摘　　要：本文根据理论分析并结合实验,提出了生物接触氧化预处理微污染原水的气水比的计算公式和有关系数的取值范围;分析了影响气水比的主要因素.Based on theoretical analysis and experimental results the authors put forward an equation to calculate the air/water ratio in pretreatment of low level polluted raw water by submerged bio-film contact oxidation process and also proposed the magnitudes of related parameters. Moreover the range of air/water ratio, major effecting factors and some problems of design are discussed in this paper.
