Abstract

The invention belongs to the technical field of ecological engineerings and relates to a purifying functional wetland plant screening pool. The purifying functional wetland plant screening pool comprises a distribution reservoir, at least two planting beds and a discharge bay, wherein the distribution reservoir and the discharge bay are connected with the planting beds respectively through pipelines. The wetland plants or plant compositions are planted in the planting bed, the sewage in the distribution reservoir is discharged into the planting bed, and various indexes of pollutants in the planting bed are determined after a period of time, such as chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP) and the like, so that the wetland plants or plant compositions with purifying functions are screened out. The wetland plants with stronger purifying functions are screened through study of purifying effects of different configuration modes of wetland plants under the field natural conditions, so that a scientific basis for water purification for polluted wetlands and restoration of degraded wetlands is provided.

Description

technical field [0001] The invention belongs to the technical field of ecological engineering and relates to a purification function type wetland plant screening pond. Background technique [0002] Wetland plants play an important role in sewage purification and other aspects. There are many kinds of wetland plants, and they have strong regional characteristics. Different wetland plants have great differences in the removal ability of pollutants. Therefore, it is of great theoretical and practical significance to screen wetland plants that are suitable for growth and have strong purification ability for wetland water purification and water environment restoration. Scholars at home and abroad have used wetland plants such as reeds, cattails and wild rice stems to construct artificial wetlands for sewage treatment. There are few reports on shrubs as plants in constructed wetlands. [0003] The earliest document on the study of my country's wetland plants is Wang Yanjie's pr...
