摘要
介绍了在渗滤液排放标准提高的情况下,北方某城市垃圾填埋场渗滤液处理工程改造升级的设计方案。在分析该渗滤液水质特点和原有简单物化/一级生化工艺缺陷的基础上,提出物化/多级生化/氧化吸附/膜分离组合工艺。该工艺适于高含盐、难降解渗滤液的处理,其出水水质能够达到《生活垃圾填埋污染控制标准》(GB16889—1997)中的一级标准,部分出水经反渗透处理后可达到杂用水水质标准。
The design scheme of upgrading landfill leachate treatment project of a northern city under the condition of the stricter leachate discharge standard was introduced. Based on the analysis of the leachate characteristics and the disadvantage of original simple physicochemical/primary biochemical process, a combined physiochemical/muhistage biochemical/oxidation adsorption/membrane separation process was put forward. The process is suitable for treating the high-salinity and refractory leachate. The effluent quality can reach the first class criteria specified in the Standard for the Landfill Site for Domestic Waste （ GB 16889 - 1997 ）, and the reclaimed wastewater from reverse osmosis reactor can meet the miscellaneous wastewater quality standard.
