Abstract

Abstract:

The effects of potassium ferrate on the degradation of organic matter in wastewater pretreatment process were studied. The effects of potassium ferrate dosage, reaction time and pH on the degradation of organic matter were investigated. The effects of potassium ferrate on the degradation of organic matter were analyzed by means of fluorescence analysis. The results showed the increase of potassium ferrate dosage was more helpful to the degradation of organic matter under acidic conditions, and the degradation of COD did not change significantly when the dosage increased to 50 mg/L. It showed that potassium ferrate had good removal effect on tyrosine-like and fulvic acid-like in water by fluorescence analysis.

Key words: potassium ferrate, different carbon source organic matter, wastewater treatment

摘要：

研究了高铁酸钾在污水预处理过程中对有机物的降解特性，考察了高铁酸钾投加量、反应时间和pH等因素对有机物降解效果的影响，采用荧光分析的手段，分析了高铁酸钾对水中不同类有机物的降解效果。研究表明，在酸性条件下，高铁酸钾投加量的增加更有助于有机物的降解，投加质量浓度增加到50 mg/L后，COD的降解不再有显著的变化。荧光分析表明，高铁酸钾对水中类酪氨酸、类富里酸类有机物均有较好的去除效果。
