There are several serious problems in treating shipboard wastewater due to special environmental conditions of ship, such as confined space, rolling and pitching, change of temperature and so on. It was suggested that Sequence Batch Reator (SBR) process might be suitable for overcoming above problems in terms of small size, high capacity of treating wastewater and full automation. In this study the SBR process was used for the secondary treatment of shipboard wastewater. The average removal efficiency of DOC, nitrogen, phosphorus and surfactants(MBAS) were studied and the effects of various C/N ration on the efficiency of treatment were investgated. From the experimental results it was convinced that the SBR process would be able to be used as a suitable process for removing organic matters and nitrogen in reuse system of shipboard wastewater.
