| Abstract: |
| In this paper, the ammonia-nitrogen wastewater was treated by Marine Manganese Nodules, The effect factors such as adsorption time, temperature, the initial concentration of NH4 , solid to liquid ratio ,and pH value were investigated,and the absorption isotherm was obtained. The experiment result shows that: the absorption amount of NH4 was up to 20.43mg/g under the conditions of temperature 20℃,time 24hours,-200mesh particle size accounting for 82.6%, concentration of NH4 375.4 mg/L, solid to liquid ratio 100:1, and solution PH 6. |
