal ions, volatile organic compounds, dyes, microplastics, and oils. Additionally, an in-depth analysis of the key challenges in wastewater treatment using this technology was provided, and corresponding solutions and future research directions were proposed.

Key words: solar interfacial evaporation, wastewater treatment, desalination, antifouling, zero liquid discharge
