摘要

在某些情况下,传统污水处理厂处理的污染废水的质量不足以达到所需的纯度。药物经常在水生环境中被识别,因为它们不断地从污水处理厂释放出来。因此,近年来,它们被列为伪持久性污染物,被认为对公众健康和环境有潜在危害。本研究的重点是利用自然光照下的顺序生物光催化(TiO2/Na2S2O8)处理技术,从废水水溶液中去除3种降压药物(呋塞米、厄贝沙坦和缬沙坦)。采用固相萃取法(SPE)从水中分离药物残留,并采用HPLC-QqQ-MS2进行分析。厄贝沙坦和呋塞米的生物降解率分别大于65%和70%,而缬沙坦的生物降解率为96%。接下来,应用光催化处理,只需200 kJ - m-2即可从流出物中去除90%的微污染物残留物。因此,生物处理与太阳非均相光催化的耦合是一种有价值的脱毒污染废水的手段。

Reclamation of wastewater polluted with antihypertensive drug residues by the biological+solar-photocatalytic sequential treatment plant
The quality of polluted wastewater processed by conventional Wastewater Treatment Plants (WWTPs) is in some cases insufficient to reach the degree of purity required. Pharmaceuticals are frequently identified in the aquatic environment, owing to their constant release from WWTPs. Thus, in recent years, they are cataloged as pseudo-persistent pollutants having been recognized as potentially harmful to public health and environmental concern. This work has focused on the removal of 3 antihypertensive pharmaceuticals (furosemide, irbesartan, and valsartan) from aqueous waste solutions using a sequential biological-photocatalytic (TiO2/Na2S2O8) treatment under natural sunlight. Pharmaceutical residues were isolated from water by solid phase extraction (SPE) and analyzed by HPLC-QqQ-MS2. Biodegradation was greater than 65% and 70% for irbesartan and furosemide, respectively, while valsartan was highly biodegradable (> 96%). Next, photocatalytic treatment was applied and just 200 kJ m-2 was required to remove 90 % of micropollutants residues from the effluent. Therefore, the coupling of biological treatment to solar heterogeneous photocatalysis constitutes a valuable instrument to detoxify polluted wastewater.
