Description
本発明は、放射性物質を含有する被処理水（放射能汚染水）を接触させる、該被処理水中の放射性物質を吸着除去して放射能濃度を低減させる難溶性フェロシアン化合物を含有する第一の放射性物質吸着層（１）と、前記放射性物質吸着層（１）からの放射能濃度が低減された被処理水を接触させる、放射性物質を吸着除去する難溶性フェロシアン化合物の含有率が前記放射性物質吸着層（１）よりも高い第二の放射性物質吸着層（２）と、を有することを特徴とする放射能汚染水の処理装置を提案する。 The present invention comprises a first solution containing a sparingly soluble ferrocyan compound that reduces the radioactivity concentration by adsorbing and removing the radioactive material in the water to be treated, which is brought into contact with the water to be treated (radioactive contaminated water) containing the radioactive material. The content rate of the hardly soluble ferrocyan compound for adsorbing and removing the radioactive material, wherein the radioactive material adsorbing layer (1) is contacted with the water to be treated with reduced radioactive concentration from the radioactive material adsorbing layer (1) is A treatment apparatus for radioactive contaminated water, characterized by comprising a second radioactive substance adsorption layer (2) higher than the radioactive substance adsorption layer (1) .
本発明はまた、放射性物質を含有する被処理水（放射能汚染水）を、充填容積に対する難溶性フェロシアン化合物の含有質量の比率が０．４ｇ／Ｌ以上、且つ１１ｇ／Ｌ以下の放射性物質吸着層（１）に通水し、その後、充填容積に対する難溶性フェロシアン化合物の含有質量の比率が１１ｇ／Ｌよりも高く、且つ５５０ｇ／Ｌ以下の放射性物質吸着層（２）に通水することを特徴とする放射能汚染水の処理方法を提案する。 The present invention also provides a radioactive substance having a ratio of the mass of the sparingly soluble ferrocyan compound to the filling volume of 0.4 g / L or more and 11 g / L or less of water to be treated (radioactive contaminated water) containing the radioactive substance. Water is passed through the adsorbing layer (1), and then the water is passed through the radioactive material adsorbing layer (2) having a ratio of the mass content of the poorly soluble ferrocyan compound to the filling volume higher than 11 g / L and 550 g / L or less. We propose a treatment method for radioactively contaminated water.
さらに本発明は、放射能汚染水の除洗方法および処理装置において、放射性物質吸着層１又は放射性物質吸着層２又はこれら両方の層が、水溶性フェロシアン化合物を吸着剤する作用を有する水溶性フェロシアン化合物吸着剤を含有するか、或いは、放射性物質吸着層１及び放射性物質吸着層２とは異なる層として、水溶性フェロシアン化合物吸着剤を含有するＣＮ吸着層３を備えた放射能汚染水の除洗方法および処理装置を提案する。 Furthermore, the present invention provides a method and apparatus for removing radioactively contaminated water, wherein the radioactive substance adsorbing layer 1 or the radioactive substance adsorbing layer 2 or both of them have a water-soluble ferrocyan compound-adsorbing action. Radioactive contaminated water containing a ferrous compound adsorbent or a CN adsorbing layer 3 containing a water-soluble ferrocyanide adsorbent as a layer different from the radioactive substance adsorbing layer 1 and the radioactive substance adsorbing layer 2 A cleaning method and a processing apparatus are proposed.
また、難溶性フェロシアン化合物を放射能汚染水に加えると、水溶性フェロシアン化合物が処理水中に一部溶解する場合がある。フェロシアン化合物自体には毒性は無いものの、環境基準や排水基準で規定されている全シアン量が増えることになるため、好ましいことではない。そこで、放射能汚染水の除洗方法および処理装置において、放射性物質吸着層１又は放射性物質吸着層２又はこれら両方の層が、水溶性フェロシアン化合物を吸着剤する作用を有する水溶性フェロシアン化合物吸着剤を含有するか、或いは、放射性物質吸着層１及び放射性物質吸着層２とは異なる層として、水溶性フェロシアン化合物吸着剤を含有するＣＮ吸着層３を備えることにより、フェロシアン化合物が処理水中に溶解するのを抑制することができ、処理水の全シアン量を抑制することができる。 Moreover, when a poorly soluble ferrocyan compound is added to radioactively contaminated water, the water-soluble ferrocyan compound may partially dissolve in the treated water. Although the ferrocyan compound itself is not toxic, it is not preferable because the total cyan amount specified by the environmental standards and wastewater standards increases. Therefore, in the method and apparatus for removing radioactively contaminated water, the water-soluble ferrocyan compound in which the radioactive substance adsorbing layer 1 or the radioactive substance adsorbing layer 2 or both have an action of adsorbing the water-soluble ferrocyan compound. A ferrocyan compound is treated by providing a CN adsorbing layer 3 containing a water-soluble ferrocyan compound adsorbent as a layer different from the radioactive material adsorbing layer 1 and the radioactive material adsorbing layer 2 containing the adsorbing agent. Dissolution in water can be suppressed, and the total cyan content of treated water can be suppressed.
