摘　　要：以凹凸棒土为主要原料,制备新型废水氨氮吸附剂。考察了吸附剂添加比例、处理时间、pH和处理温度等因素对该新型吸附剂去除废水中氨氮的影响。研究结果表明:当吸附剂添加比例为5%、处理时间为90min、pH为8.39、处理温度为常温时,所制备的新型吸附剂吸附效果最好,对废水中氨氮有良好的去除率。A new adsorbent for ammonia nitrogen waste water was prepared by palygorskite as essential material. The influences of the adsorbent content, the time, the pH value and the temperature on disposals of the adsorbent were studied by a single factor experiment design. The results showed the best ammonia nitrogen removal rate of the adsorbent was achieved when the ratio of waste water to the adsorbent was 19, the disposing time was 90min, the pH value was 8.39 and the disposing temperature was 25℃.
