摘　　要：将黔西南滥木厂铊矿区前期分离到的微生物菌株作为絮凝剂应用于含铊矿山废水的絮凝实验。实验结果表明,培养三天后的发酵液对矿山废水中铊的去除率最高可达到70.49%,最佳影响因子组合为:pH=8,温度为16℃,搅拌时间为4min。菌株的絮凝活性最高可达到57.32%,最佳影响因子组合为:pH=8,温度为14℃,搅拌时间为4min。铊高耐受性菌株在铊矿山废水微生物修复治理中具有较好的应用前景。The microbe strains, isolated from the Lanmuchang thallium-mineralised area in Southwest Guizhou Province, were applied with bioflocculants to remove thallium in the local Tl-rich mine water. The results showed that the thallium-removal rates were up to 70.49% and the affecting factors were pH〉temperature〉stirring time, whereas the maximum flocculation rate was up to 57.32%, and the affecting factors were pH〉 stirring time 〉temperature. The nine strains with high tolerance to thallium are thus highly recommended to apply into the treatment of the Tl-rich mine waters.
