Study on Water Ecological Restoration Technology of River

Based on the historical review and summary of river water ecological restoration, the overall strategy and key technologies of water ecological restoration of polluted river water quality in river water for ecological restoration are analyzed. At present, physical, chemical and biological composite technologies are mainly used to carry out ecological restoration of spatial form, water quality, bottom silt, flora and fauna habitat and riparian buffer strips in river ecosystem. It is pointed out that constructed wetlands, biological floating islands and other bioremediation technologies are gradually being paid attention to, and become the main direction of the development of river water ecological remediation technology in the future. The purpose is to provide scientific reference for river ecological environment management.
