| 摘 要： | 为了更准确地评价池塘养殖中主要的三种不同增氧方式的增氧机的性能,通过标准水池试验和养殖池塘中实地试验,研究了三种增氧机的增氧方式在清水试验中的增氧能力、动力效率和养殖池塘中的溶解氧均匀度与水温均匀度的变化。结果表明,曝气式增氧机增氧能力和动力效率最好,增氧能力比水车的高55.1%,动力效率比水车的高出64.0%。增氧能力和动力效率从高到低依次是曝气式、叶轮式和水车式。水车增氧机对养殖池溶解氧的均匀度提升最快,最高的达到46.43%,曝气增氧设备对养殖池溶解氧的均匀度提升达到29.46%；对养殖池水温均匀度的提升,三种增氧机都不是很明显。该研究为在池塘养殖中合理运用不同增氧方式提供了有益的借鉴。

| Abstract: | In order to accurately evaluate the performance of aquaculture ponds in three main aerator aeration mode, through the standard pool experiments and aquaculture ponds in the field test, study three aerator aera- tion aerobic capacity in clean water test, the dissolved oxygen in the pond of power efficiency and uniformity of and the uniformity of water temperature changes. The results show that, the best aeration type aerator aeration capacity and power efficiency, aeration capacity is 55.1% higher than the waterwheel, power efficiency is 64% higher than the waterwheel. Aerobic capacity and the power efficiency of the order from high to low is aerated, the impeller and the waterwheel type. The waterwheel aerator on dissolved oxygen in pond improving uniformity of the fastest, the highest 46.43%, aeration equipment for dissolved oxygen in pond improving uniformity of the highest 29.46%; the breeding pool water temperature uniformity, three kinds of aerator is not very obvious. This study provides a useful reference for the rational use of different aeration methods in pond culture. |
