In the work described here the technical and economic feasibilities of Advanced Oxidation Processes(AOPs) have been studied: Conductive-Diamond Electrochemical Oxidation, and SnO2 anode withbiological technical. The comparison was made by assessing the two technologies with real examplewastewaters polluted with actual wastes industrial cartons in area of Agadir country. That industrialwaste contains different types of organic compounds such as (starch,Paraffin, glue, caustic soda, salt,lubricants, inks, and borax). All two technologies were able to treat the wastes, but very differentresults were obtained in terms of efficiency and mineralization. Only CDEO could achieve completemineralization of the pollutants for all the wastes. However, the efficiencies were found to depend onthe concentration of pollutant (mass transfer control of the oxidation rate). Results obtained in the2 oxidation with SnO2 are lower than boron-doped diamond anodes at 60 mA/cm . The value of CODvaries between 2g / L and 3g / L, which correspond to a variation in the costs of the electrochemicaloxidation of wastewaters of operation of the cell 945DH / days to 1500 DH / days. The efficiency ofthe electrochemical process was found to depend mainly on the pollutant concentration present in thewaste and on the applied current density. The high efficiency of this technology can be explained interms of the direct electro-oxidation at the BDD surface and the oxidation carried out by hydroxylradicals and other electro-generated oxidants.
