Abstract

Abstract Natural or synthetic zeolites have unique physical, chemical and structural properties that predetermine their use in many processes, including wastewater treatment. This study presents the results of our preliminary research in the field of nitrogen and phosphorus removal using adsorption and adsorptive ozonation with natural and modified zeolites. Iron-modified zeolite was the most efficient for the removal of ammonium nitrogen by adsorption. Phosphorus removal efficiency using adsorption was relatively low and natural zeolite was not suitable for the phosphorus removal at all. Ozone had no significant impact on the removal efficiency. Regeneration of loaded zeolites with ozone has also been studied. This method was partly efficient but it needs be further examined.

沸石在去除废水中大量营养物质中的应用
摘要天然或合成沸石具有独特的物理、化学和结构特性,这些特性决定了它们在许多工艺中的用途,包括废水处理。本研究介绍了我们在天然和改性沸石吸附和吸附臭氧化脱氮除磷领域的初步研究结果。铁改性沸石对氨氮的吸附去除效果最好。吸附除磷效率相对较低,天然沸石根本不适合除磷。臭氧对去除效率没有显著影响。还研究了负载沸石与臭氧的再生。这种方法在一定程度上是有效的,但还需要进一步研究。
