The multiple branch pipes on the inlet pipe 1, each with multiple water distribution ports 100, can effectively slow down the water flow velocity, which is beneficial to improving the pollutant removal efficiency, reducing the impact of water flow on the wetland ecosystem, avoiding physical damage to organisms in the wetland, and facilitating the reproduction of organisms in the wetland.
[0018] In the embodiment, the water collecting device comprises a water collecting pipe 2, a water outlet pipe 3, a pipeline backwashing assembly 5 and a sewage pipe 4. The water collecting pipe 2 is connected with the water outlet pipe 3 perpendicularly. One end of the water outlet pipe 3 penetrates through a water outlet 301 and extends into a water collecting pool 11. The pipeline backwashing assembly 5 is arranged at the connection between the water collecting pipe 2 and the water outlet pipe 3. A sewage outlet 401 is further arranged on the water collecting pool 10. One end of the pipeline backwashing assembly 5 is connected with the sewage outlet 401 through the sewage pipe 4. The pipeline backwashing assembly 5 can backwash the water collecting pipe 2 and discharge the backwashing sewage through the sewage pipe 4. A plurality of water collecting holes are arranged on the water collecting pipe 2. The water bodies infiltrated into the second substrate layer 6 and the third substrate layer 8 are collected through the water collecting holes.
[0019] In the embodiment, the pipeline backwashing assembly 5 comprises a water inlet valve 5.1, a backwashing filter 5.2, a water outlet valve 5.3, a check valve 5.4 and a bypass valve 5.5. One end of the water collecting pipe 2 is sequentially connected with the water inlet valve 5.1, the backwashing filter 5.2, the water outlet valve 5.3 and the check valve 5.4 and connected with one end of the water outlet pipe 3.

[0020] Working principle: In use, the water bodies enter the purification pool 10 through the water distribution openings 100 of the branch pipe in a T-shaped distribution from the branch pipe through the water inlet pipe 1, then enter the water collecting pipe 2 through the first substrate layer 6, the second substrate layer 7 and the third substrate layer 8, and finally flow into the water collecting pool 11 through the water outlet pipe 3.
[0021] The design of the bifurcated water distribution mode in the application can form different water flow speeds and depths to provide suitable living environments for different kinds of organisms, thereby increasing the types and quantities of wetland organisms. The plurality of water distribution openings 100 arranged on the branch pipe in a T-shaped distribution can make the water bodies uniformly distributed in the purification pool 10 and effectively slow down the water flow speed, which is beneficial to improving the pollutant removal efficiency, reducing the impact of the water flow on the wetland ecological system and avoiding physical damage to the organisms in the wetland and facilitating the reproduction of the organisms in the wetland. The water bodies enter the water collecting pipe 2 after passing through the first substrate layer 6, the second substrate layer 7 and the third substrate layer 8. The water collecting pipe 2 can collect the purified water bodies. The pipeline backwashing assembly 5 is arranged to periodically backwash the water collecting pipe 2, thereby preventing the water collecting pool 10 from being blocked.
