摘要
稀土元素在富营养化水体中具有长期的环境效应,在水体治理中具有广阔的前景。介绍了稀土元素在治理水体富营养化中的几种应用,重点讨论了脱氮除磷稀土吸附剂的分类和各自作用特点,以及在底泥中对活性磷的稳定化和修复底泥中的作用。稀土元素作为示踪剂揭示了磷流失类型和流失途径,探讨了对水生生物的剂量-效应关系和在富营养化水体实际应用。最后总结了稀土元素应用于富营养化水体治理中存在的问题,对稀土元素在水体富营养化中的应用提出了建议。
Because of having long-term environmental effects in eutrophication of water bodies,rare earth elenients have broad prospects in water treatment.This paper introduces the application of rare earth elements in eutrophication control,and focuses on discussion about the classification and characteristics of rare earth adsorbents for phosphorus and nitrogen removal,as well as their role in stabilizing active phosphorus and repairing sediment.Rare earth elements as tracers revealed the types and ways of phosphorus loss.The dose-effect relationship of aquatic organisms and its practical application in eutrophication of water bodies was discussed.Finally,the problems in the application of rare earth elements in eutrophication control were sum-marized.Some suggestions for the application of rare earth elements in water eutrophication are proposed.
