- 摘要:
- 介绍了武汉陈家冲生活垃圾卫生填埋场采用BBR——基于芽孢杆菌（Bacillus）为优势菌群的生物处理系统+Fenton氧化+BAF组合工艺处理垃圾渗滤液原液的工程实例。实际运行数据表明，该工艺对垃圾渗滤液中的有机物、NH4+-N及TN具有良好且稳定的去除效果。当BBR系统进水COD≤14 000 mg/L、NH4+-N≤2 500 mg/L、TN≤3 000 mg/L时，BBR系统出水COD≤1 300 mg/L、NH4+-N≤28 mg/L、TN≤275 mg/L；深度处理段出水COD≤96 mg/L、NH4+-N≤7.6 mg/L、TN<40 mg/L，出水各项指标均达到了《生活垃圾填埋场污染控制标准》（GB 16889—2008）。组合工艺处理成本为103.20 元/t，具有良好的经济效益和环境效益。
- Abstract:
- A combined process of BBR (a biological treatment system based on Bacillus as the dominant bacteria), Fenton oxidation, and BAF is used to treat landfill leachate produced from Chenjiachong domestic waste sanitary landfill in Wuhan. The actual data showed that the process had satisfactory and stable removal performance on organic matter, NH4+-N and TN in landfill leachate. When the influent concentrations of COD, NH4+-N and TN were within 14 000 mg/L, 2 500 mg/L and 3 000 mg/L, respectively, the effluent concentrations of the biological treatment section were within 1 300 mg/L, 28 mg/L and 275 mg/L, respectively, and the effluent concentrations of the advanced processing section were within 96 mg/L, 7.6 mg/L and 40 mg/L, respectively. All the effluent indexes met the requirements of the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008), and the operation cost of the combined process is 103.20 yuan/t, which has good economic and environmental benefits.
