摘要：

In　this　study,　effect　of　DO　on　simultaneous　nitrification　and　denitrification　in　catching　bed　biofilm　reactor　were　investigated,　using　three　sets　of　parallel　reactors　controlled　with　different　DO　concentration.　The　average　removal　rate　of　COD　was　reached　at　87%　over　the　range　of　03mg/L　of　DO.　Comparely,　NH4-N　removal　rate　increased　significantly　with　the　increase　of　DO　concentration.　The　optimize　DO　concentration　was　23,　the　average　removal　rate　of　NH4-N　and　TN　were　91.6%　and　64.4%　respectively.　©　2011　IEEE.
