纳米气泡增氧机对拉氏鱥养殖池塘水质的影响

Effect of micronano bubble Oxygenator on water quality in Phoxinus lagowskii breeding Pond

纳米气泡具有表面积大、传质效率高、生物活性强、氧化性强、尺寸小等优点,被广泛应用于水产养殖。该试验在拉氏鱥(Phoxinus lagowskii)养殖池塘中,分别应用相同功率的纳米气泡增氧机与普通增氧机,并在110d内定期监测水质指标。试验结果表明,纳米气泡机组显著提高了鱼池的溶氧含量,且能够起到很好降低水体中有害成分的作用,例如降低氨氮含量0.273mg/L、亚硝酸盐0.2mg/L~0.48mg/L,但对水体温度和盐度无显著影响。该试验对使用普通增氧机和纳米气泡机的池塘进行水质研究,为提高池塘产量提供理论基础。

Nano-bubbles are widely used in aquaculture because of their large surface area,high mass transfer efficiency,strong biological activity,strong oxidation and small size.This experiment was conducted in a Phoxinus lagowskii breeding pond using a nano-bubble and a normal oxygenator with the same power respectively.The water quality indexes were monitored regularly within 110 days.The results showed that the nano-bubble unit significantly increased the dissolved oxygen content of the fish pond,and played a good role in reducing the harmful components in the water,such as ammonia nitrogen content 0.273mg/L,nitrite 0.2mg/L~0.48mg/L,but had no significant effect on the water temperature and salinity.The experiment studied the water quality of the pond using the common oxygen generator and nano bubble machine,and provided the theoretical basis for increasing the pond yield.
