Abstract

Increasing input of endocrine disrupting chemicals (EDCs) has been increasing rapidly nowadays. Various wastewater treatment technologies have been studied to remove EDCs in water and wastewater. Due to its high oxidation potential and other benefits over other tertiary wastewater treatments, the establishment of advanced oxidation processes based on sulfate radicals (SR-AOP) has been of attention in recent years. There are numerous activation methods to produce sulfate radicals from peroxymonosulfate (PMS) and peroxydisulfate (PDS) such as ultrasound, transition metals, and the use of carbon catalysts. This review manuscript focuses to provide the latest overview of different methods of PDS and PMS activation and different utilization of this technology focusing on water and wastewater treatment. Besides that, this article also focused on the utilization of carbon-based catalysts as a substitute for metal catalysts as an activator in the SR-AOP process. This review also aims to discuss the perspectives for the biochar-based catalyst application and expand their potential for removing organic pollutants.

生物炭基硫酸盐自由基深度氧化工艺及其在废水中内分泌干扰物降解中的应用综述

近年来，内分泌干扰物(EDCs)的投入急剧增加。人们研究了各种废水处理技术来去除水和废水中的EDCs。基于硫酸根自由基的高级氧化工艺(SR-AOP)由于具有较高的氧化电位和优于其他三级废水处理的优点，近年来受到了人们的关注。从过氧单硫酸盐(PMS)和过氧二硫酸盐(PDS)中产生硫酸盐自由基的活化方法有很多，如超声波、过渡金属和碳催化剂的使用。本文主要介绍了PDS和PMS的不同活化方法及其在水和废水处理中的不同应用。此外，本文还重点介绍了碳基催化剂在SR-AOP过程中替代金属催化剂作为活化剂的应用。本文还讨论了生物炭基催化剂的应用前景，并进一步拓展了其去除有机污染物的潜力。
