摘　　要：实验检测了海水经臭氧处理后COD的变化：随时间的加长，海水的COD逐渐下降，从2.82mg/L降到0.8mg/L约20小时；不同臭氧浓度在海水中的衰减速度不同，且与海水质量有关，水质较好时，臭氧浓度减少速度相对较慢；用两组不同浓度的臭氧处理水培养三种甲壳类幼苗，对幼苗生长、变态有不同的影响，当[O3]=0.82mg/L时放入苗种培养，实验的第二、三组有70％的苗蜕皮、变态，当[O3]=0.47mg/L时放入苗种，则实验结果与对照组一样无变态现象。The COD changes were tested after O3 treatment to salt water.As the time went by,salt water COD gradually declined from 2.82mg/L to 0.8mg/L. Diffrent O3 concerntrations attenuated differently in salt water,and this was correlated with salt water quality.When the water quality was high,the declining velocity was low.We had three experimental groups culturing three different crustacean seedlings with difflrent O3 concerntrations.The growth of the seedlings and their metamorphoses were then observed. 70％of seedlings in No.2 and No.3 groups arrived the phase of ecdysis and metamorphose when [O3]=0.82mg/L. But the results were the same as No.1 group(comparison group)when[O3]=0.047mg/L.
