“…Although only 43% of TMP was removed with PMS/UV-C, this was the most efficient of all the studied treatments. The application of SR-AOPs and HR-AOPs to remove ABs in water has been successfully demonstrated by several authors (Khan et al, 2013;Yin et al, 2018aYin et al, , 2018bFeng et al, 2018;Ji et al, 2014;Ding et al, 2017;Matzek et al, 2017;Feng et al, 2015;Pi et al, 2014;Epold et al, 2015). However, in all those studies, the application of treatments was developed at lab-scale, using high-quality water matrix spiked with ABs.…”

This research reports for the first time the full-scale application of different homogeneous Advanced Oxidation Processes (AOPs) (H 2 O 2 /UV-C, PMS/UV-C and PMS/Fe(II)/UV-C) for the removal of antibiotics (ABs) and antibiotic resistance genes (ARGs) from wastewater effluent at Estiviel wastewater treatment plant (WWTP) (Toledo, Spain). AOPs based on the photolytic decomposition of H 2 O 2 and peroxymonosulfate tested at low dosages (0.05-0.5 mM) and with very low UV-C contact time (4-18 s) demonstrated to be more efficient than UV-C radiation alone on the removal of the analyzed ABs. PMS (0.5 mM) combined with UV-C (7 s contact time) was the most efficient treatment in terms of AB removal: 7 out of 10 ABs detected in the wastewater were removed more efficiently than using the other oxidants. In terms of ARGs removal efficiency, H 2 O 2 /UV-C seemed the most efficient treatment, although PMS/UV-C and PMS/Fe(II)/UV-C were supposed to generate higher concentrations of free radicals. The results show that treatments with the highest removal of ABs and ARGs did not coincide, which could be attributed to the competition between DNA and oxidants in the absorption of UV photons, reducing the direct photolysis of the DNA. Whereas the photolytic ABs removal is improved by the generation of hydroxyl and sulfate radicals, the opposite behavior occurs in the case of ARGs. These results suggest that a compromise between ABs and ARGs removal must be achieved in order to optimize wastewater treatment processes.

Biomasses are very important natural products. Transferring biomass into catalysts for the advanced oxidation process (AOP) via heat treatment has attracted extensive attention. This review systematically introduces and summarizes two kinds of innovative biomass‐based catalysts according to the treating temperature. At low temperature (<300 °C), biomasses are converted into hydrothermal carbonation carbon (HTCC) with semiconductive properties for photocatalysis application. At high temperature (>300 °C), by contrast, the products lose their semiconductive nature and become a conductive carbon‐based conductor (biochar). They usually work as AOP catalysts by activating oxidant of O2, H2O2, and peroxysulfate for environmental treatment. This review summarizes and compares HTCC and biochar according to their formation process, structure, catalytic mechanism, and key points for the activity enhancement. The active units in HTCC are the sp2‐hybridized polyfuran unit while those in biochar are the persistent free radicals, nitrogen‐containing unit, or defects. HTCC converts water into OH radicals by using the photoexcited electron/hole pairs induced by solar illumination, while biochar activates oxidants via the active unit on its surface. More importantly, this review summarizes and demonstrates the key points to obtain high‐efficiency HTCC and biochar catalysts. Finally, conclusions are drawn and the future aspects for biomass‐based catalysis are given.

“…In particular, more than 10 types of SAs have been detected with high concentrations in various environment mediums including water, sediment, and soil (Dong et al, 2016;Song et al, 2018;Verlicchi et al, 2012). Moreover, the adverse effects of SAs such as toxicity to organisms, drug resistance increase, and the production of resistant genes have been reported to pose a threat to the ecological environment and human health (Batista et al, 2016;Yin et al, 2018). In addition, SAs can persist in the environment for a long time because of its poor biodegradability and low removal efficiency by the conventional treatments (Batista et al, 2016;Yin et al, 2018).…”

effect. Radical scavenger experiments indicated that hydroxyl radicals (HO • ) are prevailing active species responsible for SMP removal in UV/Co(II)/PMS system. The degradation of SMP in UV/Co(II)/PMS system was accomplished mainly by hydroxylation of the aromatic ring, extrusion of SO 2 , oxidation of NH 2 group, and N − S bond cleavage. Eight intermediates for SMP degradation were identified, and their toxicities to aquatic organisms were predicted by using the ECOSAR program based on the structure − activity relationships (SARs), which suggested that the chronic toxicities of SMP and its degradation intermediates are more significant than their acute toxicities. The present research indicates that UV/Co(II)/ PMS system is applicable for SMP degradation in aqueous solutions and may be helpful to understand the transformation behavior of SAs.
