Abstract: According to the characteristics of contaminated surface water, a strain of Flavobacterium sp. that could remove CODcr efficiently was picked out from river substrate sludge and then immobilized. Comparing several immobilization processed, an efficient kind of carrier was found, i.e., a gel made up of 10.5% PVA, 0.5% Na·Alg, 3% activated carbon and microdose of auxin. The results showed that the immobilized Flavobacterium sp. can remove 86.27% CODcr from contaminated surface water in 78 hours, much higher than the 59.65% removal rate by free ones.
