STUDY ON EFFICIENCY OF AERATION TYPE IN BIOLOGICAL AERATION FILTER ON THE SEWAGE DISPOSAL

摘要：

Aeration is an important factor affecting Biological Aeration Filter, study on the movement law of two-phase flow can propose academic guidance for confirming the oriental type. This paper designed a set of experiment device, simulated velocity field of gas-liquid two-phase flow under different conditions and analyzed result simulated, an ascendant aeration was suggested. An actual sewage disposal experiment was carded out according to the aeration suggested above. The final result indicates when the ratio of water in aeration tank h/w=1, diameter of capillary tubes d =0.6mm and velocity of bubbles v=0.3m/s, the most efficient state appears.
