为提高含铀废水的处理效率,改善固液分离效果,采用具有强富集性的榕树叶和具有絮凝作用的城市活性污泥,联合处理含铀废水.探讨了溶液pH值、铀溶液初始浓度、曝气量对含铀废水中铀去除效果的影响及榕树叶-活性污泥相互作用的协同效应,并讨论了榕树叶-活性污泥的等温吸附行为.研究结果表明,榕树叶-活性污泥联合处理含铀废水时产生的协同作用对铀的去除率比单独体系的几何叠加去除率约高70%;当含铀废水的初始pH值为3.5时,去除率达最大,约为100%;pH值增加,去除率明显下降;曝气量在80～100 L/h时,铀的最佳去除率达85%以上;榕树叶-活性污泥协同处理不同浓度铀的吸附等温线符合Langmuir和Freundlich等温...

To enhance the efficiency of treatment of uranium-containing wastewater, improve the liquid-solid phase separation during the process, and reduce the disposal cost, it is important to develop low-cost and easily available uranium sorbents. The capability of coalescent utilization of banyan leaves (BL) and activated sludge (AS) for removal of uranium from uranium-containing wastewater are studied. The experimental results show that the coalescent utilization of BL and AS as a uranium sorbent demonstrates a remarkable synergic effect. The uranium removal percentage is 89.6% with BL-AS combinatio...
