摘要：
A slaughterhouse wastewater (SHW) with high organic load (20240 mg/L COD) was treated by photolysis (PHO) and heterogeneous solar photo-Fenton (HSPF). Direct photolysis showed to be the best treatment at the pH of the sample (6.4), COD, color, total fecal coliforms, sulfates and phosphates were removed in 81.3, 86.5, 99.0, 91.7 and 33.5% respectively. The HSPF treatment was performed using electrochemically modified zeolites as catalyst, the removal efficiencies were 58-71% for COD and 92-95% for color at pH 6.4. Finally, a coupled system (PHO- HSPF) achieved efficiencies of 84.5-91.6% and 95.8-99.9% for COD and color respectively.
