N2 - The changes of concentrations of pH, DO, COD Cr, NH 4 +-N and NO 3 --N in Biofilm Grid-Integrated Vertical-flow Constructed Wetlands(BFG-IVCWs)by treating the urban malodorous river were measured. After 45 days, DO had its own distribution and changing regulation, the removal rate of COD Cr reach to 45%, at meantime, the removal rate of NO 3 --N are over 50%. The diversity of microbial community and its succession were analyzed by PCR-DGGE fingerprint. The result shows: the removal rate of CODCr and NH 4 +-N along the river flow gradually rises, and the removal rate of NO 3 --N rises at last. The removal of pollutants mainly happened in the down-flow system of the BFG-IVCWs. The differences of characters of biofilm and environmental condition of different positions made the microbial community structure diversity variable. Three kinds of biofilms (W3, W5 and W7) were analyzed with Shannon-Wiener and Cs indices and the value in position W3 was the highest.
