| 摘 要： | 以沸石、圆陶粒、粗砂、页岩、砾石为试验材料,研究人工湿地填料对氨氮、TP的吸附特性。结果表明,在相同进水水质和水力负荷的运行条件下,沸石对氨氮的吸附量最大,页岩的吸附量在90min时达到最大值,沸石、圆陶粒、粗砂的吸附量在120min时达到最大值,砾石的吸附量在150min时达到最大值;砾石对TP的吸附量最大,粗砂次之,沸石的最小,页岩和粗砂的吸附量在第120min时达到最大,沸石和圆陶粒的吸附量在120min后基本稳定;温度为25℃时,沸石对氨氮的吸附效果最好,砾石对TP的吸附效果最好;溶液pH值<7时,沸石对氨氮有较好的吸附效果;溶液pH值≥7时,有利于各填料对TP的吸附。

| Abstract: | Experiment was conducted on absorption properties of ammonia nitrogen and phosphorus(TP) by zeolite,ceramsite,coarse sand,shale and gravel in constructed wetland.The result showed that under the same input condition of water quality and power,zeolite had the most amount of ammonia nitrogen absorption.Shale's absorption topped by the end of 90 minutes,while zeolite,ceramsite and coarse sand's by the end of 120 minutes,and gravel at 150minutes.For TP adsorption,gravel had the maximum absorption amount,followe... |
