摘要：

This study is based on the investigation of performance of associated wastewater treatments of coagulation-flocculation/adsorption (CF-ADS) and coagulation-flocculation/ozonation (CF-OZ) for the removal of pollutants from tannery wastewater. The chemical dosage was optimized and the use of waste from the tannery process was tested as a low-cost alternative adsorbent for wastewater treatment plants. For the CF-ADS the removal of TOC, COD, Na+ and color were 50.04%, 53.13%, 17.05% and 61.13%, respectively, and for the CF-OZ the removal were 46.50%, 56.25%, 11.10% and 85.34%. Also, BOD/COD and COD/TOC ratios were studied to verify the oxidation efficiency of the wastewater.
