Bomaplex Red CR-L textile dye was used in the experimental studies. Taguchi method was applied to determine optimum conditions in the removal of dye from synthetic textile wastewater. After the parameters were determined to remove Bomaplex Red CR-L dye from synthetic textile wastewater, the experimental studies were realized. The chosen experimental parameters and their ranges: HCO3- (mM), 0-39; temperature (degrees C), 18-70; ozone-air flow rate (l min-1), 5-15; the dye concentration (ppm), 200-600; particulate activated carbon (PAC) (g), 0-1.5; H2O2 (mM), 0-0056; pH, 3-12; and treatment time (min), 10-30, respectively. An orthogonal array L18 (2(1)x3(7)) for experimental plan and the smaller the better performance statistics formula were selected to define optimum conditions. The optimum conditions were found to be as follows: HCO3- (mM), 0; temperature (degrees C), 70; ozone-air flow rate (l min-1), 10; the dye concentration (ppm), 200; particulate activated carbon (PAC) (g), 1; H2O2 (mM), 0.056; pH, 12; and time (min), 20. Under these optimum conditions, it was determined that the Bomaplex Red CR-L removal efficiency from textile wastewater was 99%.
实验研究中使用了Bomaplex Red CR-L纺织染料。采用田口方法确定从合成纺织废水中去除染料的最佳条件。在确定了从合成纺织废水中去除Bomaplex Red CR-L染料的参数后，开展了实验研究。选定的实验参数及其范围分别为：HCO3-（毫摩尔），0 - 39；温度（摄氏度），18 - 70；臭氧-空气流速（升/分钟），5 - 15；染料浓度（ppm），200 - 600；颗粒活性炭（PAC）（克），0 - 1.5；H2O2（毫摩尔），0 - 0.056；pH值，3 - 12；处理时间（分钟），10 - 30。选择实验计划的正交阵列L18(2(1)x3(7))和越小越好的性能统计公式来确定最佳条件。发现最佳条件如下：HCO3-（毫摩尔），0；温度（摄氏度），70；臭氧-空气流速（升/分钟），10；染料浓度（ppm），200；颗粒活性炭（PAC）（克），1；H2O2（毫摩尔），0.056；pH值，12；时间（分钟），20。在这些最佳条件下，确定纺织废水中Bomaplex Red CR-L的去除效率为99%。
