Constructed wetland is a comprehensive ecosystem. It applies the principles of species symbiosis, material recycling and regeneration, and the principle of structure and function coordination in the ecosystem. On the premise of promoting the benign cycle of pollutants in wastewater, it gives full play to the productive potential of resources, prevents environmental re pollution, and obtains the benefits of sewage treatment and recycling. Considering the nature of rural sewage, in the design, consideration should be given to the existing low-lying areas and idle ditches in the village, and efforts should be made to use unpowered or micro powered processes to achieve economic, environmental, and social benefits.
