多级膜组合工艺处理不同时期城市生活垃圾渗滤液工程实例

摘要

This paper conducted the investigation on the treatment system of leachate from municipal solid waste landfill in some cities of Guangxi,and the results indicated that the process of “biochemical treatment and multistage membrane combination”could finely adapt to the changes of water quality of the waste leachate in different periods,and the effluent met the requirements of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 1 6889-2008).The process has the advantages of high efficien-cy,low running cost,small occupation of land,and is of high value of promotion and application in the treat-ment of leachate from municipal solid waste landfill in medium and small sized towns in the future.%通过对广西若干城市垃圾填埋场渗滤液处理系统的调查，采用“生化处理+多级膜组合”工艺能很好适应不同时期垃圾渗滤液的水质波动变化，出水可稳定达到 GB16889-2008《生活垃圾填埋场污染控制标准》的要求。该工艺处理效率高、运行成本低、占地小，对于未来在中小城镇垃圾渗滤液处理领域具有很好的推广应用价值。
