反渗透技术处理含Pu废液的影响因素分析及应用

为了探究反渗透(reverse osmosis,RO)技术处理含Pu废液的可行性及影响因素,对含Pu废水的处理提供指导,进行了系统的反渗透实验.结果 表明:膜通量随着温度和压强的提高而提高;截留率随着压强、原水活度的提高而提高,随着温度的提高而降低,在pH为膜的等电点附近时最低;在实际废水处理中,反渗透装置始终保持稳定运行15 h,共净化处理废水8L,产水达标.可见反渗透技术对含Pu废液的处理具有良好的效果及重要的应用价值.

Analysis of factors influencing the treatment of Pu containing waste liquid by reverse osmosis technology and its application

In order to explore the feasibility and influencing factors of the treatment of Pu containing wastewater by reverse osmosis technology, and to provide guidance for the treatment of Pu containing wastewater, a systematic reverse osmosis experiment was carried out. The results show that the membrane flux increases with the increase of temperature and pressure, the retention rate increases with the increase of pressure and raw water activity, and decreases with the increase of temperature, which is the lowest near the isoelectric point of the membrane with pH value, in the actual wastewater treatment, the RO equipment worked smoothly for 15 hours , the total volume of purified wastewater is 8 L, and the produced water still reaches the standard. It can be seen that the reverse osmosis technology has good effect and important application value in the treatment of Pu containing wastewater.
