CuFC吸附-微滤工艺处理含137 Cs 废水

摘要

采用单级亚铁氰化铜（CuFC）吸附‐微滤工艺去除实验模拟废水中的137 Cs ，研究废水中137 Cs初始活度浓度（C0）、吸附时间、pH值、竞争离子以及CuFC投加量对去污因子的影响。分别用去离子水、地表水和海水配制模拟废水，当模拟废水中137 Cs的初始活度浓度分别为4.24×105、2.84×105、2.84×105 Bq／L ，吸附时间为90 min ，pH值为7，CuFC投加量为80 mg／L ，不投加竞争离子时，本工艺的去污因子分别达到2.06×104、1.62×104和9.36×101，说明CuFC吸附‐微滤工艺是一种高效的含137 Cs废水处理工艺，且具有可观的应用前景。%The craft of single grade CuFC adsorption+ microfiltration was used to treat the simulative wastewater containing 137Cs .The affects of the initial activity concentration of 137 Cs ,the adsorption time ,pH ,competing ions and the dosage of CuFC on decontamination fator(DF) were studied .The results indicate that when the adsorption time is 90 min ,pH is 7 ,the dosage of CuFC is 80 mg/L ,and add no competing ions ,DF reach 2.06 × 104 ,1.62 × 104 and 9.36 × 101 respectively for simulative wastewater made up of pure water (C0 =4.24 × 105 Bq/L) ,surface water(C0 =2.84 × 105 Bq/L ) and seawate(C0 =2.84 × 105 Bq/L ) .It indi‐cates that the craft of CuFC adsorption‐microfiltration is a high‐efficiency craft to treat wastewater containing 137Cs ,and has considerable application prospect .
