    摘要:

    针对压裂返排液有机污染物降解难度大、处理工艺复杂等问题,本文采用单因素分析和正交实验研究了压裂返排液关键污染物羟丙基胍尔胶的超声降解规律,并探讨了其降解机理。结果表明:羟丙基胍尔胶超声降解机理主要以物理剪切断链为主,超声模式和超声功率为羟丙基胍尔胶降解反应的主控参数,其次是浓度,超声时间、温度、pH值等因素影响较小。对于一定浓度的羟丙基胍尔胶溶液,最优降解参数为:超声模式40%、超声功率360W、超声时间60min、温度25℃,鉴于温度和pH值影响较小,超声降解技术可以应用于较宽的温度范围(5 ℃-50 ℃)和酸碱度范围(pH 5.0-11.0)。

    Abstract:

    To solve the problem of the degradation of organic pollutants in fracturing flow-back fluid is difficult and the treatment process is complex, the author of this paper had analyzed the mechanism of ultrasonic degradation of hydroxypropyl guar gum, which is a key contaminant in fracturing flow-back fluid. The results suggest that the mechanism of ultrasonic degradation of hydroxypropyl guar gum is mainly physical shearing, ultrasonic mode and power are the main controlling parameters of hydroxypropyl guar gum degradation reaction, followed by concentration. The ultrasonic time, temperature, pH value and other factors have little influence on hydroxypropyl guar gum degradation reaction. For a certain concentration of hydroxypropyl guar gum solution, the optimal degradation parameters are as follows: ultrasonic mode 40%, ultrasonic power 360W, ultrasonic time 60min, temperature 25℃, because of temperature and pH has little influence on hydroxypropyl guar gum degradation reaction, ultrasonic degradation technology can be applied to a wide temperature range (5℃-50℃) and pH range (pH 5.0-11.0).
