When the dual liquid level meter 4 detects that the water level in the intercepting well 1 reaches the detection height of the low-level liquid level meter and is higher than the dry season low threshold value set by the liquid level meter on the lower side of the water inlet gate, the dual liquid level meter triggers the sewage pipe 5 to receive the artesian sewage and drains the sewage to a sewage plant by gravity flow; when detecting that the water level in the intercepting well 1 reaches a high threshold value in dry seasons, the dual liquid level meter 4 triggers the submersible sewage pump 12 and a control valve to be opened, and correspondingly pumps sewage in the intercepting well into a sewage pipe network communicated with a sewage plant or pumps initial rainwater in the intercepting well into an artificial wetland through a water outlet B of a first branch or a water outlet C of a second branch of the branch water outlet pipe 9; the dual liquid level meter 4 triggers the submersible sewage pump 12 when detecting that the water level in the intercepting well 1 reaches the high threshold value in rainy season, and directly outputs sewage at the bottom of the intercepting well to the third water outlet D of the intercepting well 1 to be directly discharged into a river channel.
