Abstract—To develop new ship sewage treatment method, an electrochemical treatment device combined technologies of electrocoagulation, electrolyzing and photocatalysis was utilized to treat the stimulated ship sewage. The experimental showed that through the treatment of the combined technologies, BOD5, COD, TSS and Thermotolerant Coliform was reduced significantly and based on the reasonable structure design and operational parameters, UV irradiation method can be an alternative and potential technology of the traditional de-Chlorine methods. All the experimental results met the requirements of IMO resolution MEPC.159(55). This new electrochemical method and device will be very competitive for sewage treatment in the future.

Index Terms—Sewage, electrocoagulation, electrolyzing, photocatalytic reaction.
