摘　　要：在分析稀土生产工艺、稀土氨氮废水产生及废水水质具体情况的基础上,详细分析黄河包头段氨氮污染状况,结果表明造成黄河包头段水质下降的原因与稀土废水中氨氮超标排放有直接关系。另外,黄河氨氮浓度在枯水期达不到功能区水质目标,说明污染主要来自工业和城镇生活的点污染源。An analysis was made to ammonia-nitrogen pollution in Baotou section of Yellow River based on the investigation of the technics of rare-earth,ammonia-nitrogen wastewater origin and wastewater quality. It was found that the deterioration of water quality in Baotou section of Yellow River was directly related to excessive emissions of ammonia nitrogen in rare earth wastewater. In addition, ammonia-nitrogen concentration didn＇t meet water quality objectives in the dry season ,which indicated that the pollution came mainly from industrial and municipal point sources pollution.
