Advanced Treatment of Polluted Water Using Micro-Electrolysis/Biofilm-Electrode Process

  • 摘要: 为考察微电解-电极生物膜法的污水深度处理效果,以受污染河水为处理对象,以碳素纤维作为微电解和电极生物膜的电极材料,研究微电解和电极生物膜的污水处理特点及运行条件. 结果表明:微电解可有效去除污水中PN(颗粒态总氮)、PP(颗粒态总磷)、DTP(溶解性总磷)和NH3-N,去除率分别达到94%、95%、93%和98%;其中DTP的去除以与微电解产生的Fe2+的沉淀反应为主,NH3-N的去除以硝化反应为主. 微电解提高了有机物的去除率,但对DTN(溶解性总氮)的去除率较低. 电极生物膜能有效去除污水中的NO3--N,对不同进水水质的适应性较强,脱氮以自养反硝化为主,异养反硝化可有效去除剩余有机物,ρ(NO3--N)低于45.0 mg/L的污水经过电极生物膜处理后,NO3--N可被完全去除. 在HRT(水力停留时间)为8 h、电流密度为0.10 mA/cm2的条件下,微电解-电极生物膜法对各种污染物去除效果显著,工艺运行稳定,出水ρ(TN)和ρ(CODMn)平均值均低于0.5 mg/L,ρ(TP)低于0.05 mg/L,浊度小于1.0 NTU,可实现污水的深度处理.
