Installation for reducing organic carbon in boric acid solution

摘要

The device for the reduction of organic carbon in the acid solution, wherein the reduction is carried out by multistage cleaning mechanism is a boric acid solution first irradiated by UV radiation in the UV lamp (3), thereby the decomposition of organic substances in the presence of an oxidizing agent, hydrogen peroxide H sub.2.nOsub.2.n.nebo potassium peroxodisulfate K.sub.2.nSsub.2.nOsub.8.n .. The addition of the oxidizing agent ensures pump (5). Then, in this apparatus the solution passed through a bed of activated carbon (6) on which it is removed by the hydrogen peroxide or other peroxy used as radical initiator. Further purification of boric acid solution takes place after the flow through the vent tank Mixed-bed plants (9) with a mixture of strongly acidic cation and strongly basic anion exchanger, thus providing a sufficient purity of the boric acid solution. This solution can be applied to nuclear power plant without negative effects through deposition of organic substances on the surfaces of the system, because it does not impair the heat transfer processes and thus no cooling of the entire process, whereby the flow device provided pumps (2, 8).
