[0002] Wetland treatment is a land treatment process that involves discharging wastewater into marshy areas where the soil is frequently saturated with water and where water-tolerant plants grow. The wastewater flows in a certain direction, and the combined action of the water-tolerant plants and the soil purifies the wastewater.
[0003] To improve efficiency, constructed wetlands use auxiliary flocculation devices to pre-sediment wastewater through physicochemical methods before it enters the wetland. During the flocculation and sedimentation process inside the equipment, the sediment settles at the lowest point inside the equipment due to gravity. However, excessive stirring intensity can cause the bottom flocculation to break up, affecting the flocculation effect.
[0004] There is an urgent need for a flocculation and sedimentation device for wetland treatment to address the technical deficiencies mentioned above. Utility Model Content
