| Summary | The radioactive materials discharged by the Fukushima Dai-ichi nuclear power station accident have flowed into and accumulated in many wastewater treatment plants (WWTPs) via sewer systems of eastern Japan. In this study, the behavior of radioactive materials in a WWTP in Fukushima was investigated to determine the mechanism by which sludge is concentrated during water and sludge treatment processes. In addition, long-term leach experiments were conducted by using radioactive incinerator ash or dewatered sludge cake including radioactive materials. |
