摘　　要：以大洋锰结核为原料处理氨氮废水,考察了吸附时间、温度、初始NH4+浓度、液固比及pH值对吸附效果的影响,并绘制了吸附等温线。试验结果表明:在温度20℃,时间24 h,粒度-0.074 mm占82.6%,NH4+浓度375.4 mg/L,液固比100∶1,溶液pH值6的条件下,吸附NH4+的量达到20.43 mg/g。Marine manganese nodules are used as raw material treat ammonia-nitrogen wastewater. The effect factors such as adsorption time, temperature, the initial concentration of NH4 ＋ , solid to liquid ratio, and pH value are investigated and the absorption isotherm is obtained. The experiment result shows that： the absorption amount of NH4 ＋ can reach as high as 20.43 mg/g under the conditions of temperature 20℃ ,time 24 h, -0. 074 mm particle size accounting for 82.6% , concentration of NH4 ＋ 375.4 mg/L, solid to liquid ratio 100：1 and solution pH value 6.
