Application of Constructed Wetlands to Treat Sewage by the Government in China

Abstract

This study examines the deployment of constructed wetlands in China, focusing on their efficacy in water purification and ecological restoration, with a case study on the city of Wuxi. Constructed wetlands, which utilize natural processes to treat wastewater, represent a sustainable alternative to conventional methods. Despite their benefits in enhancing water quality and local biodiversity, these systems pose significant challenges, notably in land use and socio-economic impacts. The research highlights the conflict between environmental initiatives and urban development, exacerbated by land scarcity and housing affordability issues. This paper proposes strategies for optimizing wetland design and suggests policy adjustments to balance ecological benefits with urban development needs, aiming for sustainable urban planning.
