摘　　要：随着水产养殖产业的持续升温、养殖密度的提高和高产高效养殖技术的推广,增氧装备越来越成为水产养殖必不可少的设备。鼓风曝气系统中的微孔曝气式增氧机因其曝气效率相对较高,适应性较强而广泛应用于水产养殖中。为了更好地了解和推广使用微孔曝气增氧系统,本文通过室内模型试验及数据分析,研究了曝气流量与曝气管长度对总氧体积传质系数的影响,构建了总氧体积传质系数预测模型。因此,本文的研究能为微孔曝气增氧系统在实际中的应用提供有价值的参考。With the aquaculture industry continuing to be favored,the stocking density increasing,and thetechniques to get high yield and high efficiency being popularized,the aeration equipments are becoming in-creasingly essential in aquaculture ponds. Fine bubble aeration system（FBAS） has been widely used inaquaculture ponds to increase dissolved oxygen（DO） concentration and promote water circulation becauseits aeration efficiency is higher and suitability is much stronger compared to other aeration equipments. Inorder to understand and popularize the FBAS,a series of laboratory tests were conducted. The effects ofaeration flow rate and length of aeration pips on total volumetric oxygen mass transfer coefficients were ana-lyzed and then a prediction model for the total volumetric oxygen mass transfer coefficient was developed.The results would provide valuable reference for practical applications of FBAS in aquaculture ponds.
