Abstract :
This paper researched on the simulated flotation wastewater treatment technology. Experiments were performed by the operating manner of Anaerobic-BAC. Compared with natural photo degradation, the treatment effect of Anaerobic-BAC was obvious. The experimental results show that the biodegradability was greatly improved, the B/C could be increased from 0.09~0.19 to 0.17~0.37. Under this experimental condition, the optimum operation parameters of BAC process were determined as: the activated carbon-water ratio 2:1, air-water ratio 3:1, HRT 4h. After processing, the concentration of COD was lower than 100 mg/L, and the removal efficiency was higher than 70%.
