Abstract: Rural wastewater treatment is a necessary measure to implement the strategy of rural revitalization. Because of simple maintenance, low operating cost and so forth, constructed wetlands (CW) have been widely used in rural wastewater treatment around the world. In recent years, many related national and local standards have been issued in China, providing references for the design and implementation of constructed wetlands. But in some specific aspects such as the pretreatment techniques, treatment goals, sizing methods and winter operations, standardized practices are yet to be achieved. This review focused on constructed wetlands in rural wastewater treatment, covering the development history, application progress, treatment process and sizing calculation, and prospected its future research direction, to provide reference and suggestions for further application and research.

Key words: constructed wetland, rural wastewater, discharge limit, treatment process, application progress
