摘　　要：为解决电极镀铀工艺废水的处理问题,开发了适合该工艺特殊要求的蒸发浓缩装置。该装置通过微负压蒸馏原理将废水中的水分汽化,冷凝水经检测合格后外排;蒸发器产生的残渣和固体作为放射性固体废物处理。在装置间设置了防渗基坑,用来处理设备失效或应急淋浴问题;蒸发浓缩装置采用中和罐调节废水酸碱性,并加装检测口,确保冷凝水符合标准后排放。To address the wastewater treatment issue in electrode uranium plating process,an evaporation concentration device suitable for the special requirements of this process has been developed,which can effectively reduce the discharge of radioactive process wastewater.The principle of this device is to vaporize the water in the waste liquid through micro-vacuum distillation,condense it back into liquid water,and then discharge it externally.The remaining concentrated water and solid in the evaporator are treated as radioactive solid waste.Considering the actual application scenarios,leak-proof foundation pits are set up to address equipment failure or emergency shower problems.The device uses neutralizing tanks to handle the acidity and alkalinity of the waste liquid,and is equipped with a detection port to ensure that the waste liquid after condensation meets the emission standards.
