摘要： PROBLEM TO BE SOLVED: To make it possible to prevent a liquid waste line from clogging by keeping the temperature to the point of adding a compound of alkali metal elements and that of an alkaline earth metal element to a liquid waste containing boron, and drying and powdering a mixture of them at the deposition temperatures of boron and both compounds or higher. SOLUTION: After a radioactive liquid waste 1 containing boric acid as a main constituent that is generated in a nuclear power plant is heated 2 at the temperature of 80 deg.C or higher, the liquid waste 1 is neutralized by adding a compound 3 of alkali metal elements such as Na and K to the liquid waste. Moreover, the boric acid as the main constituent is insolubilized by adding a compound 4 of alkaline earth metal elements such as Ca and Mg to the liquid waste 1. Then, a liquid waste containing an insoluble compound of a boric acid (a liquid waste containing an insoluble boric acid) obtained in the previous process is supplied to a dryer while keeping the temperature of the liquid waste at 80 deg. C or higher, a drying treatment 5 is carried out for the liquid waste to convert it to dried powder 6 and the volume of it is reduced. In this process, the sedimentation velocity of insoluble borate in the liquid waste can be reduced by keeping the temperature of the liquid waste at 80 deg.C or higher, which makes it possible to prevent a liquid waste line from clogging. The dried powder 6 is solidified in concurrence with a cementitions material.

摘要： PURPOSE:To shorten a neutralization time while reducing the overshoot at a pH value regardless of the kind of a soln. CONSTITUTION:The concn. of a neutralizing agent contributing to neutralization is estimated and the absorption ration of the neutralizing agent, that is, the degree of electrolytic dissociation of a weak acid is calculated from the relation between the concn. of the neutralizing agent and the concn. of a hydrogen ion and, on the basis of the calculated value, the necessary feed amt. of the neutralizing agent is estimated to operate a neutralizing agent feed pump. Since the absorptivity of the neutralizing agent is renewed at every time, a neutralizing time becomes short. Since the time constant of stirring is considered, the overshoot of a pH value caused by the charging delay of the neutralizing agent is reduced.

CONSTITUTION:First of all, a dummy waste liquid is supplied to a feed liquid tank 1, and by operating a pump 2, a valve V1 is opened, and the dummy waste liquid is supplied to an activated carbon filling vessel 3. Subsequently, COD of treating water is measured by a chemical oxygen demand meter (COD meter) installed in an outlet of the vessel 3, and at the time point when the COD reaches a prescribed value or above, the pump 2 is stopped. Next, the valve V1 is closed, a pump 7 is driven, a valve V3 is opened, and hydrogen peroxide is supplied by a prescribed quantity to the vessel 3. After this state is left as it is about 10 - 30 hours, the valve V3 is closed, a valve V2 is opened and hydrogen peroxide is exhausted to a used hydrogen peroxide receiving tank 8. After closing the valve V2 and V3, the valve V1 is opened, and by operating the pump 2, a waste liquid is supplied to the vessel 3 again, and the same operation is repeated.

摘要： PROBLEM TO BE SOLVED: To provide a processor with high removal performance of impurity, superior operation performance which can reduce operation cost and the generation amount of secondary waste. SOLUTION: A plurality of pairs of anodes 2 and cathodes 3 are placed face to face like a comb in an electrolysis tank 1 and an electrolysis coagulator/ separator 5 is constituted by connecting the anodes 2 and the cathodes 3 to a direct current source 4. A filter 6 is directly connected to the downstream of the electrolysis coagulator/separator 5. The anodes 2 and the cathodes 3 consist of electrode plates of aluminum as main material and the hole diameters of the filter 6 material are 0.45 μm. If electrolysis is applied to the washing waste liquid 7 put in the electrolysis tank 1, the suspension component in the washing waste liquid 7 is coagulated by generating aluminum ion. If hydrogen gas bubbles generated from the cathodes attach the coagulated suspension, it floats on the water surface, which is filtered with the filter 6.

摘要： PURPOSE: To obtain a good cement-solidified wastes stably by operating a solidification device continuously and automatically, saving the labor of workers and improving the efficiency of it. CONSTITUTION: A cement container 1, a sand container 2 and a water container 3 are connected to a mixer 4 through transferring pipes 1a, 2a and 3a. Transferring valves 21, 29 and 22 are respectively connected to the transferring pipes 1a, 2a and 3a. A viscometer 8 is installed in the mixer 4, and signals measured in the viscometer 8 are inputted into a fluidity controller 23, which judges whether the quality of a cement paste is good or not. If fluidity is high, judgment output signals from the fluidity controller 23 open a cement transferring valve 21. If it is low, they open a water transferring valve 22. In this way, the cement paste is adjusted to have a prescribed fluidity by supplying cement or water. The adjusted cement paste is poured into a drum 6 to solidify radioactive solid wastes 7 with the cement in it.
