摘要
近年来,活化过碳酸盐高级氧化技术具有低成本、安全、稳定等特点,已广泛用于处理水中的各类有机污染物,有望成为一种新兴的环境友好型水处理技术。该文介绍了活化过碳酸盐降解有机污染物的机理;系统综述了均相活化、非均相活化、物理活化、其他活化过碳酸盐的活化方法与活化反应机理;总结了过碳酸盐高级氧化法在水处理中的应用,重点阐述了过碳酸盐高级氧化法在去除水中的有机污染物、膜污染控制、污泥脱水、污泥厌氧消化等方面的应用研究现状;最后,指出目前水处理研究领域活化过碳酸盐高级氧化技术存在的问题,并对未来的重点研究方向进行了展望。
In recent years,the advanced oxidation process of activated percarbonate has been applied in the treatment of various organic pollutants in water due to its low cost,safety and stability,and is expected to become a new environment-friendly water treatment technology.Herein,the oxidative degradation mechanism of organic pollutants by activated percarbonate was introduced,followed by systematical review on the different activation methods and reaction mechanisms of percarbonate such as homogeneous activation,heterogeneous activation,physical activation,other activation methods.The application of advanced oxidation process of activated percarbonate in water treatment was then summarized with the emphasis on the research status in removal of organic pollutants in wastewater,membrane pollution control,sludge dewatering,sludge anaerobic digestion and so on.In the end,the existing problems and the future development direction were discussed.
