摘要
以活性艳红KD-8B溶液作为模拟印染废水,采用Fenton试剂法对其进行催化降解.考察了体系初始pH值、H2O2和FeSO4的投加量以及反应时间等因素对模拟废水的色度及COD去除率的影响,优化了反应条件.实验确定最佳反应条件为:室温下,pH=2.5,[Fe2+]=3.0 mmol/L,[H2O2]=39.2 mmol/L,反应时间40 min,30 mg/L的模拟染料废水脱色率和COD去除率分别达到96.6%和86.7%.Fenton试剂与厌氧微生物处理相结合的处理方式,可以显著提高模拟废水的色度和COD去除率,均达98%以上,尤其COD的去除率比单纯采用厌氧生物法和Fenton试剂法分别高出34.6%和13.1%.
Fenton reagent was used to treat reactive brilliant red KD- 8B solution. The initial pH, hydrogen peroxide and ferrous sulfate dosage and reaction time on the absorbance and COD removal rate of simulated wastewater were investigated, the reaction conditions were optimized. The results showed that the optimal reaction condition was： room temperature, pH=2. 5, [Fe~~] --3.0 mmol/L, [H202] =39.2 mmol/L, 40 min for the reaction, the removal rates of absorbance and COD of the simulating dye wastewater were 96.6% and 86.7%, respectively. Fenton method combined with anaerobic biodegradation was also used for treating the simulated dye wastewater. The results showed that the removal rates of absorbance and COD of the wastewater were all completely improved, more than 98%, the removal rate of COD were respectively higher 34.6% and 13.1% than that of treated only by anaerobic microbiodegradation or fenton reagent.
