[0002] As an economical and effective water treatment method, artificial wetlands have been widely used in sewage treatment, water quality improvement or deep purification. In particular, subsurface flow wetlands are favored in wetland projects for their outstanding removal of organic matter and denitrification effects. The control of the water level and water output of subsurface flow wetlands has a significant impact on the treatment effect of wetlands, so controlling the water level and water output of subsurface flow wetlands is crucial to the effective and stable operation of wetlands.

[0003] Liu X et al. used multiple inlet valves and multiple outlet valves to regulate the water level and control the water distribution and discharge of subsurface wetlands (utility model patent: a water distribution, discharge and water level regulation for artificial wetlands, authorization announcement number CN 207142927U); Yin XX et al. used a rotating U-shaped pipe with an automatic control device to automatically control the wetland water level, realizing the automatic water replenishment / pumping of the wetland (utility model patent: wetland outlet water level regulating device, authorization announcement number CN 210981421 U). Zhang X et al. designed a siphon artificial wetland outlet regulating device, which controls the wetland water level by controlling the exhaust and using the siphon principle (invention patent: a domestic sewage artificial wetland outlet regulating device and its use method, application publication number CN117886451 A). However, in many research results on wetland water level regulation and water discharge control, their structures are relatively complex, the operation is cumbersome, and they are prone to operating failures.

[0008] Furthermore, the vertical angle β between the outlet water connecting pipe and the outlet water collecting pipe is controlled within a range of -3° to 3°.

[0009] Furthermore, the sum of (α+β) is controlled within -2°~2°;

[0010] Furthermore, a supporting pier is provided at the bottom of the regulating well body corresponding to the vertical elbow.

[0011] Furthermore, the regulating well body is a facility made of concrete, reinforced concrete, brick, concrete module or steel, plastic or fiberglass.

[0012] Furthermore, the water inlet end of the vertical elbow is connected to the water outlet connecting pipe; the vertical elbow is a 90°, 60°, or 45° elbow; the vertical elbow is made of a steel pipe, a cast iron pipe, a plastic pipe, or a fiberglass pipe.

[0014] Furthermore, two adjacent adjusting short pipes are detachably connected; the detachable connection includes a flange connection, a socket connection, or a threaded connection.

[0015] Furthermore, the length of the short tube is adjusted to 10-50 cm.

[0016] To achieve the above object, a wetland water discharge control method of the present invention is characterized in that the method comprises the following steps:

[0017] Real-time monitoring of wetland water levels;

[0018] When the wetland water level is high (exceeding the wetland design water level or normal operating water level) or the wetland water output needs to be increased, remove the regulating short pipe and lower the top elevation of the regulating short pipe;

[0019] When the wetland water level is low (lower than the wetland design water level or normal operating water level) or the wetland water output needs to be reduced, install an adjusting short pipe to increase the top elevation of the adjusting short pipe.
