铁尾矿砂水体除磷性能筛选及协同生物强化除磷效果
Screening of Water Body Phosphorus Removal Performance of Iron Tailings Sand and the Synergistic Biological Enhancement of Phosphorus Removal Effect
摘要
Abstract
[Objective]In order to solve the problem of resource utilization of a large amount of solid waste iron tailings sand in the steel industry,and to search for environmentally friendly adsorbent materials for nitrogen and phosphorus removal.[Methods]The removal performance and safety of phosphorus from water by different types of iron tailings sand in Hebei Province were investigated.To further improve the phosphorus removal efficiency,a collaborative phosphorus removal process study was conducted between iron tailings sand and the phosphorus accumulating bacterium Glutamicibacter sp.G2.[Results]The result showed that there were certain differences in the removal efficiency of phosphorus in water by different types of iron tailings sand.Taking into account the source,storage,and basic characteristics,a type of iron tailings sand H-HSY-01 with good phosphorus removal ability in water was selected.Dynamics studies had shown that the removal process of phosphorus by H-HSY-01 belongs to multi-layer chemical adsorption on non-uniform surfaces,with chemical bonding between the medium surface and the adsorbate.The combined treatment of phosphorus containing wastewater by phosphorus accumulating bacteria G2 and H-HSY-01 has a good synergistic effect.[Conclusion]Iron tailings can be used as a safe and effective adsorbent material for the ecological restoration of phosphorus polluted water bodies,while providing a new way for the resource utilization of bulk solid waste.关键词
