AI Technical Summary
In algal symbiotic systems, light penetration and irradiation range are limited by the shielding properties of solid materials, leading to instability in the nitrification reaction and making it difficult to scale up in engineering.
A blue light irradiation system for algae and bacteria was adopted. The light intensity was set according to the concentration of solid matter, the ratio of light time to dark time was 16h:8h, the light intensity was 100-3500 Lux, and the concentration of solid matter was 100-3000 mg MLSS/L. The light treatment was carried out through a biological denitrification device.
It ensures full utilization of blue light, inhibits the activity of nitrifying bacteria, promotes the stable accumulation of nitrite, and improves the stability and efficiency of the nitrification reaction, making it suitable for the treatment of low-ammonia wastewater.
