| 摘 要： | MIEX树脂可以有效去除水源中的UV254，UV254去除率与树脂的投加量和水源水质有关，新树脂的投加量大于10ml／L时，UV254的去除率为56％-83％。树脂在连续运行103次的过程中，仍然没有明显的UV254饱和穿透现象，树脂投加量5ml／L（20600BV），UV254去除率为45％～25％；树脂投加量15ml／L（6768BV），UV254的去除率为62％～40％。该树脂单位单次的最大UV254吸附量约为0．003cm^-1（UV254）／ml（树脂）·次。 |

| Abstract: | MIEX was very efficient in removing UV254 absorbance from raw drinking water. The removal of UV254 absorbance was related to the dose of MIEX and the quality of water sources, after a fresh resin dose of more than 10 ml settled resin/L, the removal efficiency of UV254 absorbance was 56% -83%. The initial resin（ a resin dose of 5ml and 15ml settled resin/L）wasn＇t saturated after reuse 103 times, the removal efficiency of UV254 absorbance reduced from 45% to 25% after the dose of 5ml settled resin/L and reduced from 62% to 40% after the dose of 15ml settled resin/L, the max adsorption capacity of fresh resin for removing UV254 was 0.003cm^-1/ml. |
