Fenton技术处理市政污泥综述

国内外学者对Fenton技术处理市政污泥的研究均表明其能显著改善污泥脱水性能。这主要是因为Fenton试剂能产生氧化能力超强的OH·,其可以快速将污泥中微生物的胞外聚合物(EPS)氧化分解,降低污泥的有机质,从而提高污泥脱水性能。文章尝试通过阐述目前Fenton技术对市政污泥的作用机理、处理效果、对后续处置影响分析、经济性能分析和工程应用情况,以评估这种技术对市政污泥的工程应用前景。

A Review of the Treatment of Municipal Sludge by Fenton Technology

Domestic and foreign scholars＂ study of the treatment of municipal sludge by Fenton technology all show that it can significantly improve its dewaterability. This is mainly because Fenton reagent can produce OH- which has strong oxidation ability; it can quickly oxidize the extracellular polymers （EPS） in the sludge microorganisms and reduce the organic material of sludge, which can improve the its dewaterability. The paper tried to state the mechanism of the municipal sludge by Fenton technology, treatment effect, analysis of subsequent disposal, analysis of its economic performance and its current engineering application, in order to evaluate the application prospect of municipal sludge by Fenton technology.
