Research Progress of Ammonia-Nitrogen Adsorption by Use of Non-food Biomass
As a kind of cheap, easily accessible and environmentally-freindly absorbent, non-food biomass is very effective in treating the ammonia-nitrogen in wastewater. This paper briefly introduced the processing method of ammonia nitrogen in wastewater treatment, focusing on the current situation of treating ammonia-ni-trogen by non-food biomass. Then, different kinds of non-food biomass were modified in various ways for am-monia-nitrogen adsorption, and the mechanism of adsorption was expounded accordingly. Based on the existing research findings,the key points and prospects of its future were presented.
