垃圾渗滤液MBR-NF处理工艺的设计

垃圾渗滤液MBR-NF处理工艺的设计环境保护垃圾渗滤液MBR-NF处理工艺的设计*彭青林,曾经,禹丽娥(长沙理工大学化学与生物工程学院,湖南长沙410076)摘要:研究了湖南省耒阳市某垃圾填埋场的垃圾渗滤液的处理工艺,并进行了成本估算。该处理工艺采用膜生物反应器(MBR)为主体工艺处理垃圾渗滤液可有效的实现达标排放,包括工艺选择、主要单元说明、主要设备与构筑物以及工程的投资成本核算,通过初步核算,该垃圾渗滤液处理工艺的水处理运行成本为11132元/m3,表明该工艺不仅技术上可行,经济上也是合理的。关键词:垃圾渗滤液;膜生物反应器;纳滤DesignofMBR-NFTreatmentProcessofLandfillLeachate*PENGQing-lin,ZENGJing,YULi-e(DepartmentofChemistryandBiologicalEngineering,ChangshaUniversityofScienceandTechnology,HunanChangsha410076,China)Abstract:AlandfillleachatetreatmentprocessofalandfillsiteinLeilang,Hunanprovincewasdesigned,andthewastewatertreatmentcostwasalsoestimated.ThewastewatertreatmentprocesswasmainlycomposedofMembraneBio-reactorandNanofiltration(MBR-NF),whichmadethewastewaterdischargetoreachstandard.Theprocessselection,mainunitintroduction,majorequipmentandstructureandthecostofprojectinvestmentwerediscussed,respectively.TheestimationresultshowedthatthewastewatertreatmentcostwasRMB11132RMB/m3,whichmeantthiswastewatertreatmentwasnotonlyfeasible,butitstreatme
