In　order　to　achieve　the　rapid　recovery　of　biological　iron　and　manganese　removal　process　in　the　low-temperature　(3~5),　three　kinds　of　recovery　methods,　including　different　filtration　methods　of　the　upper　and　lower　flow,　changing　the　the　influent　iron　concentration　and　adding　inorganic　carbon,　were　adopted　to　study　the　recovery　effect　on　the　damaged　biological　filter　column.　The　results　showed　that　three　recovery　methods　could　effectively　shorten　the　recovery　time　of　biological　filter　column　and　the　recovery　times　were　40,　54　and　35d,　Compared　with　the　conventional　recovery　mode　of　2#　filter　column,　the　recovery　times　of　1#　and　3#　filter　column　were　shortened　by　26%,　35%.　Although　the　recovery　time　was　longer　by　the　way　to　change　the　concentration　of　iron　and　manganese,　but　the　manganese　removal　performance　after　the　recovery　of　the　filter　column　was　more　stable.　From　comprehensive　consideration　of　the　recovery　effect　and　economic　rationality,　It　was　suggested　that　the　best　way　to　recover　damaged　filter　column　was　iron　and　manganese　concentration　increased　from　low　to　high　and　adding　inorganic　carbon　when　the　filtration　rate　to　2~3m/h.　©　2017,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
