Modeling the Fenton depuration of the effluent from a slaughterhouse based on design of experiments

摘要

In an effort to improve the quality of treated water, the implementation of a new technology referred to as Advanced Oxidation Processes (AOP) is being examined, either alone or in combination with other processes. When working with real conditions there are sometimes changes which involve adjustments of the process, and it is easier to perform such adjustments when it has a reliable mathematical model. The studied scaled design referred to as Fenton treatment, involving the use of a central-composite design (quadratic model) which was tested on the effluent discharge of a slaughterhouse. As a result of our treatability study, we experienced removal efficiencies based on chemical oxygen demand (COD) greater than 85%, while ascertaining that removal process was the result of chemical oxidation and coagulation.
