Abstract

Water pollution by recalcitrant organic contaminants is a recognized issue of significant concern since a wide range of these contaminants has been found in environmental matrices resulting in severe environmental and health issues. The role of wastewater treatment technologies is becoming more critical with the growing presence of these recalcitrant organic compounds in water. The removal of these compounds from environmental matrices has proved a difficult challenge for the scientific and technical community, as no single process is available for their degradation and mineralization. Advanced oxidation processes (AOPs) possess a great ability to treat a wide variety of these pollutants and to improve the biodegradability of wastewater. Still, they have some important drawbacks like high operational costs resulting from the consumption of energy and chemicals. In this framework, technological advancement, including the integration of AOPs with biological treatment, may help in reducing the pollutant concentration to the desired level, ensuring the better quality of water. This review addresses the combination of AOPs and biological processes used for the degradation of organic pollutants present in waters and wastewaters. Recent works on the combination of AOP and biological processes are summarized and discussed, including scientific, technical and economic aspects. Finally, conclusions and future perspectives for this line of research are presented.

摘要

顽固性有机污染物对水的污染是公认的重大问题，因为在环境基质中发现了广泛的这些污染物，从而导致严重的环境和健康问题。随着这些难处理的有机化合物在水中的出现，废水处理技术的作用变得越来越重要。从环境基质中去除这些化合物已被证明对科学和技术界来说是一个艰巨的挑战，因为没有单一的方法可用于降解和矿化。先进的氧化工艺（AOP）具有强大的能力来处理各种污染物，并提高废水的生物降解性。仍然，它们具有一些重要的缺点，例如由于消耗能源和化学药品而导致运营成本高昂。在这种框架下，技术进步，包括将AOP与生物处理相结合，可能有助于将污染物浓度降低到所需水平，从而确保更好的水质。这项审查解决了AOPs和用于降解水和废水中有机污染物的生物过程的结合。总结和讨论了有关AOP和生物过程结合的最新工作，包括科学，技术和经济方面。最后，提出了这一研究领域的结论和未来展望。可能有助于将污染物浓度降低到所需水平，从而确保更好的水质。这项审查解决了AOPs和用于降解水和废水中有机污染物的生物过程的结合。总结和讨论了有关AOP和生物过程结合的最新工作，包括科学，技术和经济方面。最后，提出了这一研究领域的结论和未来展望。可能有助于将污染物浓度降低到所需水平，从而确保更好的水质。这项审查解决了AOPs和用于降解水和废水中有机污染物的生物过程的结合。总结和讨论了有关AOP和生物过程结合的最新工作，包括科学，技术和经济方面。最后，提出了这一研究领域的结论和未来展望。技术和经济方面。最后，提出了这一研究领域的结论和未来展望。技术和经济方面。最后，提出了这一研究领域的结论和未来展望。
