摘要 在序批式污泥厌氧反应器中探究了高铁酸钾对污泥破解及厌氧产酸的影响。实验结果表明高铁酸钾对污泥具有较强的破解性,当高铁酸钾的质量浓度由0 mg/L增加至16 mg/L时,溶解性COD与总COD的比值由6.2%升至35.6%。同时污泥液相中溶解性蛋白质的质量浓度由561 mg/L增加至1 365 mg/L。高铁酸钾的浓度与挥发性悬浮固体(VSS)的减量具有一定的线性关系。当高铁酸钾的质量浓度为8 mg/L时,污泥厌氧产挥发性脂肪酸最大,并且最大值为895 mg/L,其浓度是空白组2.56倍。 The effects of potassium ferrate on the sludge disruption and anaerobic production of volatile fatty acids in sequential batch sludge anaerobic reactor were investigated. The results showed that potassium ferrate had strong crack ability to sludge,and when the concentration of potassium ferrate increased from 0 mg/L to 16 mg/L,the ratio of soluble COD and total COD increased from 6. 2% to 35. 6%. Meanwhile the concentration of soluble protein in the sludge liquid phase increased from 561 mg/L to 1 365 mg/L. The concentration of potassium ferrate had a linear relationship with the decrease of volatile suspended solids. When the concentration of potassium ferrate was 8 mg/L,the sludge anaerobic production of volatile fatty acids reached its highest,maximum to 895 mg/L,and its concentration was 2. 56 times of that in the blank one.
