摘　　要：通过紊流变流量清水的曝气试验,研究了HCR反应器的充氧性能,并考察了自制反应器的内径大小、射流量、温度对其性能的影响,得出了影响该反应器氧转移效率的主次因素顺序为:射流量→内筒直径→温度。同时确定出反应器运行的最佳射流量为2.5 m3/h,最佳内径为7 cm,为后续的试验提供了可靠的技术参数。Through the aeration experiment on variable turbulence flow, the aeration performance of HCR reactor was researched. The influence of the inner diameter, jet flow and temperature of self- made reactor to the performance were investigated. We got the sequence of the factors affecting the Oxygen - transfer efficiency as follow jet flow → inner diameter of the reactor → temperature. Mean- while we confirmed the optimum jet flow of the rector was 2.5 m3/h, optimum inner diameter was 7 cm, which provided reliable technical parameters to the following experiments.
