铀纯化过程中会产生大量放射性废水,这些废水的处理在当下的环保要求下显得格外重要,而去除废水中有机物又是铀纯化废水处理中至关重要的一环.本文探究了电催化氧化法对铀纯化混合废水中有机物的去除效果.实验结果表明,电催化氧化法可以降低铀纯化废水 95.6%的COD值,证明了电催化氧化法对铀纯化废水中的有机物具有较高的去除能力.通过探究不同实验条件下的电催化氧化效果,进而得到去除混合废水中有机物的最佳工艺参数,即在废水pH值为 1、电流 18A(电流密度 225 A/m2)的条件下,仅需 240 min COD降低率可达 95.3%.
Study on Electrocatalytic Oxidation Decomposition of Organic Compounds in Uranium Purification Wastewater
The process of uranium purification generates a large amount of radioactive wastewater,and the treatment of these wastewater is particularly important under current environmental requirements,and the removal of organic matter in the wastewater is a crucial part of uranium purification wastewater treatment.The article explores the removal effect of organic compounds from uranium purification mixed wastewater by electrocatalytic oxidation method.The experimental results show that the electrocatalytic oxidation method can reduce the COD value of uranium purification wastewater by 95.6%,proving that the electrocatalytic oxidation method has a high removal ability for organic compounds in uranium purification wastewater.Exploring the optimal process parameters for the removal of organic compounds from mixed wastewater by electrocatalytic oxidation through controlled variable experiments.The optimal process parameters are:wastewater pH value of 1,current of 18 A(current density of 225 A/m2),and the COD decrease by 95.3 percent in just 240 minutes.
