| Abstract: | The natural wheat husks can used as an adsorbent to remove ammonia-nitrogen from wastewater. This paper studies the influence of contact time, pH value, husks dosage, initial concentration of ammonia-nitrogen and temperature on the adsorption efficiency, and by using the adsorption isotherm equation, adsorption dynamical equation and adsorption thermodynamical equation,fits the experimental data for making clear the mechanism of husks＇ adsorbability for ammonia- nitrogen in water and providing a theoretical basis for the practical application of husks＇ denitrification. |
