摘  要:
[目的]探讨6种人工湿地填料对水体中氨氮、总磷污染物的处理效果。[方法]通过静态摇床试验,研究沸石、火山石、蛭石、柱状活性炭、生物陶粒、无烟煤填料吸附氨氮和总磷的能力,建立各填料等温吸附模型。[结果]沸石对氨氮的吸附效果最好,蛭石、火山石次之,而柱状活性炭、生物陶粒、无烟煤对氨氮的吸附效果较差;柱状活性炭、火山石对总磷的吸附效果较好,其他填料对总磷的吸附效果较差;6种填料的等温吸附过程的拟合结果符合Freundlich吸附模型。[结论]从吸附氨氮、总磷性能的角度考虑,沸石、火山石是人工湿地填料较好的选择。

摘  要:
[Objective] The aim was to discuss the processing effect of six artificial wetland substrates on ammonia nitrogen,total phosphorus in water.[Method] The adsorption of ammonia nitrogen and phosphorus of six constructed wetland substrates,including zeolite,volcanic rock,vermiculite,columnar activated carbon,bio-ceramic and anthracite,were studied by static shaking experiments and isothermal adsorption model was established.[Result] According to experiment results,for ammonia nitrogen adsorption,zeolite performed the best,followed by vermiculite and volcanic rock; for phosphorus adsorption,columnar activated carbon and volcanic rock were both in the top position. The adsorption isotherm of the results was in accordance with the Freundlich isotherm adsorption model. [Conclusion] Considering the adsorption of ammonia nitrogen and total phosphorus,zeolite,volcanic rock are better choice for artificial wetland substrates.
