摘　　要：利用不同浓度臭氧处理黄沙鳖育苗的水体,在水温27(±1)℃条件下,检测水体的水质变化及黄沙鳖生长、成活情况。结果表明:臭氧能显著降解养殖水体中氨氮、亚硝酸盐氮含量,且能提高水体中的溶解氧含量,水质净化效果显著。投放0.1 mg/L臭氧处理的育苗水体,黄沙鳖的平均体重为17.5(±0.34)g,成活率达到91.33%,效果最好。The aquatic water of Trionyx sinensis was treated by different concentrations of ozone,at（27±1）℃,the water quality was detected,and the growth and survival rate of T. sinensis was observed. The results showed that,by different concentrations of ozone,the contents of NO2-N and NH4-N in aquaculture water significantly decreased,and the dissolved oxygen（DO）content increased. After 21 days,in aquatic water treated with 0.1 mg/L ozone,the average weight of T. sinensis was 17.5（±0.16）g,the survival rate reached 91.33%,the effect was obvious.
