- 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.
