Adsorption-ozonation process is one of the advanced oxidation processes for wastewater treatment, which consists of adsorption and ozonation processes. The toxic and bio-refractory pollutant p-nitrophenol (PNP) widely exists in wastewaters, such as chemicals, pesticides and dyes wastewaters. In the present study, Activated Carbon Fiber (ACF) is chosen as an adsorbent during the treatment of PNP wastewater using the adsorption-ozonation process. The effects of some operational parameters on PNP degradation, ...
