A research review and technical improvement analysis of constructed wetland systems for wastewater treatment

Abstract

Abstract: Constructed wetlands are proven efficient technologies for both wastewater treatment and reuse of water resources.Compared with conventional treatment systems, constructed wetlands were cheap,and easily operated and maintained.In recent years, these systems had been used in the purification and treatment of domestic sewage.Moreover, there was a strong potential for application in special wastewater treatment such as industrial, agricultural, wastewater with the technical improvement of the systems.The current situation of research on the systems was summarized.Purification processes by various types of wastewater treatment in wetland systems were discussed.Factors influencing treatment efficiency of the systems and their treatment performance were analyzed, and the tendency of their development and application was forecasted.
