AI Technical Summary

Technical Problem

Traditional constructed wetland systems occupy a large area and have limited treatment efficiency, especially in the treatment of large-volume wastewater.

Method used

The wastewater treatment system integrating constructed wetlands and biological contact oxidation includes constructed wetland modules, sedimentation and separation modules, biological contact oxidation modules, filtration and purification modules, and effluent discharge modules. Through modular integrated layout, the biological contact oxidation module is introduced to enhance pollutant removal capacity and reduce the need for wetland area.

Benefits of technology

Without increasing the wetland area, it significantly improves wastewater treatment efficiency and the system's resistance to shock loads, making it suitable for treating large-flow wastewater and possessing high pollutant removal rates and stable operating performance.
