摘　　要：通过滤柱小试研究了黑化砂对水中铊的处理能力,并探讨了去除机理。结果表明,石英砂新砂对铊的去除能力较弱,黑化砂通过物理、化学和生物共同作用,能将0.5μg/L铊降至标准限值(0.1μg/L)以下。黑化物质主要由氧锰化合物构成,滤料使用年限越长,对铊的去除效果越佳。The treatment capacity of the blacken quartz sand on thallium in water was investigated through the bench-scale experiment of filter column,and the mechanism of its removal was discussed.New guartz had a weak removal effect of thallium.The blacken sand could reduce 0.5μg/L thallium to below the standard limit(0.1μg/L)through physical,chemical and biological interaction.O-Mn compounds was the main composition of blackening substance,and the longer the service life of the filter material was,the better the removal effect of thallium could achieve.
