| Abstract: | The design scale of the upgrading project of the fourth-stage leachate treatment plant of Shanghai Laogang Landfill is 3200 m3/d. The effluent from negative pressure steam-stripping pretreatment and MBR biological treatment adopted the advanced treatment technology of nanofiltration & three-levels reduction of nanofiltration concentrate, with an excellent recovery rate of clear water. The actual engineering operation showed that the effluent concentrations of COD, NH3-N and TN met the standard of Table 2 in GB 16889—2008 after the advanced treatment, on the premise of the influent concentrations of COD, NH3-N and NOx--N were lower than 800, 5, 15 mg/L, respectively. Meanwhile, clear water recovery rate of the system could reach 97%. |
