Description

Technical Field

[0002] At present, the existing technologies for managing river shallow wetlands mainly include ex situ management technology and in situ management technology. Ex situ management technology includes: establishing an ecological pond or integrated treatment facility near the river, transporting the river water to the ecological pond or integrated treatment facility through a lifting pump, and returning the effluent to the river, thereby reducing the concentration of pollutants in the river and stabilizing the water quality of the river. However, this technology requires the occupation of land on the shore and is limited by the amount of water in the river, so the investment and operating costs are relatively high. In situ management technology includes: setting up ecological floating islands or aeration equipment in the shallow wetlands in the river. The ecological floating islands float on the water surface, and the water purification effect is limited and the anti-interference ability is poor; the aeration equipment needs to be powered by an external power supply, the energy consumption is high, and the position is relatively fixed, which is not suitable for the long-term purification and stabilization requirements of the water quality of the river shallows. In view of this, in-depth research on the above issues has led to the creation of this case. Utility Model Content
