| الوصف: | Ozone (O3) is a potent oxidizing agent that breaks down refractory organic contaminants (ROCs) into smaller, less hazardous molecules. In heterogeneous catalytic ozonation (HCO), O3 is injected into the wastewater stream as a gas or as O3-enriched air. A solid catalyst improves ozonation efficiency by boosting O3 breakdown and the production of reactive oxygen species (ROS) capable of oxidizing ROCs. Metal oxides (Me Os) are the often used catalysts. However, the kind of HCO catalyst used and how it reacts with O3 determine how much ROS is produced. The production of ROS is encouraged by various HCO catalysts via various mechanisms, which may affect the HCO process's efficiency and selectivity. The kinds, mechanisms, and characteristics of the various HCO catalysts used are thoroughly examined in this study to provide a deeper understanding of the HCO process. In addition, parameters that need to be adjusted to improve degradation efficiency-such as pH and temperature are covered. The study ultimately expands on already published research to identify a variety of HCO applications while considering the viability of HCO in the form of pilot-scale and full-scale implementations, as well as real-world performance. HCO catalysts' challenges and promises for future water treatment are assessed. The goal of the current review is to provide academics and specialists with an overview of the application of HCO for ROC degradation. |
