垃圾渗滤液MBR_NF处理工艺的设计_彭青林

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1.132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.TheestimationresultshowedthatthewastewatertreatmentcostwasRMB1.132RMB/m3,whichmeantthiswastewatertreatmentwasnotonlyfeasible,butitstreatmentcostwa
