摘要
选取炉渣、炉灰、蜂窝煤渣、新型填料(WSC)、碎石、牡蛎壳为人工湿地填料,对其吸附性能进行研究。静态吸附结果表明:6种填料对磷的吸附过程都可以用Freundlich和Langmuir方程描述,WSC的吸附效果最好,其余几种填料的吸附效果依次为:炉渣>蜂窝煤渣>炉灰>牡蛎壳>碎石。理论饱和吸附值大小为:WSC>炉渣>炉灰=牡蛎壳>碎石>蜂窝煤渣。动态吸附结果表明:WSC对磷的去除率最高,达到98%以上,其次是炉渣、蜂窝煤渣、牡蛎壳、炉灰,碎石的去除率最低。
As the substrates,slag,ash,honeycomb cinder,WSC,gravel and oyster shell are studied,esp their phosphorus adsorption characteristics.The static adsorption indicates that six wetland substrates of the phosphorus adsorption processes can be described by Freundlich and Langmuir equation.WSC adsorption effect is the best among them.Other adsorption effect order is：slag honeycomb cinder ash oyster shell gravel.The order of the theoretical saturated adsorption value is：WSC slag ash = oyster shell gravel honeycomb cinder.Dynamic adsorption results show WSC with high phosphorus removal ability.The average removal efficiency is above 98%,followed by the slag,honeycomb cinder,oyster shell,ash.Gravel removal efficiency is minimum.
