Abstract Previous studies reported microplastics (MPs), antibiotics, and antibiotic resistance genes (ARGs) in wastewater treatment plants (WWTPs). There is still a lack of research progress on the origin, fate, impact hazards MPs ARGs WWTPs. This paper fills gap this regard. In our search, we used “microplastics”, “antibiotic genes”, “wastewater plant” as topic terms Web Science, checking returned results for relevance by examining titles abstracts. study mainly explores following points: (1) origins fate MPs, antibiotics WWTPs; (2) mechanisms action sludge biochemical pools; (3) impacts WWTPs spread ARGs; (4) harm inflicted environment human body. Contaminants sewage such ARGs, antibiotic-resistant bacteria enter soil water. can travel through food chain thus reach humans, leading to increased illness, hospitalization, even mortality. will enhance understanding among they inflict

ACS ES&T Engineering, Journal Year: 2023, Volume and Issue: 4(1), P. 19 - 46

Published: Aug. 14, 2023

Persulfate based advanced oxidation processes (PS-AOPs) have been regarded as a mainstream degradation technology of organic compounds due to their high efficiency in wastewater treatment. In particular, peroxymonosulfate (PMS) has unique structure and chemical properties, which can be efficiently activated by Co-based catalysts produce active species with potential. These usually determine the subsequent an efficient process, while intrinsic reaction mechanism behind this complex process remains unclear therefore impedes continual development scientific community. Recently, density functional theory (DFT) calculations emerged powerful means identify electronic properties distinguish energy changes PMS activation system. With assistance quantum calculation, increasing investigations conducted focusing on explaining phenomenon that occurred experiments. However, these mainly contributed part sometimes even differ from each other, lacking comprehensive summary DFT calculation results. review, we introduce main uses catalytic PMS, provide recent application examples heterogeneous different structures, then discuss detail. Finally, research results method field are summarized, future focus challenges put forward, is conducive guiding practical design further PS-AOPs creating value products.

The fast rise of organic pollution has posed severe health risks to human beings and toxic issues ecosystems. Proper disposal toward these contaminants is significant maintain a green sustainable development. Among various techniques for environmental remediation, advanced oxidation processes (AOPs) can non-selectively oxidize mineralize into CO2, H2O, inorganic salts using free radicals that are generated from the activation oxidants, such as persulfate, H2O2, O2, peracetic acid, periodate, percarbonate, etc., while oxidants catalysts via Fenton-type reactions crucial production reactive oxygen species (ROS), i.e., •OH, •SO4-, •O2-, •O3CCH3, •O2CCH3, •IO3, •CO3-, 1O2. Nanoscale zero-valent iron (nZVI), with core Fe0 performs sustained effect in AOPs by gradually releasing ferrous ions, been demonstrated cost-effective, high reactivity, easy recovery, recycling, environmentally friendly heterogeneous catalyst AOPs. combination nZVI AOPs, providing an appropriate way complete degradation pollutants indiscriminate ROS, emerging important technique remediation received considerable attention last decade. following review comprises short survey most recent reports applications participating their mechanisms, future prospects. It contains six sections, introduction theme, hydrogen peroxide, oxygen, other oxidants-based catalyzed nZVI, conclusions about reported research perspectives developments. Elucidation mechanisms nZVI-based may not only pave more affordable AOP protocols, but also promote exploration fabrication effective materials applicable practical applications.
