摘要

家庭、医院和制药工业废水的排放已被确定为环境中药物的主要来源。许多研究侧重于从医院和家庭废水中去除药物。然而，文献中对真实制药废水的处理及其处理后的解毒效果进行评价的研究数量有限。采用响应面法（RSM）评价了光- fenton氧化法处理实际制药废水的效果，并根据处理后的工艺条件对水蚤的毒性进行了评价。在三维图形上读取去除效率，以更清楚地确定最佳条件。采用双氯芬酸（DCF）、大水蚤（Daphnia magna）毒性、总有机碳（TOC）和颜色参数评价光- fenton氧化法处理效果。采用四次公式建立的RSM模型适用于太阳能- fenton氧化法去除制药废水中的TOC和颜色。在pH为2,87,297 g FeSO4/L和4,38 g H2O2/L的最佳条件下，101 min，光- fenton氧化可达到99%的DCF， 94%的TOC和81%的去色效率。此外，原废水的毒性，如20%的LD50值所示，在处理后大大降低，LD50值在应用光- fenton氧化后增加到90%。

Treatment of real pharmaceutical industry wastewater by photo-Fenton oxidation using the response surface methodology, evaluation of diclofenac degradation and toxicity

Discharges from domestic, hospital, and pharmaceutical industry wastewater have been identified as the main sources of pharmaceuticals in the environment. Many studies focused on the removal of pharmaceuticals from hospitals and domestic wastewater. However, the number of studies that evaluated the treatment of real pharmaceutical wastewater and its detoxification after treatment is limited in literature. This study evaluated the treatment of real pharmaceutical wastewater by photo-Fenton oxidation using response surface methodology (RSM) and its toxicity with Daphnia magna according to process conditions after treatment. The removal efficiencies were read on 3D graphics to determine the optimum conditions more clearly. Diclofenac (DCF), Daphnia magna toxicity, total organic carbon (TOC), and color parameters were followed to evaluate the treatment efficiency of the photo-Fenton oxidation. The developed RSM model with the quartic formula was found to be suitable for TOC and color removal from pharmaceutical wastewater by solar photo-Fenton oxidation. At optimum conditions of pH 2,87, 0,297 g FeSO₄/L, and 4,38 g H₂O₂/L for 101 min, >99 % DCF, 94 % TOC, and 81 % color removal efficiencies were achieved by photo-Fenton oxidation. Moreover, the toxicity of the raw wastewater, as indicated by an LD50 value of 20 %, was substantially reduced post-treatment, with the LD50 value increasing to 90 % following the application of photo-Fenton oxidation.
