【Abstract】 A kind of internal tubular charged ultrafiltration membrane which is consist of sulfonated polysulfone have been developed. In this paper, the specification and properties of the ultrafiltration membrane series, and the structure of the module and the device are detailed, and it is also refered that the clean methode of the membrane surface by sponge balls is very simple for six tube module. The relation that penetrating solution flow varies with the pressures and velocities of the main current at the operation is studied. The result of the test which adopt the UF, RO and ED for treatment of the low-level radioactive waste water shows that this process will be a promising technique.更多还原
