Aeration rate,pore diameter and water depth are the three important factors that affect the performance of microporous aeration. The effects of aeration rate,aperture and water depth on the total mass transfer coefficient of oxy-gen,oxygen availability and theoretical kinetic efficiency are studies and tested. Besides ,the most appropriate pa-rameter combination has been optimized through curves analysis. The results show that the best oxygenation perfor-mance is obtained,when the aerator whose aperture is 200μm,water depth 2.0 m and aeration rate 0.5 m3/h.
