摘要
近年来,氨氮和磷资源枯竭的问题日益突显。然而,污水中氮磷元素的超标可能导致一系列的环境问题,而将污水中的氨氮和磷元素进行有效回收可以缓解资源枯竭的压力以及水体富营养化问题。其中,以鸟粪石作为回收氨氮和磷的形式,可以将回收后的鸟粪石作为肥料进行使用,是合理且环保绿色的方法。由于反应时间短、操作过程简单、易于控制等优点,鸟粪石结晶法具有较好的应用发展前景。本文介绍了关于鸟粪石在氨氮和磷元素回收应用的研究进展,并具体分析了各种优化条件。对鸟粪石用于氮磷元素的回收利用的开展提出了展望。
In recent years,the depletion problem of ammonia nitrogen and phosphorus resources has become increasingly prominent.However,excessive nitrogen and phosphorus in sewage may lead to a series of environmental problems,and effective recovery of ammonia nitrogen and phosphorus in sewage can alleviate the pressure of resource depletion and eutrophication of water bodies.Among them,using bird guano stone as a form of recovering ammonia nitrogen and phosphorus,the recovered bird droppings can be used as fertilizer,which is a reasonable and environmentally friendly method.Due to its advantages such as short reaction time,simple operation process,and relatively easy control,the bird guano stone crystallization method has good prospects for application and development.The research progress on the application of bird guano stone in the recovery of ammonia nitrogen and phosphorus elements was introduced,and various optimization conditions were specifically analyzed.A prospect was proposed for the recycling and utilization of bird guano stone for nitrogen and phosphorus elements.
