The world faces tremendous challenges and environmental crises due to the rising strength of wastewater. The conventional technologies fail to achieve the quality water that can be reused after treatment means "zero effluent" discharge of the industrial effluent. Therefore, now the key challenge is to develop improved technologies which will have no contribution to secondary pollution and at the same time more efficient for the socio-economic growth of the environment. Sustainable technologies are needed for wastewater treatment, reducing footprint by recycling, reusing, and recovering resources. Advanced oxidation process (AOP) is one of the sustainable emerging technologies for treating refractory organic contaminants present in different industrial wastewaters like textile, paper and pulp, pharmaceuticals, petrochemicals, and refineries. This critical review emerges details of advanced oxidation processes (AOPs), mentioning all possible permutations and combinations of components like ozone, UV, the catalyst used in the process. Non-conventional AOP systems, microwave, ultrasound, and plasma pulse assisted are the future of the oxidation process. This review aims to enlighten the role of AOPs for the mineralization of refractory organic contaminants (ROC) to readily biodegradable organics that cannot be either possible by conventional treatment. The integrated AOPs can improve the biodegradability of recalcitrant organic compounds and reduce the toxicity of wastewater, making them suitable for further biological treatment.
由于废水强度不断增加，世界面临着巨大挑战和环境危机。传统技术无法实现经处理后可再利用的优质水，即工业废水的“零排放”。因此，目前的关键挑战是开发改进技术，这些技术不会造成二次污染，同时对环境的社会经济增长更高效。废水处理需要可持续技术，通过回收、再利用和资源回收来减少碳足迹。高级氧化工艺（AOP）是用于处理纺织、造纸和制浆、制药、石化和炼油等不同工业废水中存在的难降解有机污染物的可持续新兴技术之一。这篇批判性综述阐述了高级氧化工艺（AOPs）的细节，提及了该工艺中使用的臭氧、紫外线、催化剂等所有可能的组件排列组合。非常规AOP系统，如微波、超声和等离子体脉冲辅助，是氧化工艺的未来发展方向。本综述旨在阐明AOPs在将难降解有机污染物（ROC）矿化为常规处理无法实现的易生物降解有机物方面的作用。集成AOPs可以提高难降解有机化合物的生物降解性，降低废水毒性，使其适合进一步的生物处理。
