- Abstract:
- The biological and membrane process (pretreatment/UASB/MBR/NF/RO) was used to treat landfill leachate of a waste incineration power plant, with design capacity of 360 m3/d. The operation results showed that the process treatment effect was stable and had strong resistance to shock loading. The biological process(UASB/MBR) could effectively remove the COD, BOD5, NH3-N, TN and SS, and the membrane process (NF/RO) can further treat organic and salt to ensure the effluent reach the recycle standard. When the influent concentration of COD, BOD5, ammonia nitrogen, TN, and SS were 63 700 mg/L, 29 300 mg/L, 1 930 mg/L, 2 450 mg/L and 9 000 mg/L respectively, the relevant effluent indexes were 46.0 mg/L, 7.0 mg/L, 0.7 mg/L, 13 mg/L, 0 mg/L, respectively, the effluent quality could meet the requirements of supplementary water for open recirculating cooling water in The Reuse of Urban Recycling Water—Water Quality Standard for Industrial Uses (GB/T 19923-2005). The operation cost of the system was 34.41 yuan/m3.
