摘　　要：为探讨水力空化效应的影响因素,采用亚甲基蓝-紫外分光光度计法测量水力空化过程中产生的羟基自由基(·OH)的数量,考察亚甲基蓝浓度、出口压力、管路流量等各因素对水力空化效应的影响。结果表明:亚甲基蓝分光光度计法能够成功地捕捉到水力空化产生的羟基自由基;当出口压力为0.10 MPa、液体温度为30℃、pH值为中性、管路流量Q=800 L/h及掺入气体量为0.15 L/h时,出现最大羟基自由基浓度,此时水力空化效果最好。In order to investigate the effect of influencing factors on hydraulic cavitation,the method of methylene blue ultraviolet spectrophotometer was used to measure the number of hydroxyl radical(·OH)produced in the process of hydraulic cavitation,investigating the effect of methylene blue concentration,outlet pressure,pipeline flow rate and other factors on the hydraulic cavitation.The results show that the methylene blue spectrophotometer can successfully capture the hydroxyl radicals produced in the process of hydrodynamic cavitation,and the best hydrodynamic cavitation to produced hydroxyl radical was obtained from neutral water at 30℃ when liquid flow rate in 800 L/h along with gas in 0.15 L/h and 0.10 MPa at outlet pressure.
