| 摘 要： | 选取广东茂名油页岩煅烧废渣作为人工湿地基质，研究了该基质的磷吸附特性。结果表明，Laagmuir方程和Fmadlich方程都能很好的拟合人工湿地基质对磷的吸附数量，其中Langrnuir等温吸附方程拟合效果更好，相关性达到0．989。通过正交试验可以得出，在低质量浓度（0-50mg／L）条件下，吸附量随着振荡时间的增加而增长，8h后增长趋势变缓；在初始质量浓度为50-100mg／L，温度为30℃条件下，振荡4h磷吸附效果最好；在高质量浓度（100—300mg/L）条件下，振荡频率越高、粒径越小、温度越高，磷吸附量也越多。

| Abstract: | Adsorption characteristics of phosphorus in substrate of a constructed wetland were studied with selected oil shale waste slag from Maoming.The results showed that: the adsorption of phosphorus in the substrates could be fitted through Langmuir,Freundlich equation well,and Langmuir equation was the optimum,relative coefficient reached 0.989.Through orthogonal test it showed that: when phosphorous concentration in solution between 0 and 50 mg/L,the phosphorus adsorption capacity increased with oscillation ti... |
