摘要
上海老港生活垃圾填埋场四期渗滤液处理厂升级改造工程设计规模为3200 m3/d,经脱氨预处理和膜生物反应器(MBR)生物处理后的出水采用了高清液回收率的"纳滤+纳滤浓缩液3级减量"工艺进行深度处理。实际工程运行表明:控制MBR出水COD、NH3-N、NOx--N、TN分别低于800,5,15,80 mg/L,经深度处理后出水COD、NH3-N、TN可稳定达到GB 16889-2008《生活垃圾填埋场污染控制标准》中的表2标准,系统清液得率可达97%。
The design scale of the upgrading project of the fourth-stage leachate treatment plant of Shanghai Laogang Landfill is 3200 m^3/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 NO-x-N were lower than 800,5,15 mg/L,respectively.Meanwhile,clear water recovery rate of the system could reach 97%.
