Advanced Treatment of Landfill Leachate by Combined Process of Partial Nitrification and Anaerobic Ammonium Oxidation

  • 摘要: 为解决垃圾渗滤液中高浓度污染物对微生物的毒性抑制、生物处理出水有机物或氮不达标及投加碳源成本高的问题,采用UASB(上流式厌氧污泥床)-A/O(缺氧/好氧)反应器-ANAMMOXR(厌氧氨氧化反应器)工艺,通过短程硝化-ANAMMOX(厌氧氨氧化)深度处理实际垃圾渗滤液与生活污水混和液(体积比为1∶10),其ρ(CODCr)、ρ(NH4+-N)和ρ(TN)分别为(750±30)(290±10)和(300±10)mg/L,试验共进行90 d. 结果表明:CODCr、NH4+-N和TN的去除率分别为88%±1%、95%±1%和91%±1%,最终出水质量浓度分别为(67±5)(15±2)和(35±5)mg/L,满足GB 16889—2008《生活垃圾填埋场污染控制标准》的排放要求. A/O反应器中的ρ(FA)(FA为游离氨)在0.21~1.38 mg/L之间,可抑制NOB(硝酸细菌),使AOB(氨氧化细菌)成为优势菌种,从而实现并维持NO2--N积累率(70%~96%)较高的短程硝化,继而在ANAMMOXR中通过ANAMMOX去除残余NH4+-N和NO2--N,实现系统对氮的深度去除.
