| 中文摘要: |
| 水环境污染是造成全球水资源水质性紧缺非常重要的因素。农业面源污染则是继工业源污染实施清洁生产得到有效治理之后水体污染主要的贡献者,特别是地表水中过量氮、磷的主要来源,受到越来越多的关注和重视。植物修复技术因其可以对受污染水体进行原位修复和避免二次污染等特点,逐渐被人们应用到污染水体的治理中。本文从植物修复农田退水氮、磷污染视角,综述了农田退水氮、磷在主要去除途径与影响因素方面所取得的研究进展,并针对植物修复农田退水实践中存在的问题,提出了继续强化植物组合对水污染负荷消减能力的研究,进一步扩展对植物的经济利用价值、生态景观价值和社会效益开展研究,以及深化植物修复从室内模拟到野外小区域示范、再到大区域的推广应用研究等建议,以期为进一步提升治理农田面源污染效果提供技术支撑。 |
| 英文摘要: |
| Water pollution is a main issue that contributes to the water quality-induced shortage of global water resources. After cleaner production technology successfully applied to the industrial pollution control, agricultural non-point source pollution has been the biggest contributor to water pollution, in particular, the leading source of excess nitrogen and phosphorus in surface water and gaining more attention. The phytoremediation technology has been gradually applied to improve surface water quality because of the advantages in its insitu remediation and no secondary pollution. This paper summarized the progress made on the main approaches, influencing factors and issues of removing N and P in farmland drainage water using phytoremediation. Recommendations regarding to the future research in strengthening plant combination, its economic and social efficiencies, and the implementation from small scale demonstration to large scale extension will be proposed. It would further support improving the effect of agricultural nonpoint source pollution control. |
