| Abstract: | Ammonia nitrogen removal efficiencies of five different types of substrates Minjiang sand, Tuojiang sand, Qingyijiang sand, zeolite and activated carbon by means of static adsorption experiment were compared.The Minjiang sand with the highest performance price ratio was screened to be the packing of this experiment, based on its high ammonia removal capability,low purchase costs and low transportation costs.The adsorption experimental results showed that ammonia nitrogen removal efficiencies of sand increased as contact time and dosing quantity increased. The data obtained in these experiments were in accordance with Freundlich and Langmuir isotherms. Maximum adsorption capacity of sand calculated from Langmuir Equation was 0.418 mg/g,and that was little different from measured adsorption capacity. |
