Water polluted caused by the nitrogen and phosphorus has become an important environmental problem recently, which had restricted the development of society. The elastic packing have a similar role with plant root in treatment contamination of wastewater. This study aims to indentify the nitrification and denitrification capacity of biofilm culturing in the elastic packing, which were in-situ directly applicated to urban polluted riverway. The results are as follows: (1) The biofilm nitrification capacity grew from 0.88 to 2.40, from 0.93 to 2.07, and from 0.80 to 1.93 mg·kg-1·h-1, respectively, in the water depth of 10cm, 50cm and 80cm from 0 to 10 days. Then, the values were maintained at steady levels of 1.33-1.84, 1.08 to 1.71, and 0.95 to 1.15 mg·kg-1·h-1, respectively, in the water depth of 10cm, 50cm and 80cm from 10 to 28 days. (2) Duing the 0-13 days, the biofilm denitrification capacity grew from 19.60 to 20.47, from 19.61 to 20.49, and from 19.63 to 20.63 mg·kg-1·h-1, respectively, in the water depth of 10cm, 50cm and 80cm. During the 14 to 28 day, they were fluctuate changes from 20.00 to 20.49 with a mean vlues of 20.17 mg·kg-1·h-1, from 19.99 to 20.17 with a mean value of 20.18 mg·kg-1·h-1, from 20.12 to 20.53 with a mean of 20.37 mg·kg-1·h-1, respectively, in the water depth- of 10cm, 50cm and 80cm; (3) The biofilm nitrification capacity was significantly changes as a increased of water depth, and the ranked order were as follows: 10cm>;50cm>;80cm. However, the biofilm denitrification capacity was not obvious changes as a increased of water depth during the experiment process.
