摘　　要：芬顿氧化反应具有氧化多种有毒有害的有机物、使用范围广等特点,采用芬顿氧化技术深度处理重庆市某餐厨垃圾处理厂厌氧消化废水,研究不同pH值、双氧水及七水硫酸亚铁的投加量等因素对餐厨垃圾厌氧消化废水深度处理效果的影响。实验结果表明最佳反应条件为:废水初始pH值为3.5、双氧水投加量为0.8 mL/L、七水硫酸亚铁投加量为4 mL/L,在此条件下反应90 min,废水CODCr去除率可达到53.29%。Fenton oxidation reaction has the characteristics of oxidizing a variety of toxic and harmful organic substances, and has a wide range of uses. Fenton oxidation technology was used to deeply treat an anaerobic digestion wastewater from a kitchen waste treatment plant in Chongqing, and different pH values, hydrogen peroxide, and sulfuric acid heptahydrate effect of factors such as the amount of iron added on the advanced treatment effect of anaerobic digestion wastewater of kitchen waste were studied. The experimental results showed that the optimal reaction conditions were as follows: the initial pH of the wastewater was 3.5, the dosage of hydrogen peroxide was 0.8 mL/L, and the dosage of ferrous sulfate heptahydrate was 4 mL/L. Under these conditions, the reaction was performed for 90 min, and CODCr removal rate of the wastewater can reach 53.29%.
