摘要
应用广泛的水平潜流人工湿地系统对有机物和悬浮物有较高的去除率,但是对营养盐的去除率是较低的,因此各种类型的湿地被组合起来以提高去除效果。文章总结了近年来国内外水平潜流湿地及组合人工湿地系统的研究现状和问题,探讨了污水在人工湿地系统中的净化机理及影响因素,并预测其研究与应用发展的趋势,为人工湿地污水净化技术的应用研究提供了有益的参考。
As widly used horizontal sub-surface flow constructed wetland system has a higher removal efficiency for organic matters and suspended matters, but the removal efficiency for nutrient salt was lower, several types of wetland systems were combined to improve the removal efficiency. The research status and problems of horizontal sub-surface flow and hybrid constructed wetland systems in China and abroad were summarized, the mechnisms and the influencing factors of constructed wetland system for wastewater purification were discussed, meanwhile, the tendency of their development and application was forecasted, which provide a beneficial reference for the application research of the constructed wetland technology in wastewater purification.
