Application of Constructed Wetland to Rural Domestic Wastewater Treatment in China

Abstract:

Constructed wetland is a new wastewater treatment technology. It not only is more effective in wastewater treatment, but also has good eco-landscapes value. According to the characteristics of domestic wastewater discharge in rural, constructed wetlands is a key technology to solving this problem in China. Application of constructed wetland to Chinese rural domestic wastewater treatment was reviewed in this paper. On this basis, the issues in the application of constructed wetland encountered, and future trends are discussed. On the one hand, constructed wetlands were prone to clogging and low nitrogen removal efficiency. On the other hand, some existing constructed wetlands were abandoned due to poor maintenance and management. Therefore, in order to play better the role of wastewater treatment, anti-blocking ability and denitrification efficiency of constructed wetlands should be improved. Meanwhile, the maintenance and management of constructed wetlands should be strengthened. Application of constructed wetlands in the rural area provides a strong guarantee for sustainable development of rural economy.
