The effect of pH adjusted by aeration with carbon dioxide (CO(2)) on the growth of two species of blue-green algae, Microcystis aeruginosa and Anabaena spiroides, was investigated. Three conditions (pH 5.5, 6.0 and 6.5) were found to have significant inhibitory effects on the growth of the two algae species when acidification treatment was conducted during the logarithmic phase. Differences in the inhibition effect of acidification existed between the two species algae. The tolerance of M. aeruginosa to these conditions was also investigated. The results indicated that M. aeruginosa was inhibited significantly, but not dead at pH 6.5, whereas death occurred at pH 5.5 and 6.0. The greatest inhibitory effect of acidification treatment conducted during the stable breeding phase of M. aeruginosa occurred at pH 5.5, while no inhibitory effect was found at pH 6.5.
通过通气向水中充入二氧化碳（CO2）以调节 pH 值对两种蓝藻（铜绿微囊藻和鱼腥藻）生长的影响进行了研究。在对数生长期进行酸化处理时，发现 3 种条件（pH 值 5.5、6.0 和 6.5）对两种藻类的生长有显著的抑制作用。两种藻类对酸化的抑制效果存在差异。还对铜绿微囊藻对这些条件的耐受性进行了研究。结果表明，铜绿微囊藻在 pH 值 6.5 时受到显著抑制，但没有死亡，而在 pH 值 5.5 和 6.0 时则死亡。在铜绿微囊藻的稳定繁殖阶段进行酸化处理的最大抑制效果出现在 pH 值 5.5，而在 pH 值 6.5 时则没有抑制作用。
