| 摘 要： | 为降低污水中氮、磷的含量,采用吸附法去除水中的氮磷.对天然沸石进行改性、复合处理,结果表明,改性复合后沸石具备同步脱氮除磷的功能.复合沸石吸附氨氮的等温线较好地符合Freundlich等温线模型,而吸附磷的等温线较好地符合Langmuir等温线模型.叶洛维奇吸附动力学方程能更好地阐明复合沸石在脱氮除磷过程中的吸附机理.... |

| Abstract: | In order to reduce the concentration of nitrogen and phosphate remained in wastewater,adsorption processes were adopted to remove nitrogen and phosphate,in which the nature zeolite is modified and compounded as a matrix material.After the treatment,the goal of nitrogen and phosphate synchronous removal is obtained.Adsorption isotherms are depicted for nitrogen and phosphate removal. Freundlich isotherm model and Langmuir isotherm model are well matched by nitrogen and phosphate absorptions,respectively.Elov... |
