| 摘 要： | 通过锥形瓶静态实验,研究不同参数下负锰滤料对水中锰（Mn2＋）的去除效果.实验表明：滤料粒径为2mm时,Mn2＋的去除率及实际应用效果最佳;随着负锰滤料投加量的增加,Mn2＋的去除率也随之增加;随着溶液pH值的升高,滤料对水中的Mn2＋的去除率也随之增加;若体系中有Fe2＋存在,不利于负锰滤料对Mn2＋的吸附;负锰滤料对Mn2＋吸附等温线更符合Langmuir吸附模型,属于单分子层吸附.

| Abstract: | Through the conical flask static test, different parameters to the removal efficiency of Mn2＋ with manganese oxide-coated filter are studied in the paper. The results show that when the size of filter is 2 mm, the effect is best in terms of removal efficiency and engineering application. With the increase of amount of filter, the removal efficiency of Mn2＋ also increases. The efficiency increases with the increasing of pH in solution. If the system has Fe2＋ , it will hinder the adsorption of filter to Mn2＋. Moreover, the adsorption to Mn2＋ of manganese oxide-coated filter conforms to the theory of Langmuir adsorption, and the adsorption belongs to monolayer adsorption. |
