摘要

本文研究了用远红外蒸发技术处理中放废液的工艺条件及影响因素。探讨了远红外加热器的加热距离、系统负压、废液的pH值对各种核素（

Pm、

Zr-

Nb）和1AW废液的蒸发速率和去污因数影响。并对本所0.7吨中放废液进行了实际处理，二次蒸汽冷凝液的放射性浓度为1×10

-9

Ci/l，浓缩倍数35，蒸残液已近半固体状态，需要进一步固化处理。

Abstract

The far infrared evaporation technology for treatment of lower-middle level radioactive waste liquid was investigated. The effects of the heater

Nb) and evaporaton rate were examined. About 0.7 tons of the medium liquid waste was treated; radioactive concentration of the condensate was 1×10

-9

Ci/l. The concentration factor was 35; resulted residue was in semi-solid state needing further solidification.
