AI Technical Summary
Existing bacterial-algal biofilm systems struggle to balance the simultaneous growth of bacteria and algae and their stable interaction. The uneven distribution of microalgae and bacteria leads to low wastewater treatment efficiency and insufficient resource utilization.
The two-dimensional heterogeneous bacterial and algal biofilm device uses the combination of the tilt angle of the biofilm growth channel and the carrier material to form a driving force of gravity and capillary power, which promotes the heterogeneous distribution of bacteria and microalgae in biofilm thickness and sewage flow direction, thereby realizing the utilization of cascade nutrients and bacterial-algal symbiosis.
It achieves the synergistic growth of bacteria and microalgae, improves wastewater treatment efficiency, reduces energy consumption, enhances resource utilization value, and achieves efficient nitrogen and phosphorus removal and carbon sequestration.
