Abstract: A kind of filamentous bamboo biocarrier was applied to install contact oxidation process, and it was used to remediate translocated campus landscape water bodies,five conditions were studied on remediation feature of landscape water bodies by filamentous bamboo biocarrier.The results showed that COD,ammonia nitrogen and turbidity removal rates were 10.57%～74.34%,-83.33%～57.55% and 20.01%～100%,respectively.Bioreactor efficiencies did not fluctuate when the operation conditions were changed, and abundant biological phases could form in the system within 8 d, and short bacilus was main shape on the biocarrier.The number of the activated bacterias could decrease one order of magnitude after remediation by the filamentous bamboo biocarrier bioreactor.Hydrophilic groups, excellent biological appetency and scattered bamboo fibre are primary reasons for forming biofilm on the surface of filamentous bamboo biocarrier under lacking nutrient substrates, and macroscopical and microcosmic “netted structure”were main causes for realizing the removal of turbidity organic matters and bacterias within very short time.
