摘要
以石灰石、沸石、粉煤灰和煤渣四种人工湿地基质为研究对象,研究了其对磷的吸附特性。结果表明:粉煤灰、沸石和石灰石对磷的吸附用Langmuir吸附等温方程描述较好;而煤渣对磷的吸附用Freundlich吸附等温方程描述较好;四种基质对磷吸附能力大小为:煤渣﹥粉煤灰﹥沸石﹥石灰石。
The characteristics of phosphorus adsorption by limestone, Zeolite, fly ash and cinder were studied. The results showed that: the Langmuir equation , could better describe the phosphorus adsorption by fly ash, zeolite and limestone; while the Fruendlich equation could better describe the phosphorus adsorption by cinder; the order of the phosphorus adsorption was as follows: cinder 〉 fly ash 〉 zeolit 〉 limestone.
