摘要

以来自市政污水处理厂和炼化污水处理厂的两种剩余污泥为研究对象，对比分析了其在600 ℃下制备的热解炭的性质、活化过氧乙酸(PAA)的性能及反应路径。结果表明，两种热解炭均具有粗糙的表面形貌和丰富的元素种类，相较于市政剩余污泥热解炭(MS)，炼厂剩余污泥热解炭(RS)具有更高的比表面积(123.5 m

/g)和sp

杂化碳含量(32.8%)，以及更大的孔体积(0.26 cm

/g)。MS对双酚A(BPA)几乎没有吸附作用，其活化PAA降解BPA的反应速率常数(k

；RS则可吸附去除33.6%的BPA，其活化PAA降解BPA的k

，且共存阴离子不抑制BPA降解。RS通过电子转移过程(ETP)活化PAA降解BPA，其中sp

杂化结构形成的离域π电子是介导ETP的主要活性位点；MS则通过表面Fe(II)活化PAA生成的Fe(IV)=O降解BPA，仅伴随微弱的ETP过程。产物分

析显示，BPA在两体系中均于溶液和热解炭表面同步发生降解：热解炭表面主要通过聚合反应产生二聚体和三聚体；在溶液反应中，MS/PAA体系中BPA通过断键与开环反应生成小分子酸，而RS/PAA体系中BPA发生断键与乙酸加成反应，生成分子量更大的酯类化合物。本研究为炼厂剩余污泥热解炭在有机污染物治理中的应用提供了理论依据。

Abstract

Using two types of excess sludge derived from a municipal wastewater treatment plant and a petrochemical wastewater treatment plant as raw materials

this study comparatively investigated the properties of pyrolytic char prepared at 600℃

as well as their performance and reaction pathways in activating peracetic acid (PAA). The results demonstrated that both pyrolytic char exhibited rough surface morphologies and diverse elemental compositions. Compared with municipal sludge-derived pyrolytic char (MS)

refinery sludge-derived pyrolytic char (RS) possessed a higher specific surface area (123.5 m

/g)

greater sp

-hybridized carbon content (32.8%)

and larger pore volume (0.26 cm

/g). MS showed negligible adsorption capacity toward bisphenol A (BPA)

with a reaction rate constant(k

) of only 0.025 min

for BPA degradation via PAA activation. In contrast

RS achieved 33.6% BPA removal through adsorption alone

and exhibited a significantly higher k

obs

of 0.729 min

for PAA-activated degradation. Moreover

the coexisting anions do not inhibit the degradation of BPA in the RS/PAA system. Mechanistically

RS activated PAA predominantly through an electron transfer process (ETP)

in which delocalized π electrons associated with sp

-hybridized carbon structures served as the primary active sites. In comparison

MS activated PAA mainly via surface Fe(II)

generating Fe(IV)=O species responsible for BPA degradation

accompanied by only a minor contribution from ETP. Product analysis revealed that BPA degradation occurred simultaneously in both the aqueous phase and on the surface of the pyrolytic char in both systems. On the pyrolytic char surface

polymerization reactions led to the formation of dimers

and trimers. In the aqueous phase

BPA in the MS/PAA system underwent bond cleavage and ring-opening reactions to form small molecular acids

whereas in the RS/PAA system

BPA experienced bond cleavage followed by acetic acid addition

producing ester compounds with higher molecular weights. This study provides a theoretical basis for the application of refinery sludge-derived pyrolytic char in the treatment of organic pollutants.
