Abstract

The technology core of biological removal of iron and manganese by contact oxidation is iron and manganese oxidizing bacteria. This article made a study on down flow and up flow filtration, the results show that down flow filtration of the homogenous filter medium is more adapted to the reproduction of biotic formation. Homogeneous filter increase the depth of effective biological filter and the biomass that develop the bio-chemical capability of the biological filter. Homogeneous filter increase removal capability of Fe/Mn and alleviate the formation of sludge cake, which can get a quite backwash. Down flow homogeneous biological filter can solve some engineering problems of heterogeneous up flow filtration. The down flow homogeneous biological filter is more adapted to the removal of Fe/Mn in groundwater.
