摘要：

In order to increase the decontamination factor (DF) and concentration factor (CF) for the treatment of radioactive wastewater, a pellet coprecipitation microfiltration process which aimed at removing the neutron activation product Ni-63 and fission product Sr-90 was studied. In this study average DFs were (4.60 +/- 0.42) x 10(3) for nickel and 559 +/- 24 for strontium, respectively. When about 1.8 m(3) wastewater was treated, the sludge volume was significantly minimised after 24 h settling and CF reached over 1 x 10(3). DFs and CF values were improved by 1-2 orders of magnitude in this study compared with those achieved by conventional methods.
