[0002] With the acceleration of urbanization, the treatment of black and smelly water bodies has become a core challenge in water environment management. Due to problems such as direct sewage discharge, sedimentation and eutrophication, urban rivers and lakes have insufficient dissolved oxygen and enriched odorous substances (such as hydrogen sulfide and ammonia nitrogen), forming "black and smelly" surface pollution, which seriously threatens ecological security and residents' health.

[0003] At present, commonly used black and odorous water treatment technologies include physical, chemical, biological and other methods. However, physical treatment technologies such as mechanical dredging and flotation are costly and affect the ecological environment. Chemical treatment technologies such as chemical precipitation and redox methods may introduce new pollutants and pose a risk of secondary pollution. Although biological treatment technologies are effective, they have a long repair cycle and are greatly affected by environmental factors.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

After the pressure limit is reached, the cleaning fluid pushes the sealing plug open, allowing the cleaning fluid to flow into the top block and the cleaning body, thereby exporting the high-pressure cleaning fluid. By replacing springs with different elastic coefficients, the pressure limit value inside the telescopic airbag can be adjusted, thereby adjusting the pressure of the exported cleaning fluid. The pressure adjustment is convenient and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Specifically, a plurality of telescopic airbags 201 are installed in the corresponding placement grooves 103. When the telescopic airbags 201 are not pumped with cleaning fluid through the water pump 207, the telescopic airbags 201 are in a compressed and folded state. At this time, the photocatalytic component 3 connected to the side column 205 is immersed in water to photocatalyze black and smelly water.
