摘　　要：系统掌握雾化曝气臭氧氧化系统造价及其影响因素,对降低其建设成本具有重要意义。雾化曝气臭氧氧化系统与微孔曝气臭氧氧化系统的工程造价对比结果对选择适宜的臭氧氧化工艺具有很好的指导意义。系统分析臭氧投加量、臭氧气体浓度、气液比、循环泵过流水量及处理规模等工艺参数对雾化曝气臭氧氧化系统设备造价的影响规律。结果表明,臭氧投加量和臭氧气体浓度是主要的影响因素,在保证处理效果的前提下,减少臭氧投加量、提高臭氧气体浓度及加大气液比,是有效降低雾化曝气臭氧氧化系统工程造价的关键。在其它条件相同的情况下,雾化曝气臭氧氧化系统的臭氧投加量需低于微孔曝气臭氧氧化系统的臭氧投加量30%～40%以上,其工程造价才有优势。It is very significant to lessen construction cost by systematically grasping cost of nebulization aeration ozone oxidation process and its impact factors. The contrast result of cost between nebulization aeration ozone oxidation process and micropore aeration ozone oxidation process is beneficial to optimize the ozone oxidation process. Some technological parameters as ozone dosage, ozone gas concentration, gas liquid ratio, recycle pump flow and influent flow etc. which have an effect upon construction cost and its law are systematically analyzed. It is conclude that the mote important factors are the ozone dosage and ozone gas concentration. On the premise of improving the treatment effect, the key measures to decrease the construction costs of ozonation system is improving ozone utilization rate by reducing ozone dosage, increasing ozone gas concentration and adding gas liquid ratio. Under the same other parameter, the construction cost of nebulization aeration ozone oxidation system would have an advantage over micropore aeration if the ozone dosage of nebulization aeration is lower as over 30%-40% than micropore aeration.
