[0002] For modern cities, waterways are a vital element in maintaining urban ecological balance. However, with rapid urbanization, waterways have suffered from unprecedented pollution. The causes of waterway pollution include the discharge of domestic and industrial wastewater, illegal dumping of hazardous waste, and other factors. Severe pollution damages aquatic ecosystems and threatens the lives and health of residents along the riverbanks.

[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN215559267U discloses a microbial carrier river purification system, which uses a water intake device to provide power to send river water upstream to the microbial carrier purification device for purification. During the purification process, the operation of the water intake device not only consumes a lot of electricity, but also generates a lot of noise.

[0004] Therefore, it is necessary to design a river pollution bypass diversion purification system that can divert polluted river water into a bypass channel without power, thereby reducing power consumption and operating noise, in order to solve the current technical problems. Summary of the Invention

A controllable dam is set in the main river between the inlet end and the outlet end, and an aquatic plant planting area is set in front of or behind the controllable dam. An artificial wetland purification module is set in the bypass river. The artificial wetland purification module has a pretreatment zone, an oxidation zone, a purification zone, and a stabilization zone arranged sequentially along the water flow direction of the bypass river. The pretreatment zone is used for coarse filtration and sedimentation of large particles. The oxidation zone is used for degradation of organic matter. The purification zone is used for adsorbing pollutants. The stabilization zone is used to simulate a natural wetland and enhance the self-purification capacity of the water body.

[0007] Furthermore, the pretreatment zone is a first packing zone with a packing particle size of 30-80 mm.
