Abstract: A container filling apparatus makes it possible to discharge liquid stagnating within a filling valve. The filling valve is lowered towards a container being conveyed. Then a liquid passageway gating section is opened by pressing a bell-shaped member of the filling valve against the container, and liquid thus fills the container. The net amount of the contents to fill the container can be adjusted by vertically moving at least one of a filler liquid tank and a stopper member which limits the lower position of an intermediate spring bracket supporting a second elastic body for biasing a valve body upwardly with respect to a loading table on which the containers are supported. In addition, it is possible to open the liquid passageway gating section by lowering the filling valve with an external force. Therefore, liquid stagnating in the passageway of the filling valve can be discharged.

Abstract: A process for treating a radioactive liquid waste is disclosed, in which a radioactive liquid waste containing uranium and .beta.-decay nuclides, daughter nuclides of uranium, is treated by combination of a flocculation method using water glass as pretreatment and a subsequent ion exchange method. An approximately total amount of the uranium and a part of the .beta.-decay nuclides, daughter nuclides of uranium, in the liquid waste are captured by an amorphous silica precipitate formed by addition of the water glass and a remaining part of the .beta.-decay nuclides, daughter nuclides of uranium, is captured thereafter by the ion exchange treatment. The thus captured radioactive materials are respectively eluted from the filtered out precipitate, a radioactive solid waste, and the ion exchanger by acid treatment to be recovered as an acidic solution. Thus, the radioactive materials in the liquid waste are recovered approximately completely, thereby making the radioactivities of a final drain remarkably reduced.

Abstract: This invention relates to biological treatment of waste water using a carrier floatable on water, and more particularly to a novel process for treatment of waste water utilizing a fluidized bed which is formed by supplying waste water in a downflow operation.
