Abstract

The contamination of water resources has become a significant challenge that threatens the health and well-being of people’s daily life; it calls for new technologies to be applied for water purification. Heterogeneous Fenton or Fenton-like techniques have a lot of potential as a new approach for treating wastewater because of the advantages in efficiency, safety, and economics. Various advanced oxidation processes (AOPs) are comprehensively reviewed in this work, and the •OH generation methods including chemical, electro-chemical, and photochemical approaches are summarized. Some key parameters that influence the reaction efficiency such as the temperature, catalysts, H2O2 dosage, and pH are investigated. The reaction mechanism and process optimization of photocatalysis are specifically highlighted.

水净化应用的高级氧化工艺
水资源污染已成为威胁人们日常生活健康和福祉的重大挑战;它要求将新技术应用于水净化。非均相Fenton或类Fenton技术具有高效、安全、经济等优点,是一种极具潜力的污水处理新方法。本文对各种高级氧化工艺(AOPs)进行了综述,总结了•OH的生成方法,包括化学方法、电化学方法和光化学方法。考察了温度、催化剂、H2O2用量、pH等影响反应效率的关键参数。重点介绍了光催化的反应机理和工艺优化。
