臭氧—紫外线组合系统净化靓巴非蛤(Paphia schnellian)微生物的研究

Using ozone-ultraviolet combination system to purify Paphia schnellian for killing microorganisms

【目的】筛选出净化靓巴非蛤的最优净化方法。【方法】采用臭氧—紫外线组合系统杀菌净化海水,结合非循环开放式方法净化靓巴非蛤微生物,以大肠菌群和菌落总数为指标,分别选取温度、盐度、换水率、贝水比等4个因素3个水平进行正交试验,探讨净化靓巴非蛤的最佳环境条件。【结果】依据正交试验结果及从净化效果和经济角度考虑,确定臭氧—紫外线组合系统净化靓巴非蛤的条件为:温度30℃、盐度35‰、换水率8h/次、贝水比1∶10、净化时间36h。【结论】利用臭氧—紫外线组合系统可达到净化贝类的要求。

[Objective]The present experiment was carried out to screen the best method for killing microorganisms for raising Paphia sehncllian. [ Method ]The ozone-ultraviolet combination system was used to disinfect the sea water and the microorganisms in Paphia schnellian were killed using non-circulating-open method in combination with orthogonal tests. The coliforms and aerobic plate count were used to investigate the best environmental conditions for purification of Paphia schnellian. [Result]The results showed that the best conditions for purification of Paphia schnellian using ozone-ultraviolet combination system were： 30℃ temperature, 35%, salinity, 8 hourly water change, 1：10 shellfish to water ratio, and 36 hours purification time, according to the results of orthogonal test, purification and economic benefits. [Conclusion]The ozone-ultraviolet combination system was found to be economic and effective to purify the Paphia schnellian for killing microorganisms.
