Nitrogen Removal Performance and Characteristics of Granular Sludge in ANAMMOX Reactor Fed with Mature Landfill Leachate

  • 摘要: 为研究ANAMMOX(厌氧氨氧化)工艺处理晚期垃圾渗滤液过程中氮转化途径的变化及颗粒污泥特性,采用2套ANAMMOX-UASB生物膜反应器(1#系统和2#系统)分别处理晚期垃圾渗滤液和无机配水,考察两种水质条件下ANAMMOX系统的脱氮性能,并对稳定运行时期两个系统颗粒污泥中ANAMMOX菌活性、硝化活性、反硝化活性及其污泥理化特性进行对比. 结果表明:1#系统经过连续培养逐渐适应了晚期垃圾渗滤液,实现了ANAMMOX耦合异养反硝化高效脱氮;稳定期1#系统和2#系统中TN的平均去除率分别为86.66%和76.77%. 1#系统和2#系统的颗粒污泥均具有ANAMMOX活性、硝化活性和反硝化活性,1#系统中颗粒污泥ANAMMOX活性和硝化活性较2#系统略有降低,而反硝化活性则大有提高;两个系统中ANAMMOX过程对TN去除速率分别为0.286和0.301 g/(g·d). 1#系统中颗粒污泥呈红褐色,2#系统中颗粒污泥呈砖红色,两个系统中粒径>1.5~2.5 mm的颗粒污泥所占比例分别为66.10%和50.67%,基本处于传质作用最佳的区间.
