摘要：

Leakage　of　manganese　usually　occurs　in　bio-filters　for　simultaneous　removal　of　iron　and　manganese　from　groundwater　is　conducted　in　this　paper.　The　paper　argues　that　reduction　of　MnOx　by　Fe2+　causes　the　phenomenon　of　leakage　of　manganese.　The　reaction　is　affected　mainly　by　mass　of　MnOx,　concentration　of　Fe2+　and　pH　value,　and　which　is　promoted　while　pH　value　below　5.0　and　inhibited　while　pH　value　is　over　7.5.　Released　manganese　concentrations　showed　quadratic　curve　relationship　with　mass　of　MnOx　and　also　Fe2+　concentration.
