苏州市某生活垃圾填埋场渗沥液处理工艺升级改造工程分析

摘要

以苏州市某生活垃圾填埋场渗沥液处理工艺升级改造为例,介绍了改造后工艺流程,并监测了1 a的进出水水质数据.实践证明,采用均质-二级生化池-MBR-纳滤/反渗透工艺可使渗沥液处理出水水质长期稳定,满足GB16889-2008污染物控制标准,且处理成本也较为合理.%Taking the promotion of leachate treatment process for one domestic waste landfill site in Suzhou as the example,the process flow after promotion was introduced.According to the survey for one year,it was shown that the combined processes of regulating,two stage biological pretreatment,membrane bioreactor,nano-filtration/reverse osmosis were able to meet the control standard of GB 16889-2008.In addition,the treatment cost is quite reasonable.
