摘　　要：以玉米秸秆为原料,采用微波加热-氯化锌活化法进行改性,通过静态试验研究了玉米秸秆投加量、pH、温度等因素对养猪废水中氨氮去除率的影响。结果表明,吸附剂对模拟废水中氨氮的最高去除率可达85%以上;当pH在8.0～10.0间、温度为20～30℃、吸附剂投加量为8 g/L,吸附时间为60 min时达最佳去除效果。Adsorption of NH3-N from swine wastewater onto modified corn stalk impregnated with zinc chloride by microwave heating was investigated.The adsorption was studied by considering the effects of various parameters on the removal rate of NH3-N,such as pH,the dosage of absorbent and temperature.The results showed that the modified absorbent used in this study was efficient,with a removal ratio of NH3-N up to 85 % or more.Optimum results of NH3-N removal were obtained with a pH of 8.0～10.0,at 20～30 ℃ and with an adsorbent dosage of 8 g？L-1 and an adsorption time of 60 min.
