中文摘要：

采用啤酒酵母菌-活性污泥协同曝气处理含铀废水，研究了其吸附过程的吸附性能及吸附动力学。实验结果表明，啤酒酵母菌-活性污泥协同对UO^2＋ 2具有良好的富集作用，在污泥质量浓度为8g／L，啤酒酵母菌加入质量浓度为10g/L（干质量），粒度为100-120目，吸附温度为25℃，曝气量为80-100L／h的条件下，对初始质量浓度为100mg／L，溶液pH值为5的铀溶液进行吸附1h，其去除率达到96.3％。啤酒酵母菌-活性污泥协同曝气处理不同初始质量浓度铀的吸附等温线符合Langmuir和Freundlich等温吸附方程，相关系数达到0.98以上；吸附动力学过程是一个动态过程，可用准二级吸附速率方程来描述，相关系数达到0.99以上。

英文摘要：

Saccharomyces cerevisiae-activated sludge was used in synergistic aeration treatment of uranium-contained wastewater. The characteristics and kinetics of this adsorption were investigated. The results indicate that saccharomyces cerevisiae （SC）-activated sludge （AS） can accumulate UO^2＋ 2 effectively from aqueous solution. The removal rate of UO^2＋ 2 can reach 96.3% after U solution with initial mass concentration 100 mg/L and pH=5 is adsorbed for 1 h under the conditions of AS mass concentration 8g/L, SC mass concentration 10g/L（dry mass）, SC granularity 100-120 mesh, adsorption temperature 25℃ and aeration capacity 80-100 L/h. The biosorption isotherms of U by SC-AS can be described by the Freundlich and the Langmurir adsorption isotherms, with the related coefficient more than 0.98. The biosorption dynamic process can be better described by a pseudo 2nd-order model, with the related coefficient more than 0.99.
