Treatment of Low-Level Wastewater of Pu Using Coagulationand Microfiltration Technological Process

The coagulation and microfiltration combined technological process (CMF) was used to treat the low-level radioactive ²³⁹Pu wastewater. This paper referred to the effect of correlation parameters on cleaning efficiency, such as the content of Fe²⁺and pH of the effluent. The results of test show that the removal efficiency is higher than 99.9% when the content of the Fe²⁺ is 3560 mg/L and pH of the effluent is between 6.5 and 9.0. The proof test of the ²³⁹Pu wastewater containing ²³⁸U and ²⁴¹Am was done and the integrated experimental technological process is established. The results show that the α removed efficiency of 1 stage is 99.87%.
