摘要
以城市污水处理厂的浓缩池污泥作为研究对象,研究了基于Fenton高级氧化技术-骨架构建体组合对污泥脱水性能的影响。结果表明,Fenton高级氧化和骨架构建体组合能够显著改善污泥的脱水性能,当pH约为5,Fe^(2+)投加量为45 mg/g,H_2O_2投加量为315 mg/g,生石灰和粉煤灰投加量均为500 mg/g时,复合调理污泥的脱水性能最佳,脱水污泥含水率为51.52%。
The effects of Fenton advanced oxidation technology combining with skeleton builders on the dewaterability of sewage sludge from concentrated tank in the sewage treatment plant were investigated. The experimental results show that Fenton advanced oxidation technology and skeleton builders can improve the dewaterability of sludge. The water content of dewatered sludge can be reduced to 51.52% with the Fe^（2＋） dosage of 45mg/g, H_2O_2 dosage of 315 mg/g, lime dosage of 500 mg/g, fly ash dosage of 500 mg/g, at a pH of about 5.
