The dispersion of pollutants and proliferation of antibiotic resistant bacteria in the aquatic environment are an emerging health concern worldwide. In this sense, it is essential to develop new technologies to increase the quality of wastewater treatment, which is spread throughout the environment. The present study has demonstrated evidence of the existence of antibiotic and mercury-resistant bacteria in the aquatic environment. The application of heterogeneous photocatalysis with UVA/TiO₂ P25 slurry (200 mg L⁻¹), UVA/TiO₂-immobilized, and UVA/TiO₂-immobilized/H₂O₂ were evaluated for the simultaneous elimination of a mixture of contaminants of emerging concern (acetamiprid (ACP), imazalil (IMZ) and bisphenol A (BPA)) and inactivation of antibiotic- and mercury-resistant bacteria (Pseudomonas aeruginosa and Bacillus subtilis). UVA/TiO₂-immobilized/H₂O₂ increased the inactivation and elimination of the contaminants. After the combined treatment, the mixture of BPA, IMZ and ACP decreased 62%, 21% and <5%, respectively, after 300 min at 13.10 kJ L⁻¹ of accumulated UV energy. The Pseudomonas aeruginosa strain was inactivated after 120 min using 5.24 kJ L⁻¹ of accumulated UV energy, whereas the Bacillus subtilis strain was shown to be extremely resistant, with a capacity to develop mechanisms to avoid the oxidation process.

在水生环境中污染物的扩散和抗药性细菌的扩散是全球范围内对健康日益关注的问题。从这个意义上讲，开发新技术以提高废水处理质量至关重要，因为废水处理质量遍布整个环境。本研究证明了水生环境中存在抗生素和抗汞细菌的证据。UVA / TiO ₂ P25浆料（200 mg L ^-1），固定有UVA / TiO ₂和固定有UVA / TiO ₂ / H ₂ O ₂的非均相光催化的应用评估了同时消除新出现的污染物混合物（扑热息痛（ACP），咪唑（IMZ）和双酚A（BPA））以及灭活抗生素和耐汞细菌（铜绿假单胞菌和枯草芽孢杆菌）的能力。UVA / TiO ₂固定化/ H ₂ O ₂增强了污染物的灭活和消除。联合处理后，在累积UV能量为13.10 kJ L ^-1的情况下，经过300分钟后，BPA，IMZ和ACP的混合物分别降低了62％，21％和<5％。的铜绿假单胞菌菌株是用5.24千焦大号120分钟后失活^-1累积UV能量，而枯草芽孢杆菌菌株显示出极强的抗性，具有开发避免氧化过程的机制的能力。
