摘要
人工湿地技术通过对自然湿地的模拟,利用植物、微生物和基质的三重协同作用来达到净化污水的目的,因其净水效率高、费用低、管理方便等优点受到日益关注。本文在介绍人工湿地净水技术及其研究现状的基础上,综述了近年来国内外利用人工湿地脱氮除磷的研究进展,分析了人工湿地中氮、磷的迁移转化机理、净化效果及其影响因素,介绍了人工湿地在水产养殖外排水处理中的应用,并对今后人工湿地技术脱氮除磷的研究进行了展望,为今后人工湿地技术在水污染防治中的研究与应用提供参考依据。
By simulating natural wetlands, constructed wetlands used for clarification of sewage under interaction of vegetation, substrates and microbial assemblages were increasingly paid more attention to and it was characterized by low - cost, convenient - management and high - efficiency. In this review, the technology of constructed wetlands and its international and domestic research progress were introduced, and the recent advances in nitrogen and phosphorus removal in constructed wetlands were comprehensively summarized by analyzing their transfer and transformation processes, removal performances and influencing factors. Also, study and application of constructed wetlands in the treatment of aquacuhural wastewater were described and the future development in nitrogen and phosphorus removal was prospected in order to provide reference and verifications for further research.
