According to the characteristics of contaminated surface water, a strain of Flavobacterium sp. which can remove CODCr efficiently was picked out from the river substrate sludge and immobilized. By comparing several immobilization processed, an efficient carrier was determined, i.e., a gel with the component of 10.5% PVA, 0.5% Na.Alg, 3% activated carbon and trace amount of auxins. The result showed that the CODCr removal efficiency of immobilized Flavobacterium sp. was 86.27%, which was much higher than that of free stains, when the treatment time was 78h.
