摘要
介绍了再生水中多环芳烃(PAHs)在土壤-植物系统中的迁移转化规律,比较了不同来源PAHs在土壤中行为的差异性。提出通过制备吸附材料、采用膜技术和高级氧化等手段去除再生水中的PAHs,通过增强土壤吸附性、提高微生物活性及筛选高效吸收降解植物等阻控技术防治再生水农灌过程带来的PAHs污染,指出采取多种方法协同降解再生水-土壤-植物系统中的PAHs是未来研究的重点。
In this paper,the migration and transformation of polycyclic aromatic hydrocarbons(PAHs)in reclaimed water in the soil-plant system were introduced,and the behavioral differences of PAHs in the soil from different sources were compared.It proposed to remove PAHs from reclaimed water by means of adsorption materials,membrane technology and advanced oxidation,and by enhancing soil adsorption,improving microbial activity,screening plants that could absorb and degrade PAHs efficiently.It pointed out that multiple methods collaboration in degrading PAHs in reclaimed water-soil-plant system was the focus of future research.
