In the present work, the degradation of three estrogens (17β-estradiol (E2), estrone (E1) and 17α-ethinylestradiol (EE2)) was investigated under photoactivation of hydrogen peroxide and persulfate. Lab-scale irradiation experiments showed that both UVA and UVB radiations are able to photoactivate the oxidant precursors, although UVB is more efficient to generate radicals and therefore to degrade the targets. The efficiency of both oxidant precursors was investigated showing higher efficiency in the system with persulfate. The pseudo-first order degradation rate constants and the second order rate constants between the hydroxyl or the sulfate radicals and estrogens were measured. In order to evaluate the process efficiency in real treatment conditions, the degradation of the estrogens spiked into sewage treatment plant effluent was studied. Measurements of second order rate constants between the radical and the effluent organic matter by laser flash photolysis allowed to understand the involved quenching mechanisms. A Yeast Estrogen Screen (YES) assay was used to follow the decrease in estrogenic activity during the estrogen degradation. This assay permitted to ensure that the studied processes are not only able to degrade the estrogens but also to remove their estrogenic activity.

Single activation of peroxymonosulfate (PMS) in a homogeneous system is sometimes insufficient for producing reactive oxygen species (ROS) for water treatment applications. In this work, manganese spinel ferrite and graphitic carbon nitride (MnFe 2 O 4 /g-C 3 N 4 ; MnF) were successfully used as an activator for PMS under visible light irradiation to remove the four-mostdetected-hormone-contaminated water under different environmental conditions. The incorporation of g-C 3 N 4 in the nanocomposites led to material enhancements, including increased crystallinity, reduced particle agglomeration, amplified magnetism, improved recyclability, and increased active surface area, thereby facilitating the PMS activation and electron transfer processes. The dominant active radical species included singlet oxygen ( 1 O 2 ) and superoxide anions (O 2•− ), which were more susceptible to the estrogen molecular structure than testosterone due to the higher electron-rich moieties. The self-scavenging effect occurred at high PMS concentrations, whereas elevated constituent ion concentrations can be both inhibitors and promoters due to the generation of secondary radicals. The MnF/PMS/vis system degradation byproducts and possible pathways of 17β-estradiol and 17α-methyltestosterone were identified. The impact of hormone-treated water on Oryza sativa L. seed germination, shoot length, and root length was found to be lower than that of untreated water. However, the viability of both ELT3 and Sertoli TM4 cells was affected only at higher water compositions. Our results confirmed that MnF and visible light could be potential PMS activators due to their superior degradation performance and ability to produce safer treated water.

“…Pretreatment with advanced oxidation processes (AOPs) before DNBF is a possible way to treat this biodegradable wastewater. It is widely known that AOPs are increasingly used for the advanced removal of SEs because of their good oxidation effects, e.g., hydrogen peroxide, persulfate, chlorine, and ozone-based AOPs. − Nevertheless, such techniques often consume a lot of energy and are influenced by the water quality, which limits their application in practice to some extent. In recent years, peracetic acid (PAA) has been widely used as an oxidant for AOPs because of its better oxidizing property and easier generation of free radicals. − UV is the common activation method for PAA due to its wide application and environment friendliness, and UV/PAA has been shown to be more selective in the degradation of antibiotics and other pharmaceuticals, as well as strong disinfection potential. − Our previous study has shown that the UV/PAA process could achieve the efficient degradation of SEs in complex water quality; however, both the total organic carbon (TOC) and acute toxicity increased after the treatment, so further treatment of the effluent was still required .…”

Total nitrogen (TN) and steroid estrogens (SEs) in secondary effluent challenge widely used denitrification biofilter (DNBF) in achieving the regulated limit value in water reuse, as well as toxicity reduction. Herein, we first use UV/peracetic acid (PAA) as a pretreatment of DNBF for advanced wastewater treatment, followed by an evaluation of its effectiveness in removing TN and SEs from low C/N wastewater. The results showed that UV/PAA-biofilter significantly improved the removal of TN and SEs compared to conventional DNBF. Under the conditions of [PAA]0 = 15 mg/L, UV = 1250 μW/cm2, photoreaction time of 30 min, and biofilter hydraulic retention time (HRT) = 3 h, the SE removal rates could reach more than 95% and the effluent TN maintained less than 10 mg/L. Furthermore, UV/PAA-biofilter improved the reduction of estrogenic activity but not of acute toxicity. Increased extracellular polymeric substance (EPS) content and relative abundance of napA gene were observed in DNBF pretreated with UV/PAA, and Azospira was identified as the core microorganism for denitrogenation. Our investigations confirmed the feasibility of the UV/PAA-biofilter to remove SEs and TN simultaneously, highlighting the great potential of its application in the advanced purification of secondary effluent for safe wastewater reuse.
