污泥脱水性能提高是污泥减量化的关键途径。本文通过查阅国内外相关文献,介绍了Fenton、类Fenton处理污泥的研究概况。从文献报道情况看,就Fenton、类Fenton反应改善污泥脱水性能、提高污泥稳定性及改善污泥沉降性能方面的研究较多。研究结果表明,Fenton、类Fenton反应在改善污泥脱水性能、提高污泥稳定性及改善污泥沉降性能方面均有良好的作用。但Fenton氧化处理改善污泥脱水性能的作用机制尚不清楚,还有待进一步加强研究。
Improvement of the ability of sludge dewater is a key way to reduce sewage sludge. Trough reviewing relevant litera- tures, research overview of sludge treatment by Fentong reagent is described. A number of researches are made on improving sludge" dewatering, stabilization and settle ability by Fentong reagent. And results show that Fenton reaction has a good effect on those aspects. However, mechanism of Fenton'effect on improving sludge dewater ability is unclear. More researches in this field are needed.
