摘　　要：文章基于超重力技术,融合臭氧高级氧化工艺,对一种较为典型的煤化工废水——高矿化度矿井水高效反渗透出水的处理进行研究,明确RPB反应器转速以及气相O_(3)浓度对COD去除率和RPB内液相总体积传质系数K_(x)a所产生的具体影响,进而确定反应参数。实验结果表明:单独O_(3)工艺以及O_(3)/H_(2)O_(2)工艺对于高矿化度矿井水的处理均取得了良好的效果,废水的COD去除率以及K_(x)a显著提升。单独O_(3)工艺处理过程中,RPB反应器转速控制在1 000 r/min,气相O_(3)浓度控制在60 mg/L的处理效果最为明显;O_(3)/H_(2)O_(2)工艺处理过程中,RPB反应器转速控制在1 200 r/min,气相O_(3)浓度控制在60 mg/L的处理效果最为明显。Based on the supergravity technology and advanced ozone oxidation process,this paper studies the treatment of high efficiency reverse osmosis effluent of high salinity mine water,which is a typical coal chemical wastewater.The specific effects of RPB reactor speed and gas phase O_(3) concentration on COD removal rate and total liquid mass transfer coefficient (kxa) in RPB were determined,and then the reaction parameters were determined.The experimental results show that both O_(3) process and O_3/H_2O_(2process) have achieved good results in the treatment of high salinity mine water,and the COD removal rate and kxa of wastewater have been significantly improved.In the process of single O_(3) process,the treatment effect is most obvious when the RPB reactor speed is controlled at 1 000 r/min,and the gas phase O_(3) concentration is controlled at 60 mg/L.In the process of O_3/H_2O_(2) process,the treatment effect is most obvious when the RPB reactor speed is controlled at 1 200 r/min and the gas phase O_(3) concentration is controlled at 60 mg/L.
