The aim of this work is to assess the effectiveness of the process of removing from the wastewater two commonly occurring in the aquatic environment anthropogenic micro-pollutants, i.e. sulfamethoxazole (SMX) and diclofenac (DCF) using constructed wetlands combined with solar light induced processes (assisted by TiO ). The research has shown that the removal of these compounds in the constructed wetlands is an effective process, however, it is not possible to completely remove the tested compounds from wastewater. In addition, it has been shown that plants occurring in constructed wetlands have a positive impact on the processes efficiency. The combination of constructed wetland with solar-light induced processes allows for complete elimination of DCF from wastewater and over 90% removal of SMX. In the work, an attempt of the identification of the main transformation products of the tested compounds was performed. It was observed that the main transformations of the studied substances are hydroxylation and methylation, which can occur simultaneously in constructed wetlands.
