Abstract

The Electrocoagulation and Ultrafiltration integrated process was proposed to treat bathing wastewater. Influences of electrode substance , current density , electrolytic time and conductivity on removal efficiencies of turbidity and COD were investigated . The cleaning cycle and the cleaning scheme were determined. The results show that Al electrode is preferable to Fe electrode for the treatment effect , the removal efficiencies of COD and turbidity were more than 85% and 95% respectively. The membrane cleaning cycle is twelve days. The membrane flux is recovered to 100% with chemical cleaning and hydraulic rinse.
