Pilot test of combined process of Ultrafiltration and Reverse Osmosis was researched in this paper, which is the advanced treatment of the MBR technology effluent of port sewage, the result suggested that this devices was feasible in technology, and the quality of effluent was stable, better than the quality standard of The Reuse of Urban Recycling Water-Water Quality for urban miscellaneous water. Shortage of fresh water resources in the port area has become restricting factors for sustainable development, and the reuse of port sewage has becoming a hot pot in research direction at present. Membrane treatment technology, as an emerging technology in high-tech field, had been widely applied in Water treatment field. In recent years, the combined of different membrane treatment technology, such as microfiltration, ultrafiltration, reverse osmosis, nanofiltration and so on, will be the development trend of reclaimed water treatment, and the effluent has been widely used for thermal power plant circulating cooling water system, boiler feedwater and urban miscellaneous water([1-3]). An Ultrafiltration-Reverse Osmosis double membrane devices has been designed in this research, for the treatment of the MBR technology effluent of port sewage, and the, efficiency of the device was discussed in this paper.
