摘要
以超声波清洗机和空气泵构成超声曝气组合工艺降解采油废水中黄原胶的反应系统,单因素考察了反应时间、通气量、超声功率、黄原胶溶液初始浓度以及pH等因素对黄原胶降解效率的影响;并选取黄原胶溶液的pH、超声功率、通气量和时间进行了正交试验。结果表明,各种因素对黄原胶降解的影响先后为:初始pH、通气量、时间、超声功率;在pH为2、曝气量为870L·h-1、超声功率为300W以及时间75min时,废水黄原胶粘度降低可达到97.28%。
Degradation reaction system was composed by a set of ultrasonic clean machine and an airpump. The effect of factors including reaction time, aeration rate, ultrasonic power, initial concentration, pH were investigated by single-factor method. The optimal conditions for the degradation efficiency of xanthan gum and remarkable sequence of these factors were optimized by orthogonal experiment.The viscosity reduction rate of xanthan gum in aqueous solution reach up to 97%in the optimal conditions with pH of 2, aeration capacity of 870 L·h-1, ultrasonic power of 300 W and treatment time 75 min. The remarkable sequence of these factors is： initial pH, aeration, time, ultrasonic power. When the pH, the airflow, ultrasonic powerand time were 2, 870 L·h-1, 300 W, 75 min repectively, the decrease rate of xanthan viscosity can reach 97%.
