摘要：

PHOTOLYSIS AND UV/H2O2 TREATMENT OF A SYNTHETIC EFFLUENT CONTAINING FOOD DYES. Food industries employ a lot of synthetic dyes in their products. Most of these dyes are very stable face to the conventional treatments. This work Studied the use of advanced oxidation process (AOP) as an alternative to the conventional ones to degrade a synthetic food effluent (photolysis and UV/H2O2 in continuous reactor). The more efficient process was the UV/H2O2 and it presented decoloration and degradation energetic efficiency values equal to 30.775 kWh m(-3) and 269.909 kWh m(-3), respectively. The color reduction was 96.4% and COD decrease was 38.56%.
