  • 摘要: 针对垃圾填埋场渗滤液生物脱氮高耗能的问题，通过对A/O/N工艺处理垃圾渗滤液进行短程硝化反硝化调试，对溶解氧(DO)、污泥浓度(MLSS)、污泥龄(SRT)、混合液回流比、pH、碱度进行定性定量分析，研究了不同条件下垃圾渗滤液生物处理阶段COD、氨氮及总氮去除效果，探讨了影响亚硝酸盐氮积累的因素。结果表明，好氧池低溶解氧能成功启动短程硝化，垃圾渗滤液稳定实现短程硝化反硝化脱氮。运行条件为：O反应器DO浓度0.5~0.8 mg·L-1，N反应器DO浓度1.5~2.2 mg·L-1，MLSS 3 500~4 500 mg·L-1，污泥龄9~13 d，混合液回流比1 100%，N反应器pH 7.6~8.2，N反应器碱度1.1 g·L-1。短程硝化调试后，硝化阶段亚硝化率稳定在85%以上，COD、氨氮及总氮去除率分别达95%、98.6%、94.2%以上，节省30%碳源量和20%曝气量。
    Abstract: In view of the high energy consumption in biological treatment of landfill leachate, the short-cut nitrification and denitrification in the A/O/N process was debugged for treating the landfill leachate. The effects of dissolved oxygen (DO), mixed liquor suspended solids (MLSS), sludge retention time (SRT), mixture liquid reflux ratio, pH, and alkalinity on the removal efficiencies of COD, ammonia nitrogen and total nitrogen in landfill leachate by the biological treatment process under different conditions were studied, and the factors affecting the nitrite nitrogen accumulation were discussed. The results show that the short cut nitrification could be successfully start-up at low DO concentrations in the aerobic tank, the stable short cut nitrification and denitrification could be achieved from landfill leachate. The running conditions for this biological treatment process could be determined as following: DO concentration of 0.5 to 0.8 mg·L-1 in the O reactor and 1.5 to 2.2 mg·L-1 in the N reactor, MLSS concentration of 3 500 to 4 500 mg·L-1, sludge retention time 9 to 13 d, mixture liquid reflux ratio 1 100%, pH = 7.6~8.2 and alkalinity of 1.1 g·L-1 in the N reactor. After commissioning of the short cut nitrification system, nitrosation rate at nitrification stage remained above 85%, and removal efficiencies of COD, NH3-N and TN approached above 95%, 98.6% and 94.2%, respectively, 30% carbon source and 20% aeration rate were saved.
