通过实验研究了紫外线照射对两种地表水和两种地下水生物再生潜力的影响。评估紫外线照射前（紫外线照射前）和紫外线照射后（紫外线照射后）的可生物降解溶解有机碳（BDOC）差异。快速（5天）可同化有机碳（AOC）测量用于确定紫外线照射前和照射后水体之间的显著差异，并进行了比较。结果表明，紫外线可能会增加某些地表水的BDOC。一名学生的t检验显示，90%的置信度表明，紫外线照射后，地表水A（SWA）的BDOC增加。所有水的P17 AOC结果显示，在95%以上的置信度下，紫外线照射后的样品大于紫外线照射前的样品，表明紫外线照射后再生潜力增加。 由于在一些测试水域中观察到生物再生潜力增加，考虑添加紫外线消毒的公用事业公司应在安装紫外线之前和之后仔细检查其水源水和分配系统水的再生潜力，以确定二次消毒的效果和调整（如果需要）。

Experiments were conducted to evaluate the effects of UV irradiation on biological regrowth potential of two surface waters and two groundwaters. Biodegradable dissolved organic carbon (BDOC) differences between pre (before UV) and post (after UV) UV were evaluated. Rapid (5 day) assimilable organic carbon (AOC) measurements were used to ascertain a significant difference between pre and post-UV irradiated waters were also compared. Results suggested that UV may increase BDOC for some surface waters. A Student's t-test showed, with 90% confidence, that the BDOC for surface water A (SWA), increased after UV. The P17 AOC results for all the water showed, with greater than 95% confidence, the post-UV samples were greater than the pre-UV samples indicating an increase in regrowth potential after UV irradiation. Since an increase in biological regrowth potential was observed in some of the waters tested, utilities considering the addition of UV disinfection should carefully examine the regrowth potential of their source water(s) and distribution system water(s) before and after UV installation to determine effects and adjustments to secondary disinfection if required.
