AI Technical Summary
In existing combined sewer systems, traditional reoxygenation equipment has an oxygen utilization rate of less than 15%, and microorganisms are lost with rainwater, requiring repeated additions, making it difficult to achieve stable and efficient removal of pollutants from the discharge outlet.
The reoxygenation device delivers oxygen-enriched water to the lake treatment area. Combined with ecological floating islands and nutrient supply devices, it provides growth space and nutrients for the microbial community, increasing the growth rate and retention rate of microorganisms, thus forming a highly efficient purification system.
It has achieved stable and efficient removal of pollutants from discharge outlets, increased dissolved oxygen content and microbial retention rate in the lake water treatment area, reduced nitrogen and phosphorus nutrients and organic pollutants, and prevented eutrophication of the water body.
