DEVELOPMENT OF ELECTRO-FENTON TECHNIQUE AND THE STUDY ON BACTERIAL INACTIVATION IN SEAWATER BY NB-TA/ACF BIPOLAR ELECTRO-FENTON
Journal Title: Open Journal of Chemical Engineering (OJCE) - Year 2018, Vol 1, Issue 1
Abstract
Electro-Fenton technology is a new type of electrochemical advanced oxidation technology in water treatment in recent years. The treatment for microorganisms, such as bacteria, has been the main problem of discharge of ballast water. In this paper, a new type of bipolar electro-Fenton of Nb-Ta/ACF was proposed, and the inactivation for bacteria by the bipolar electro-Fenton technology was studied. The results showed that the Nb-Ta/ACF bipolar electro-Fenton technique is effective for the inactivation for bacteria, and the sterilization efficiency could reach up 99%. Electrodes materials, operation voltage, pH and electrolytic time have influence the sterilization efficiency. In experimental range, the optimum pH was 8.17, which is the pH of raw water without adjustment. High voltage is helpful to improve the sterilization efficiency. Electrodes materials affect the sterilization efficiency by the bipolar electro-Fenton process. Anode of Nb-Ta (Niobium Tantalum) is much better than the effect of anode of Fe.
