【摘要】：目的研究海水淡化饮用水遗传毒性总体水平,评估长期饮用海水淡化水的安全性。方法于2011年12月—2012年9月采集浙江嵊泗县菜园镇海水原水、海水淡化厂各工艺出水18份,地表水原水和各工艺出水5份,按照ISO-13829推荐的国际标准方法进行SOS/umu测试,检测与比较不同水样遗传毒性的相对强弱及遗传毒性生成潜势。结果经海水淡化水厂各工艺的逐步处理,水样的遗传毒性逐渐下降,反渗透出水遗传毒性最低,进一步加二氧化氯消毒后出厂,遗传毒性会有一定程度的提高,其遗传毒性生成潜势高于实际水样的遗传毒性,趋势与实际水样相同。结论海水淡化水的处理工艺对具有遗传毒性的物质有良好的去除作用,海水淡化饮用水的遗传毒性明显低于以地表水为水源的饮用水。
[Abstract]:Objective to study the general level of genetic toxicity of seawater desalination drinking water and to evaluate the safety of drinking seawater desalination water for a long time. Methods from December 2011 to September 2012, raw seawater water was collected from Caiyuan Town, Shengsi County, Zhejiang Province, and 18 effluent samples were obtained from each process of seawater desalination plant. Surface water raw water and 5 parts of effluent from each process were tested by SOS/umu according to the international standard method recommended by ISO-13829. The genotoxicity of different water samples was detected and compared with the potential of genetic toxicity. Results after the treatment of seawater desalination plants, the genotoxicity of water samples decreased gradually, and the genetic toxicity of reverse osmosis effluent was the lowest. After further disinfection with chlorine dioxide, the genotoxicity will be improved to a certain extent, and the potential of genetic toxicity will be higher than that of the actual water sample. Conclusion the treatment process of seawater desalination has a good effect on the removal of genotoxic substances, and the genotoxicity of seawater desalination drinking water is obviously lower than that of drinking water with surface water as its source.
