一种用于人工湿地的除磷填料及其制备方法
摘要：
一种用于人工湿地的除磷填料及其制备方法，该填料为核壳结构，内核由Ca(OH)2和三价铁盐组成，外层覆盖CaCO3；其中，Ca(OH)2、三价铁盐与CaCO3的摩尔比为1∶(0.01～0.23)∶(0.3～1.3)。该填料结构简单、强度高、不易板结、作用时间久、除磷效果好，且对水体pH值影响较小。
摘要（英）：

A dephosphorization filler for constructed wetlands and a preparation method thereof are provided, this filer is of core-shell structure, and a core comprises Ca(OH)2 and a trivalent iron salt and is covered with CaCO3, wherein a molar ratio of Ca(OH)2, the trivalent iron salt and CaCO3 is 1:(0.01-0.23):(0.3-1.3). This filler is simple in structure, high in strength, less prone to caking, long in acting time, good in dephosphorization effect and low in influence on water pH.
