Paper Title:
A Combined Electrocoagulation-Electrooxidation Treatment on CTMP Wastewater
  Abstract

A synergistic combination of electrocoagulation and electrooxidation was introduced for the treatment of CTMP wastewater in which most of the colloids and charged species had been removed by electrocoagulatio, then small organics could be mineralized by electrooxidation effectively.The mainly influencing factors for electrocoagulation such as electrolyte, sodium chloride dosage, voltage intensity, current intensity and reaction time were assessed. The optimum conditions were obtained, and the results showed that sodium chloride dosage of 1g/L, voltage intensity of 7.5V, current intensity of 0.6A, 60 min reaction time, its color removal rate was above 90% and CODCr removal rate was about 40%. After electrocoagulation the electrooxidation could further reduce CODCr above 80%.
