采用过氧乙酸（PAA）和紫外线（UV）单独消毒法以及PAA/UV组合消毒法对水（合成）和生活污水进行消毒，以验证这些高级氧化工艺对粪便污染物E.大肠杆菌、总大肠菌群（在生活污水的情况下）和大肠杆菌（如病毒指示剂）。在所研究的实验条件下，PAA的剂量为2、3和4 mg/L，接触时间为10 min，暴露于UV辐射60和90 s，结果表明，与单独的消毒方法相比，PAA/UV组合方法提供了优越的上级功效。
The individual methods of disinfection peracetic acid (PAA) and UV radiation and combined process PAA/UV in water (synthetic) and sanitary wastewater were employed to verify the individual and combined action of these advanced oxidative processes on the effectiveness of inactivation of microorganisms indicators of fecal contamination E. coli, total coliforms (in the case of sanitary wastewater), and coliphages (such as virus indicators). Under the experimental conditions investigated, doses of 2, 3, and 4 mg/L of PAA and contact time of 10 minutes and 60 and 90 s exposure to UV radiation, the results indicated that the combined method PAA/UV provided superior efficacy when compared to individual methods of disinfection.
