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 C0DCr, ammonia nitrogen, nitrate nitrogen and total nitrogen, and the influence of current intensity on total nitrogen removal were in-vestigated. The results showed that total nitrogen removement was good and can get to 95% , and the total nitrogen concentration in the three elec-trode biofilm reactor decreased obviously with the increase of the current.
