Siphon pipes are laid at the rear end of the physical filter belt 2 and the front end of a sand wall 14 formed by sea sand. The siphon tube is used for discharging water accumulated in a dead water area in the river channel after the flood tide into the sea. The inverted siphon system of the sea entrance of the embodiment conveys the flood tide seawater to the sea through the 14 pipelines of the inverted siphon, ensures that the backward flowing seawater smoothly flows back to the sea, and ensures the mobility of the water body. By arranging the physical filter belt 2 and the retaining dam, the quality of the seawater and river water which flow back to the sea is ensured, and the quality of the seawater at the sea mouth is prevented from deteriorating. When the control gate of the inverted siphon 14 is opened, water flows into a gate well, branches and other river garbage are intercepted by the trash rack 12, and manual cleaning is carried out; the seawater enters the inverted siphon 14, flows into the catchment area at the end of the pipeline along the pipeline and finally flows into the sea.
