采用Fenton氧化进行污泥溶胞减量,以溶解性化学需氧量(SCOD)和剩余污泥质量浓度(TSS)作为评价指标,考察了H2O2投加量、Fe2+投加量、pH值、反应温度、反应时间对剩余污泥有机物溶出及剩余污泥减量的影响。结果表明:Fenton氧化破解剩余污泥的最佳条件为pH值3,H2O2投加量50 mL/L,Fe2+投加量0.8 g/L,反应温度50 ℃,反应时间90 min;在此优化条件下,SCOD、水质总氮、水质总磷依次由初始的49,8,0.21 mg/L增加至972,98,4.58 mg/L,污泥粒径(D 50)由初始的28.45 μm降低至14.61 μm,TSS减量率达到37.83%。
- Abstract:

The effects of H2O2 dosage, Fe2+ dosage, pH value, reaction temperature and time on organic matter dissolution and sludge decrement of excess sludge were researched by utilizing Fenton oxidation to reduce sludge lysis with dissolved chemical oxygen demand (SCOD) and sludge mass concentration (TSS) as evaluation indicators. The results showed that the optimal conditions for cracking excess sludge by Fenton oxidation were pH value 3, H2O2 dosage 50 mL/L, Fe2+ dosage 0.8 g/L, reaction temperature 50 ℃, reaction time 90 min. Under the optimal conditions, the SCOD, total nitrogen (TN) and total phosphorus(TP) had increased from the initial 49, 8, 0.21 mg/L to 972, 98, 4.58 mg/L respectively; the sludge particle size(D 50) had decreased from the initial 28.45 μm to 14.61 μm, and the sludge reduction rate of TSS had reached 37.83%.
