The device can ensure the interception of sewage under the condition that deep foundation pit excavation cannot be performed and large disturbance construction is performed.
As a preferred embodiment of the river sewage interception device of the present invention, fig. 2 is a schematic connection diagram of the soft enclosure and the filtering enclosure of the river sewage interception device of the present invention. Fig. 3 is an exploded view of the connection of the soft enclosure and the filtering enclosure of the river sewage treatment apparatus of the present invention. As shown in fig. 1 to 3, one end of the filtering enclosure 30 is formed with a vertical groove 70, two opposite ends of the soft enclosure 20 are provided with protrusions 71, and the protrusions 71 are inserted into the grooves 70 and can slide up and down to realize sliding connection between the filtering enclosure 30 and the soft enclosure 20. The sliding arrangement of the soft enclosure 20 and the filtering enclosure 30, which can move up and down, is used for ensuring that the soft enclosure 20 can move up and down along with the lifting of the water level.
As a preferred embodiment of the river sewage interception device of the present invention, referring to fig. 4, a longitudinal cross-sectional view of the river sewage interception device of the present invention is shown. Fig. 5 is a transverse cross-sectional view of the river sewage interception device of the present invention.

The buoyancy structure 22 is a plurality of floating balls floating on the river surface. In this embodiment, the size of the soft enclosure 20 is selected to be not lower than the river maximum water level by calculating the river maximum water level. The filling bag 21 is elongated and is disposed along the river course. Multiple small size fill bags 21 of equal length may also be used in spaced apart relation.
Because a plurality of sewage discharge sources are arranged along the river, the enclosure frame formed by combining the soft enclosure 20 and the filtering enclosure 30 can be arranged in the river at certain intervals.

The soft enclosure is made of watertight materials, and the top of the soft enclosure is provided with a floating ball for connection so as to float up and down along with the water level; the bottom of the soft enclosure is additionally provided with a filling bag which can be filled with stones and the like and is used for preventing the soft enclosure from floating upwards.
A fixed steel pipe is vertically arranged every 10m, and the fixed steel pipe is connected with the soft enclosure through a ring buckle so as to ensure that the soft enclosure does not change too much along with water flow. And when the water level is high, the river sewage is discharged between the soft enclosing wall and the river bank, and the river water in the river is isolated from the sewage through the soft enclosing wall and the filtering enclosing wall 30, so that the sewage is prevented from polluting the river water.
The top of the filter enclosure 30 is not lower than the top of the soft enclosure 20. In this embodiment, the top of the filter enclosure 30 is flush with the top of the soft enclosure 20. The filtering fence 30 is permeable, so that water flow can freely enter and exit the filtering fence 30, but pollutants in sewage in the soft fence cannot pass through the filtering fence 30 to play a role in filtering the sewage, and the soft fence and the river bank are combined to form a sewage discharge area along the river and the water level of the river are balanced with each other.
