Ecological retention strips for stormwater outfalls
By designing an ecological retention zone for rainwater outfalls, including retention, purification, sedimentation, and drainage structures, the problems of poor initial rainwater purification and large land occupation have been solved, thereby improving the urban river water ecological environment and meeting flood control requirements.

AI Technical Summary
Existing runoff pollution control technologies have poor initial purification effects on rainwater and require large land areas, which is not conducive to flood control, especially in urban areas where land is scarce.
Design an ecological retention strip for rainwater outfalls, including a retention and purification structure, a retention and sedimentation structure, a front-end sedimentation structure, and a drainage structure. The retention and purification structure performs preliminary purification of rainwater, and the purified water overflows into the retention and sedimentation structure and flows into the downstream river channel. Combined with the riverbank slope structure, the preliminary interception and discharge of rainwater is achieved.
It achieves preliminary purification of rainwater, improves the water ecological environment of urban rivers, reduces the land area required, is suitable for urban waterways where land is scarce, and meets the need for submerged outflow of rainwater.
