摘要
在膜生物反应器中投加填料可以强化同步硝化反硝化,结果表明:在DO为1～2mg/L,C/N为20左右,pH在7～8.5之间,HRT为15h的条件下COD、NH3-N、TN的去除率能达到97.32%、100%、93.06%。阐述了填料型膜生物反应器的机理。
Simultaneous nitrification and denitrification was accelerated in MBR by adding filler. Results showed that the removal efficiency of COD, NH3-N and TN were 97.32%, 100% and 93.06% respectively at the condition of DO 1~2mg/L, C/N 20, pH 7~8.5 and HRT 15h. The mechanism of filler MBR was also described.
