[0002] With the acceleration of urbanization, urban sewer systems are becoming increasingly complex. Sewage wells, as an important part of the sewer system, are responsible for collecting and discharging urban domestic sewage and rainwater. However, due to various reasons, such as the accumulation of garbage, silt, etc., sewage wells are prone to blockage, resulting in poor operation of the sewer system and even causing environmental problems such as urban waterlogging.
