摘      要：The classical Fenton oxidation process(CFOP)is a versatile and effective application that is generally applied for recalcitrant pollutant ***,excess iron sludge production largely restricts its widespread *** sludge is a hazardous solid waste,which is a complex heterogeneous mixture with Fe(OH)3,organic matter,heavy metals,microorganisms,sediment impurities,and *** studies have aimed to utilize specific Fenton sludge resources based on their iron-rich characteristics,few reports have fully reviewed the utilization of Fenton *** such,this review details current sustainable Fenton sludge reuse systems that are applied during wastewater ***,coagulant preparation,the reuse of Fenton sludge as an iron source in the Fenton process and as a synthetic heterogeneous catalyst/adsorbent,as well as the application of the Fenton sludge reuse system as a heterogeneous catalyst for resource *** is the first review article to comprehensively summarize the utilization of Fenton *** addition,this review suggests future research ideas to enhance the cost-effectiveness,environmental sustainability,and large-scale feasibility of Fenton sludge applications.
