| Zusammenfassung: | To provide a reduction treatment method for an oxidizer waste solution, capable of preventing generation of acidic gas when carrying out the reduction treatment.SOLUTION: According to the reduction treatment method, an alkali pH adjuster for adjusting pH of an oxidizer waste solution is fed into the oxidizer waste solution prior to feeding a reducing agent into the oxidizer waste solution. The alkali pH adjuster neutralizes an acid formed during the reduction reaction of the oxidizer and the reducing agent to maintain the oxidizer waste solution in an alkaline condition, and thereby to prevent the generation of acidic gas.SELECTED DRAWING: Figure 2
【課題】還元処理中に酸性ガスの発生を抑制することが可能な酸化剤廃液の還元処理方法を提供する。【解決手段】還元処理方法では、酸化剤廃液に還元剤を投入する前に、該酸化剤廃液のｐＨ値を調整するためのアルカリｐＨ調整剤が酸化剤廃液に投入される。アルカリｐＨ調整剤は、酸化剤と還元剤の還元反応の際に生成される酸を中和して、酸化剤廃液の液性をアルカリ性に維持し、これにより、酸性ガスの発生を抑制する。【選択図】図２ |
