Abstract:

三元复合驱采油开发中注入的聚丙烯酰胺等化学物质随采出液一并采出,导致采出液黏度增加,受此影响,污水处理系统沉降过滤装置处理效率下降,出水水质难以稳定达标回注。降低黏度关键在于降解污水中聚丙烯酰胺,本研究采用O3氧化降解聚丙烯酰胺,降解过程中引入超声,利用超声强化作用提高O3降解效率。结果表明,在三频正交场(20kHz+28kHz+40kHz)作用下,控制声强1.6W·cm-2,作用时间15min,进水聚丙烯酰胺平均含量300mg·L-1,黏度4.5mPa·s,降解聚丙烯酰胺后水体黏度降低到0.7mPa·s,黏度变化率达到86.1%。通过检测反应前后水中和大气中O3浓度,表明超声强化作用将O3利用率提高55%。O3降解过程引入超声产生协同效应,增加了O3传质效率,促进O3转化为H2O2,进而生成高活性·OH,促使聚丙烯酰胺降解效率提高3倍,反应时间约缩短3/4。
