A Highly Effective Photochemical System for Complex Treatment of Heavily Contaminated Wastewaters

Popis výsledku v původním jazyce

Significant effort has been committed to the research and development of many advanced oxidation processes including photocatalytic oxidations with titanium dioxide or the H2O2/Fe2+(Fe3+)/UV process. Here we report on the development of the photochemicalsystem for complex treatment of heavily contaminated wastewaters based on the utilization of UV-C light and hydrogen peroxide. Special focus was given to the technology employed, first addressing the reactor design, then the process control and finallythe process performance optimization. Effects of process parameters were studied with 4-chlorophenol (4CP) as common model compound and verification of this technology is shown on the treatment of real contaminated water. Among the most influential parameters were the 4CP concentration, reaction mixture volume, concentration of hydrogen peroxide, and the irradiation intensity. On the contrary mode of hydrogen peroxide dosing and the flow rate were found insignificant.
