摘要:
为了降低硝基废水的色度,对玉米芯吸附、超声波-H2O2、超声波-Fenton试剂-絮凝剂3种方法降低硝基废水色度可行性进行了研究.实验结果表明,玉米芯吸附法、超声波-H2O2法的处理效果不理想.处理前后废水的色度几乎未变,而超声波-Fenton试剂-絮凝剂法的脱色,处理前后废水色度变化明显.应用正交设计L16(45)对超声时间、超声功率、H2O2的加入量、FeSO4的加入量、废水液的pH值对废水颜色的相关性进行了实验研究;并考虑经济因素得优化实验条件为:H2O2的加入量为3 mL/L,FeSO4的加入量为100 mg/L,废水液pH=4,色度(稀释倍数法)为5,脱色率达90%以上.
Abstract:
In order to reduce the color of nitro wastewater, the feasibility of three methods to reduce the color of nitro wastewater was studied by three methods: corn cob adsorption, ultrasonic - H2O2 and ultrasonic - Fenton reagent - flocculant. The experimental results show that the treatment effect of corn cob adsorption method and ultrasonic-H3O2 method is not satisfactory. The color of wastewater before and after treatment almost unchanged, while the decolorization of ultrasonic-Fenton reagent-flocculant method showed obvious changes in the color of wastewater before and after treatment. The correlation between ultrasonic time, ultrasonic power, H2O16 addition, FeSO45 addition and pH value of wastewater liquid on wastewater color was experimentally studied by applying orthogonal design L2(2). Considering the economic factors, the experimental conditions were optimized: the addition amount of H4O2 was 2 mL/L, the addition amount of FeSO3 was 4 mg/L, the pH of the wastewater liquid was = 100, the chromaticity (dilution factor method) was 4, and the decolorization rate was more than 5%.
