With　the　sample　made　up　of　distilled　water,　the　effect　of　soluble　reactive　phosphorus　removal　by　Fe-Mn　bimetal　oxide　(FMO)　was　investigated　in　laboratory　scale　in　this　article.　Furthermore,　the　surface　chemistry　of　FMO　was　studied,　and　its　phosphorus　removal　mechanism　was　analyzed　as　well.　The　results　showed　that　under　the　experimental　condition,　FMO　had　good　effect　of　soluble　reactive　phosphorus　removal　at　each　dosage.　Especially　when　the　dosage　was　10　milligrame　per　liter　(mg/L),　the　rate　of　the　soluble　reactive　phosphorus　removal　of　the　filtration　water　was　quite　high,　up　to　nearly　100%.　Mainly　made　up　of　delta　manganese　dioxide(δ-MnO2)　and　ferric　hydroxide　[Fe(OH)　3],　FMO　as　a　kind　of　compound　combining　the　advantages　of　δ-MnO2　and　ferric　coagulant　well,　was　characterized　by　small　particle　size　,　large　BET(Brunauer,　Emmett,　Teller)　surface　area[146.221　square　per　gram(m2/g)]　and　abundant　macroporous.　Therefore,　FMO　had　good　effect　on　soluble　reactive　phosphorus　removal.　©2009　IEEE.
