“…Many studies in a laboratory scale have demonstrated that ionizing radiation can remove recalcitrant organic pollutants in the wastewater via the direct action of high energy and the indirect action of reactive species produced by the radiolysis of water molecules (dominant). ,, In addition to laboratory studies, our research group has established full-scale application projects of industrial wastewater treatment including the advanced treatment unit of electron beam irradiation. The long-term operation data showed stable removal capacity of COD at a competitive treatment cost. , …”

“…The long-term operation data showed stable removal capacity of COD at a competitive treatment cost. 14,15 For example, we established a project of dyeing wastewater using electron beam technology in a capacity of 30,000 m 3 /day in Jiangmen City, Guangdong Province, China in June 2020. The effluent COD was in the range of 20−50 mg/L when the influent COD ranged from 180 to 280 mg/L, and the color decreased about 10 times.…”

The combination of ionizing radiation with the conventional wastewater treatment process could be a way to decrease the adsorbed dose and to simultaneously enhance the removal capacity.…”

Advanced treatment of industrial wastewater is a tough problem in the field of wastewater treatment, and the current advanced treatment processes have some drawbacks, so it is urgent to develop a novel advanced treatment process. In this study, ionizing radiation (electron beam) coupled to the reverse osmosis (IR&RO) process was first developed to treat the effluent of the biologically treated coking wastewater. The results showed that the pretreatment of the biologically treated coking wastewater by ionizing radiation at 2 kGy could simultaneously mitigate the roughness of the RO membrane and obtain a superior chemical oxygen demand (COD) removal effect, in which the maximum membrane flux was found, and the effluent COD of the RO process was 8 mg/L, which is much lower than that obtained by the pretreatment of Fenton and ozone oxidation. Although the addition of H 2 O 2 could increase the treatment capacity of ionizing radiation, the ionizing radiation with H 2 O 2 had no promotion on the performance of the RO process in terms of COD removal. Moreover, compared to sole ionizing radiation, the combination of ionizing radiation with H 2 O 2 increased the roughness of the RO membrane. The results of excitation−emission matrix spectroscopy and Fourier transform infrared spectrum showed that ionizing radiation could regulate the type of intermediate products of organic pollutants in the biologically treated coking wastewater, which further regulates the performance of the RO process. In summary, this study first proved that the IR&RO process can be used as an effective advanced treatment process for industrial wastewater.

During the coronavirus disease 2019 (COVID‐19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), viral transport, fate, disinfection and environmental release in wastewater treatment plants have been issues of high importance for overall management. Although a huge number of scientific publications related to coronaviruses have been published, the number of studies on different aspects of wastewater treatment strategies to deal with SARS‐CoV‐2 abatement is still relatively limited and results are often confusing. To define real wastewater risks for public health and the environment, we have performed a systematic review and identified 96 papers from the PubMed database. We focused on SARS‐CoV‐2 wastewater treatments and how the type and level of treatments affect the virological quality of the effluents, the role of disinfectants, the treatment of medical wastewater, the role of new technologies, as well as the wastewater treatment in low‐ and middle‐income countries. It was concluded that, in general, well‐designed and well‐functioning wastewater treatment plants (WWTPs) and on‐site reliable sanitation systems may significantly limit the risk of SARS‐CoV‐2. The development of cost‐effective decentralized water and wastewater treatment facilities for low‐ and middle‐income countries for the abatement of coronaviruses should be enhanced. Lessons learned during the COVID‐19 pandemic with regard to wastewater treatment are expected to support an improved detection, response and containment of future viral disease outbreaks. © 2023 The Authors.
