摘要：

The　nitrogen　removal　effect　of　catching　bed　biofilm　reactor　based　on　traditional　biofilm　process　was　investigate.　The　result　indicates,　steady　removal　effect　with　87.81%　of　average　COD　removal　rate　was　achieved　in　various　dissolved　oxygen(DO)　concentrations.When　DO　was　between　0.7-1.1mg/L,removal　rate　for　NH4+-N　and　TN　94.7%　,53.8%,respectively.When　DO　was　controled　in1.2-2.0mg/L,　94.7%　of　average　NH4+-N　removal　rate　and　79.66%　of　average　TN　removal　rate　were　obtained.　When　DO　was　between　2.0-3.5mg/L,average　removal　rates　for　NH4+-N　and　TN　were　99.6%　and　65.1%　respectively.　The　optimal　condition　for　nitrogen　removal　effect　was　with　DO　between　1.0-2.0mg/L.　pH　was　also　a　crucial　factor　for　removal　rates　of　NH4+-N　and　TN.　The　preferable　effet　for　simultaneous　nitrification　and　denitrification　was　found　between　7.05-7.37　of　pH.　©2010　IEEE.
