摘　　要：沸石作为一种新型生物载体用于水处理领域,具有很好的缓冲氨氮进水冲击负荷的能力,能有效地去除水中各种形态的氮,可以深度处理二级出水,使其达到回用的标准。介绍了沸石脱除氨氮的原理和再生机制,综述了国内外应用天然沸石、改性沸石以及生化结合沸石在氨氮废水处理方面的研究现状,并展望了沸石尤其是生化结合沸石在氨氮废水处理上的应用前景。Bio-zeolite technology is capable of buffering shock loads well. It can be used in advanced wastwater treatment in combination with other process to remove various kinds of nitrogen in the wastewater effectively and can be recycled. The principle of ammonia-nitrogen removal by zeolite and its regeneration mechanism are briefly introduced. The applications of natural zeolite, modified zeolite and bio-zeolite in removal of ammonia from wastewater both in China and abroad are summarized. The potential value of zeolite in treatment of ammonia-nitrogen wastwater is prospected.
