摘要:分析了某生活垃圾填埋场渗滤液中16种优先控制多环芳烃(PAHs)的浓度水平和季节分布特征,考察了基于膜生物反应器联合纳滤(MBR/NF)的渗滤液处理工艺对PAHs的去除效果,同时探讨了该填埋场对周围水体环境的影响。结果表明,PAHs在填埋场渗滤液中的总质量浓度为13.0~45.8μg/L;MBR/NF处理工艺对渗滤液中目标PAHs的去除率可达到95.4%。填埋场周围地表水中检出6种优先控制PAHs,总质量浓度为78.6~93.2 ng/L,略高于背景值;地下水中检出7种优先控制PAHs,总质量浓度为59.5~80.5 ng/L,明显高于背景值。因此,所调查垃圾填埋场的PAHs对周围地表水环境的影响较小,但对地下水有一定的影响。
In this study,the concentration level and seasonal variation of 16 priority polycyclic aromatic hydrocarbons(PAHs)in the leachate from a municipal solid waste landfill were analyzed.The PAHs removal efficiency of the employed leachate treatment process of membrane bioreactor combined with nanofiltration(MBR/NF),and the influence of the landfill on the surrounding water environment were investigated.Results showed that the concentration of total PAHs in landfill leachate were in the range of 13.0-45.8μg/L.The removal efficiency of target PAHs reached 95.4%by the adopted MBR/NF treatment process.Six of the priority PAHs were detected in the surface water around the landfill site and the total concentration was in the range of 78.6-93.2 ng/L,which was slightly higher than those found in the background values.Seven of the priority PAHs were detected in the groundwater and the total concentration was in the range of 59.5-80.5 ng/L,which was obviously higher than those found in the background,indicating that PAHs of the investigated landfill sites had little influence on the surrounding water environment,but a certain influence on groundwater.
