检测了不同浓度臭氧残留对南美白对虾、鲤鱼、鲫鱼、草鱼、武昌鱼、花、白鲢鱼、斑点叉尾鮰存活率的影响。结果表明,虾的耐受力要比鱼类强,虾在臭氧浓度≥1.0mg/L时,可存活至少48h,而鱼类在此浓度下3h后,即出现鳃部充血肿胀、呼吸频率加快等不适应现象,48hLC50为0.13mg/L。如果能正确控制臭氧的残留量,利用臭氧净化养殖用水是水质消毒净化的好方法。
The effects of different concentrations of ozone residues on the survival rate of P. vannamei, carp, crucian carp, grass carp, Wuchang fish, flower, silver carp and I. The results showed that the tolerance of shrimp was stronger than that of fish, shrimp could survive at least 48h when the ozone concentration was above 1.0mg / L, and the gills were swollen and the respiratory rate accelerated after 3h And so does not adapt to the phenomenon, 48hLC50 0.13mg / L. If we can correctly control the residual amount of ozone, the use of ozone purification aquaculture water disinfection and purification is a good way.
