摘要
以人工模拟的城市污水为研究对象,研究了SBR-三维电极生物膜工艺对污水中CODCr、氨氮、硝态氮和总氮的变化,以及电流强度对总氮去除的影响情况。结果表明,SBR-三维电极生物膜工艺对总氮的去除较好,可以达95%;三维电极生物膜反应器中,出水中总氮的浓度随电流的增加有明显的降低。
The aim is at to research sewage treatment of low carbon to nitrogen ratio with SBR-three dimension electrode biofilm reactors. The changes of CODCr,ammonia nitrogen,nitrate nitrogen and total nitrogen,and the influence of current intensity on total nitrogen removal were investigated. The results showed that total nitrogen removement was good and can get to 95%,and the total nitrogen concentration in the three electrode biofilm reactor decreased obviously with the increase of the current.
