dc.description.abstractWastewater reuse is considered globally as a very important element of sustainable water management. Conventional wastewater treatment methods are not effective for the degradation of toxic trace organic compounds, so advanced treatment processes are sometimes needed when the wastewater effluent is likely to be reused or discharged to a river. The existence of toxic trace organic contaminants in the effluent wastewaters has increased awareness of environmental effects and potential concerns for human health. In this work, the advanced oxidation process (AOP) under solar irradiation was successfully used to decompose p-cresol, which is considered to be a toxic trace organic contaminant, from wastewater effluents. The objective of this thesis was to investigate the effect of the EfOM on the overall degradation of the trace organic matter and bulk organic matter through the formation of reactive oxygen species (ROS) and photoexcited dissolved organic matter intermediates (DOM*) under sunlight irradiation. Solar photolysis experiments were conducted to determine the degradation of p-cresol at different conditions, including varying the secondary effluent WW concentration, the initial concentration of the target compound and light intensity. Results from these experiments were reported and discussed to get the optimal treatment processes.
