This paper presents a summary of degrading organic compounds of nuclear laundry water by ozonation in different conditions of pH, hydrogen peroxide and ultraviolet radiation. The degradation of organic compounds was analysed by chemical oxygen demand (COD), total organic carbon (TOC) and biochemical oxygen demand (BOD). The optimal degradation conditions were at pH 7 with ozone, UV radiation and hydrogen peroxide addition. The transfer of ozone increased significantly, thus resulting in decreased treatment time compared to ozone treatment alone. The reductions of COD, TOC and BOD were 46%, 32% and 70%, respectively.
本文总结了在不同 pH 值、过氧化氢和紫外线辐射条件下臭氧对核洗衣水有机物的降解情况。通过化学需氧量（COD）、总有机碳（TOC）和生化需氧量（BOD）分析了有机物的降解情况。在 pH 值为 7 的条件下，臭氧、紫外线辐射和过氧化氢的添加达到了最佳的降解条件。臭氧的传递显著增加，因此与单独的臭氧处理相比，处理时间减少。COD、TOC 和 BOD 的去除率分别为 46%、32%和 70%。
