The disinfection of synthetic fresh-cut wastewater (SFCWW) by several solar processes has been investigated as an alternative to the commonly used chlorination in this industry. To this end, a SFCWW recipe was developed based on real sample analysis from the fresh-cut industry and literature data. It is characterized mainly by the presence of organic matter in solution (25 mg/L DOC) and turbidity (100 NTU). The inactivation kinetics of human pathogenic bacteria (E. coli O157:H7 and Salmonella enteritidis) in SFCWW was assessed by solar photo-inactivation, H₂O₂/solar, iron/solar and solar photo-Fenton processes. Excellent inactivation performance was achieved in all cases demonstrating the capability of solar processes to disinfect water even at high levels of turbidity. The best bacterial inactivation rates were obtained with the H₂O₂/solar process (20 mg/L) in less than 60 min for both E. coli and S. enteriditis. Moreover, the influence of UVA irradiance (10–50 W/m²) on the inactivation of both pathogens by the H₂O₂/solar process at several H₂O₂ concentrations was investigated. These results showed a slightly different response for both pathogens against UVA irradiance and H₂O₂ concentration: photo-limitation for both types of bacteria; while only E. coli was limited by the H₂O₂ concentrations investigated in this work.

已经研究了通过几种太阳能工艺对合成鲜切废水（SFCWW）进行消毒的方法，以替代该行业中常用的氯化方法。为此，根据来自鲜切行业的真实样本分析和文献数据，开发了SFCWW配方。它的主要特征是溶液中有机物的存在（25 mg / L DOC）和浊度（100 NTU）。通过太阳光灭活H ₂ O ₂评估了SFCWW中人类病原菌（大肠杆菌O157：H7和肠炎沙门氏菌）的灭活动力学。/太阳能，铁/太阳能和太阳光电芬顿工艺。在所有情况下均具有出色的灭活性能，这表明即使在高浊度下，太阳能工艺也具有对水进行消毒的能力。对于大肠杆菌和肠炎沙门氏菌，用H ₂ O ₂ /太阳能法（20 mg / L）在不到60分钟的时间内可获得最佳的细菌灭活率。此外，UVA辐照度（10–50 W / m ²）对在数个H ₂ O _2下通过H ₂ O ₂ /太阳过程使两种病原体失活的影响研究浓度。这些结果表明，两种病原体对UVA辐照度和H ₂ O ₂浓度的反应略有不同：两种细菌的​​光限制；而只有大肠杆菌受到本文研究的H ₂ O ₂浓度的限制。
