摘要

摘要: 基于污泥生物炭的高级氧化技术，将城市污水处理、制药、制革、印染、石油工业等多行业产生的废弃污泥再利用，不仅能够减少污泥堆积造成的环境问题，还能有效缓解水污染，具有深远的环境、社会效益。为系统了解污泥生物炭在高级氧化过程中的研究进展，详细阐述了未改性污泥生物炭和改性污泥生物炭在过硫酸盐、过氧化氢、过氧乙酸以及高碘酸盐等不同氧化体系中的内在联系、反应机制和主要强化作用。污泥生物炭一般通过元素改性、酸碱处理等方法进行改性。不同的污泥生物炭内部含有多种元素和含氧官能团，具有优异的比表面积和孔隙结构，独特的性质促使其在高级氧化体系中可产生强氧化自由基、单线态氧等活性物质，进而实现抗生素、染料以及其他有毒有害污染物的高效降解。该文可为未来污泥生物炭的开发与应用提供了新的思路和理论支撑。

Abstract: Advanced oxidation technology based on sludge biochar reuses waste sludge generated by various industries， including municipal sewage treatment plants， pharmaceutical factories， tanneries， dyeing and printing factories， and petroleum industrial plants，etc. It can not only reduce environmental problems caused by sludge accumulation but also effectively alleviate water pollution， yielding far-reaching environmental and social benefits. In order to systematically and comprehensively understand the research progress of sludge biochar in advanced oxidation processes， this paper focused on summarizing the intrinsic connections， reaction mechanisms， and main reinforcing effects of unmodified sludge biochar and modified sludge biochar in different advanced oxidation systems such as persulfate， hydrogen peroxide， peracetic acid， and periodate. The modification methods of sludge biochar generally include the modification of metal and non-metal elements， acid-base treatment. sludge biochar contains various elements and oxygen-containing functional groups. Sludge biochar has excellent surface area and pore structure. The unique properties of sludge biological carbon enable it to efficiently produce active substances， such as strong oxidizing free radicals and singlet oxygen in advanced oxidation systems such as persulfate， hydrogen peroxide， peracetic acid， and periodate， thus achieving efficient degradation of antibiotics， dyes， and other toxic and harmful pollutants. This paper provides new ideas and theoretical support for the future development and application of sludge biochar.
