摘要
对北京市某典型的垃圾填埋场、垃圾转运站、综合处理厂2016—2017年渗沥液基本化学特性、重金属、有机物等特征进行分析。在夏季化学需氧量(COD)达到60 000 mg·L^(-1)左右,生化需氧量(BOD)波动区间560～26 540 mg·L^(-1)。重金属浓度总汞0.12～2.13μg·L^(-1),总砷9.26～48.12μg·L^(-1),总铬0.11～2.32μg·L^(-1),六价铬0.04～0.98μg·L^(-1),铅13.4～106.0μg·L^(-1),镉1.56～16.70μg·L^(-1)。气相质谱联用仪(GC-MS)分析共检测出有机污染物30多种,包括酚类、胺类、杂环类、卤代物、苯环类物质。在夏季渗沥液的污染物浓度相对较高,渗沥液处理设施在夏季达到高负荷。
The basic chemical characteristics,heavy metals,organic compounds of leachate in a typical landfill,waste transfer station and comprehensive treatment plant in Beijing from2016to2017were analyzed.In summer,COD reached about60000mg·L^-1,and BOD fluctuated between560and26540mg·L^-1.Heavy metal concentrations of total mercury,total arsenic,total chromium,hexavalent chromium,lead and cadmium were respectively0.12~2.13μg·L^-1、9.26~48μg·L^-1、0.11~2.32μg·L^-1、0.04~0.98μg·L^-1、13.4~106.0μg·L^-1and1.56~16.7μg·L^-1.More than30kinds of organic pollutants including phenols,amines,heterocyclic compounds,halogenates and benzene compounds were detected by GC-MS in the leachate.In summer,the pollutant concentration of leachate was relatively high and the leachate treatment facilities reached a high load.
