Sometimes free-living in conventional water treatment processes are not eliminated and cause adverse health effects in water consumer. So, the efficiency of UV lamps (125 W) with irradiation intensity 1020 μW cm on inactivation of free-living released in water samples has been investigated along with the investigation of the effects of turbidity and change of temperature and exposure time in constant of pH 8 ± 0.2. The results showed that UV radiation could disabled the larval and adult after 12 and 15 min in the presence of turbidity 5 NTU, respectively. Also, increased turbidity up to 50 NTU decreased the inactivation efficiency of larval and adult from 100% to 73% and 64%, respectively. In addition, with increased temperature, the inactivation efficiency increased significantly in a short time. The results showed a significant relationship between increasing exposure time and temperature and turbidity reduction with UV radiation efficiency in the inactivation of the (P < 0.00). It was also found that the efficiency of the lamp on larvae was more than the adult . Therefore, UV radiation can well inactivate larvae and then adult free-living in water.
有时，传统水处理工艺中自由生活的[具体生物名称未明确]无法被消除，会对用水者造成不良健康影响。因此，研究了辐照强度为1020 μW/cm的125 W紫外线灯对水样中释放的自由生活的[具体生物名称未明确]的灭活效率，同时研究了在pH值为8±0.2恒定条件下浊度、温度变化和暴露时间的影响。结果表明，在浊度为5 NTU时，紫外线辐射分别在12分钟和15分钟后可使幼虫和成虫失去活性。此外，浊度增加至50 NTU时，幼虫和成虫的灭活效率分别从100%降至73%和64%。另外，随着温度升高，灭活效率在短时间内显著提高。结果表明，在[具体生物名称未明确]的灭活过程中，暴露时间和温度的增加以及浊度的降低与紫外线辐射效率之间存在显著关系（P < 0.00）。还发现该灯对幼虫的效率高于成虫。因此，紫外线辐射能够很好地灭活水中的幼虫，进而灭活成虫自由生活的[具体生物名称未明确]。
