摘要： Although a chelating agent solution having radioactive contaminants is solidified by mixing with cement and then stored, a vast storage place is required for storing an enormous amount of chelating agent solution. When such a chelating agent solution is treated with an ion-exchange resin, a large amount of ion-exchange resin is required, and a large amount of ion-exchange resin having radioactive contaminants is produced. The present invention thus provides a method of treating a chelating agent solution having radioactive contaminants, which can significantly decrease the amount of the chelating agent solution having radioactive contaminants, and which, when an ion-exchange resin is used, can significantly decrease the load on the ion-exchange resin without producing a large amount of ion-exchange resin having radioactive contaminants. In this method, a chelating agent solution having radioactive contaminants is electrolyzed by a direct current to produce various gases and eliminate the chelating property, a holding agent such as a coagulant-precipitant or a metal scavenger, which holds metal ions to form a water-insoluble substance, is then added to the chelating agent solution to form an insoluble substance which is then filtered off, and the filtrate is treated with an ion-exchange resin. The produced purified water may be collected, or a chelating agent may be added to the purified water to form a chelating agent solution used for decontaminating a radioactive contaminated substance.

摘要： The invention provides a method and apparatus for recovering a target material including using an adsorbent such as activated charcoal, the target material recovered in a continuous manner, as well as a method and an apparatus for recovering a solvent based on such a method and apparatus. The adsorbent for the target material is rotated to move the adsorbed material in direction of centrifugal force while the target material is attracted to the adsorbent. The excess target material is detached from a peripheral edge of the adsorbent by centrifugal force. The detached material is recovered by a recovery device provided in corresponding relation to the adsorbent.

摘要： The present invention relates to a method for cooling a steel plate comprising the steps of: forming a water pool with jets of cooling water being injected to impinge on one another by using one slit-nozzle and a plurality of induced laminar flow nozzles, the slit nozzle being provided in a position on an upper surface side of the steel plate, and the induced laminar flow nozzles being provided in a position on a lower surface side of the steel plate along a transfer direction and a direction perpendicular to the transfer direction; and passing the steel plate into the water pool, wherein when a top portion of the steel plate passes over the induced laminar flow nozzles located at least on the side of highest upstream, a volume of the cooling water to be injected from each of the induced laminar flow nozzles is reduced. According to the method of the present invention, when on-line cooling is performed for a hot rolled steel plate, the top portion of the steel plate can be prevented from being super cooled, and the steel plate can therefore be uniformly cooled.
