Application Progress of O3/UV Advanced Oxidation Technology in the Treatment of Organic Pollutants in Water

Abstract

Organic pollution is a significant challenge in environmental protection, especially the discharge of refractory organic pollutants in chemical production and domestic use. The biological treatment method of traditional sewage treatment plants cannot degrade such pollutants, which leads to the continuous transfer of these pollutants into the water environment. Therefore, it is necessary to study clean and efficient advanced treatment technologies to degrade organic pollutants. The ozone/UV advanced oxidation process (O3/UV) has attracted extensive attention. This paper summarizes the reaction mechanism of O3/UV and analyzes its application progress in industrial wastewater, trace polluted organic matter and drinking water. The existing research results show that this technology has an excellent performance in the degradation of organic pollutants and has the characteristics of clean and environmental protection. In addition, the control of bromate formation and its economy is evaluated, and its operating characteristics and current application scope are summarized, which has a practical reference value for the follow-up in-depth study of the O3/UV process.

Analysis of the Applications of Particle Swarm Optimization and Genetic Algorithms on Reaction Kinetics: A Prospective Study for Advanced Oxidation Processes

“…The additional implementation of UV light, catalysts, hydrogen peroxide, or their combinations have been employed. [35,81,82] This approach has proved to increase the degree of mineralization of organic matter. However, more research is required to study the increased number of interactions and the possibility of radical scavenging between processes.…”

“…In recent years, the ozonation indirect pathway has been exploited to increase the oxidative potential of ozone processes by intensification with other AOPs. The additional implementation of UV light, catalysts, hydrogen peroxide, or their combinations have been employed [35,81,82] . This approach has proved to increase the degree of mineralization of organic matter.…”

A review on plasmonic-based heterojunction photocatalysts for degradation of organic pollutants in wastewater

“…Due to the increase in world population and continuous industrial and agricultural development, an increasing trend in organic pollutants in water sources has been observed worldwide [ 1 , 2 ]. Organic pollutants contained in wastewater have serious effects on the environment, human health, and consequently on the economy [ 3 , 4 ]. Moreover, water is a valuable source that needs to be adequately treated, recycled, and conserved so that it can continue to be used in all aspects of life and to protect the environment from the serious effects of organic pollutants.…”

Co-adsorption and Fenton-like oxidation in the efficient removal of methylene blue by MIL-88B@UiO-66 nanoflowers

“…4,5 Therefore, developing efficient technologies to remove organic contaminants from wastewater is an urgent issue in water management. Several physical or chemical methods have been explored to treat organic wastewater: solid-phase adsorption, 6 advanced oxidation reaction, 7,8 membrane separation, 9 biodegradation, 10 photocatalysis, 11,12 coagulation-flocculation, 13 and electrochemical treatment. 14 Advanced oxidation involves high oxidation efficiency and thorough mineralization of organics.…”
