Abstract

Water environment pollution by human activities is one of the major factors leading to today's water crisis. Compared with traditional wastewater treatment technologies, constructed wetlands have expanded more rapidly due to various advantages that they have, such as low cost, simple maintenance, aesthetic and environmental friendly nature. Despite their rapidly increasing applications, the design of constructed wetlands needs significantly improvement towards more scientific, model-based approach, which is now an important issue of research and development. This paper investigates the mechanisms of pollutant removal in constructed wetlands that are directly affected by substrates, vegetations and water flow patterns. New, conceptual design methods are proposed, based on domestic and overseas experiences, and the impacts of several key design factors are discussed, to improve constructed wetland design.
