摘　　要：针对东莞运河氮、磷浓度较低的污染特点,以人造沸石、活性炭、高岭土为吸附剂进行吸附实验研究,确定不同吸附剂的最佳反应时间和最佳投入量。结果表明,活性炭对水中TN的去除效果最佳,去除率达61.9%;高岭土具有优异的除磷效果,去除率达79.21%;人造沸石对TN的去除效果一般,而对TP完全没有去除效果,反而会提高TP的浓度。As the pollution characteristics of N,P concentration is low,the paper does the experiment to determine the optimal reaction time and optimal input amount by three adsorption materials： artificial zeolite,activated carbon and kaolin.The results show that,activated carbon has the best removal rate for TN,removal rate reaches 61.9%;kaolin has excellent removal,efficiency,removal rate reaches 79.21%;artificial zeolite has the more removal rate for TN,and has no removal efficiency for TP,instead it will improving the concentration of TP.
