Abstract
The aim of the present work is to study the biodegradability enhancement of a wastewater containing a non-biodegradable compound, 4-chlorophenol (4-CP), using a so-called Advanced Oxidation Process (AOP) named Photo-Fenton (Ph-F). The location of this study is in a more complex project the aim of which is the connection of this AOP with a biological treatment. The parameters to be studied are the initial concentrations of Fe2+ and H2O2 and the operating temperature. The work was planned using an experimental design named Central Composite Design (CCD), in order to observe the effect of each factor on different responses, such as 4-CP removal, Total Organic Carbon (TOC) removal, Chemical Oxygen Demand (COD) removal, Biochemical Oxygen Demand (BOD5)/COD ratio evolution and total time until the total consumption of hydrogen peroxide. The operating conditions are optimized taking into account the operating costs. The results showed that Fe2+ and temperature do not affect the degradation and biodegradability enhancement results, but they affect significantly the time of the experiment, and consequently the operating costs.
