Research on the Selection and Application of Aquatic Plants in Constructed Wetlands -- Taking Qinyuan Artificial Lake of Guangxi Polytechnic of Construction as an Example

Abstract The direct absorption of aquatic plants in artificial lake, adsorption of pollutants, indirect improvement of artificial lake environment and promote microbial water purification and other environmental protection effects are increasingly obvious. Taking Qinyuan artificial lake of Guangxi Polytechnic of Construction as an example, this paper selects aquatic plants suitable for local environment with strong decontamination ability, good landscape effect and high economic value in the constructed artificial lake wetland system, which plays an important role in purifying sewage in the campus and the overall environment and achieves the expected purpose. Through this case study, the role of aquatic plants in artificial lake in sewage purification and wetland landscape construction was studied, so as to provide theoretical basis for the application of aquatic plants in artificial wetland in water purification.
