摘要/Abstract

摘要： 通过实验室土柱模拟实验，研究垃圾渗滤液污染晕中不同污染物的迁移转化规律和生物地球化学降解作用。实验结果表明：微生物在前28 d的增长速度较快，平均每天增长1.7×10⁵个；TOC在土壤中以“梭形”向前迁移，而且微生物的增长对其衰减具有明显的影响；NH⁺₄-N在土壤中以“活塞式”向前推进，其衰减和微生物的增长在短期内未见明显的关系；TOC在土壤中的迁移速度比NH⁺₄-N的迁移速度快，TOC的迁移速度约为3.0 cm/d，而NH⁺₄-N的迁移速度约为2.4 cm/d。

关键词: 渗滤液污染, 生物降解, 衰减作用, 污染晕

Abstract: A soil column was constructed to investigate transportation, transformation and the biogeochemistry process of the pollutants in the landfill leachate plume. Experimental results indicated that growth rate of microbes is high in the initial 28 days, and its average increase rate was 1.7×10⁵ per day; TOC showed shuttle-shape migration in soil. Growth rate of microbes had great impacts on the TOC attenuation; NH⁺₄N showed piston shape transportation in soil, and its attenuation had no obvious relation to microbes growth in short term. Migration rate of the TOC is higher than that of NH⁺₄-N; migration rate of TOC and NH⁺₄-N is about 3.0cm/d and 2.4 cm/d, respectively.

Key words: leachate contamination, biodegradation, attenuation process, pollution plume
