Through the analysis of the river water ecosystem,the necessity and feasibility of river water ecological restoration are discussed,and the method of water ecological restoration is determined ac-cording to the type of pollution source and pollution mode:the combination of"submerged plants+aquatic animals+micro-porous aeration assisted oxygenation system".Through the water ecological restoration of the heavily polluted river channel,an underwater symbiosis system based on submerged plants is constructed to restore the self-purification ability of the water body,improve the water quality in the long term,and enhance the quality of the water environment of the project.
