Based　on　our　previous　batch　experimental　research,　sand　column　experiments　of　modified　cellulose　filter　papers　loaded　with　nano　zero-valent　iron　composites　(CFP-OH-nZVI)　for　the　removal　of　hexavalent　chromium　(Cr(VI))　from　porous　media　water　were　carried　out　to　discuss　and　analyze　the　effects　of　the　initial　concentration　of　Cr(VI)　(10,　20,　and　40　mg/L),　flow　rate　(1,　3,　and　5　mL/min),　and　adsorbent　dosage　(0.76,　1.52,　and　3.04　g)　on　the　removal　of　Cr(VI).　The　Thomas　and　Yoon-Nelson　models　have　shown　good　results　in　fitting　and　analyzing　breakthrough　curves.　Through　column　dissection　experiments,　the　elemental　valence　composition　and　spatial　distribution　of　Cr　and　Fe　within　the　column　were　elucidated,　and　the　mechanism　of　Cr　(VI)　removal　was　analyzed.　In　addition,　the　two　-site　sorption　chemical　non　-equilibrium　model　in　Hydrus-1D　effectively　simulates　the　migration　behavior　of　Cr　(VI)　in　composite　porous　media　under　different　conditions.　This　study　may　provide　useful　reference　for　the　treatment　of　groundwater　contaminated　with　heavy　metals　such　as　Cr　(VI)　using　CFP-OHnZVI.
