The application of sponge city concept in comprehensive water environment management

Currently, sponge city technology is increasingly widely and maturely applied in the treatment of black and odorous water bodies in cities, and the treatment effect after its application is also very effective. The Mingyue Lake Water Treatment Project in Nanning City has an investment of approximately 43 million US dollars. In this project, a large number of sponge city technologies are comprehensively utilized, such as constructed wetland, grass planting ditches, rainwater gardens, green roofs, and ecological permeable paving. With upstream interception and sponge city technology, Mingyue Lake Park's water body has also recovered from the black odor before treatment to the return of migratory birds and fish, and its ecosystem has been greatly improved. Nowadays, Mingyue Lake Park has become a place that integrates ecology, leisure, science and education.
