Research progress in treatment of dye wastewater by aquatic plants

The research and application status of dye wastewater treatments by the lower and large aquatic plants at home and abroad in recent years are reviewed,with focuses on the mechanics and applied technology.Analysis shows that dye wastewater treatment by aquatic plants has the advantages of low cost and high color removal rate,thus making up the inadequacy of dye wastewater treatment by the traditional biochemical process,indicating it has bright future.However,on the whole its research scope is too small,which limits its application.Selection of proper aquatic plants and improvement of color removal efficiency may become hot fields of research in the future.
