| Abstract: | Natural zeolite which is native to Henan province and Single factor experiment are used in this experiment.grain size,rotate speed,dosage which are the factors in nitrogen and phosphorus removal process are considered.At the same time,The kinetics of NH+4 adsorption by this zeolite was investigated and the isothermal adsorp-tion experiments were carried out.The results show that the best adsorption effect is that grain size is less than 0.25 mm and the rotate speed is 100 r/min and the dosage is 42 g/L.The process of ammonium adsorption by the natural zeolite is in accordance with Langmuir adsorption isotherm.The maximum of NH+4 adsorption by the zeolite is 8.116 9 mg/g. |
