Application of Artificial Wetlands in Water Pollution

Abstract

With the development of social economy, a large number of pollutants such as heavy metals enter water bodies. Artificial wetlands have emerged with unique advantages in removing water pollutants, like removing the phosphorus or sodium, especially suitable for developing countries. Wetland aquatic plants have a large biomass and high organic content. Using aquatic plants as raw materials for anaerobic fermentation can not only produce biogas as bioenergy, but also achieve effective disposal of aquatic plants, avoiding secondary pollution and waste of biomass resources. Based on previous research on anaerobic fermentation of aquatic plants, this article explains the two reaction mechanisms of anaerobic digestion and their applications in constructed wetlands.
