本発明は、原子力発電設備で発生する廃液の処理法に係

関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for treating waste liquid generated in nuclear power generation equipment, and particularly to an ion exchange type concentration treatment apparatus suitable for concentration treatment.
従来は、原子力発電設備で発生する廃液中のナトリウム

た。Conventionally, sodium sulfate (Na2SOa) was precipitated when concentrated due to sodium ions (Nap) and sulfate ions (SO42-) in the waste liquid generated at nuclear power generation facilities, so a heater to prevent precipitation was installed in the line that transfers the concentrated waste liquid. The temperature was controlled to prevent precipitation.

ある。Conventional concentration processing methods require a precipitation prevention heater, which makes temperature control complicated, and often results in failures in the control relationships that make it impossible to perform concentration processing. Furthermore, due to the precipitation of NazSOa and chlorine ions (CQ-) contained in the waste liquid, many corrosion problems occur in the concentrator or the transfer piping for the concentrated waste liquid, so high-grade materials with good corrosion resistance are used. The reality is that there are.
本発明の目的は、これら析出および腐食の要因となる不
純物イオン（Ｎ ａ ＋、 Ｓ ０ａ２−、 ＣＱ−等
）を除去して濃縮処理することにある。An object of the present invention is to perform concentration treatment by removing impurity ions (Na +, S 0a2-, CQ-, etc.) that cause these precipitations and corrosion.
上記目的は、濃縮処理する前段設備として、イオン交換
能力を有する樹脂もったイオン交換装置を設けることに
より、達成される。The above object is achieved by providing an ion exchange device with a resin having ion exchange ability as a pre-concentration facility.

が発生しにくくなる。By removing S 04''-, CQ-, etc.), sodium sulfate (NazSO4) does not precipitate even if the waste liquid is concentrated, and CQ-, which causes corrosion, is removed, making corrosion less likely to occur.
以下、本発明の一実施例を図により説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

イオンが極力少い状態で廃液を濃縮処理する。A concentration bag R4 for concentrating waste liquid through the ion exchange device 3 of the present invention by a waste liquid transfer pump 2 for transferring waste liquid from a waste liquid receiving tank 1 for receiving waste liquid generated in nuclear power generation equipment. will be transferred to. Concentrator 4
The steam generated is condensed in the condenser 6, and the concentrated waste liquid is transferred to the concentrated waste liquid receiving tank 5. The present invention deals with the treatment of Na + and S 042- contained in the waste liquid in the waste liquid receiving tank 1.
, CI), -, etc. are removed by the ion exchange resin in the ion exchange bag W3, and the waste liquid is concentrated in a state where the impurity ions that cause precipitation or corrosion are as few as possible.

むため、コスト低減にもつながる。According to the present invention, since the precipitation prevention heater can be omitted, there is no need for temperature control, and troubles related to electricity and control can be reduced. In addition, since impurity ions (CI2-, etc.) that cause corrosion are removed, problems caused by corrosion can be reduced, and there is no need to use conventional high-grade corrosion-resistant materials for the concentrator and the piping around it. This also leads to cost reduction.
