AI Technical Summary
Existing ecological filter dams can obstruct flood discharge and affect the drainage capacity of rivers during flood season.
Design a modular ecological filter dam, including a concrete base, concrete retaining wall, floating island support rods, and detachable interception device. By installing aquatic plant filtration structure during flood season and using filler box during dry season, flexible adjustments can be made for different seasons to ensure the flood passage capacity of the river and water purification.
During flood season, artificial aquatic plants are used to purify water without affecting the river's flood discharge capacity. During the dry season, they can impound water and absorb pollutants, allowing for flexible adjustments based on seasonal changes. This solves the problem of flood discharge in the river during flood season while maintaining the water purification effect.
