摘要
系统掌握污水再生处理臭氧氧化系统的运行费用构成及其影响因素对降低运行费用具有重要意义。文章对污水再生处理臭氧氧化系统的运行费用进行了系统分析,结果表明,其运行费用主要由臭氧发生系统运行费用和臭氧尾气破坏系统运行费用构成,其中前者比重高达95%-99%,后者约为1%-5%。影响污水再生处理臭氧氧化系统运行费用的主要因素是臭氧投加量、臭氧气体浓度等工艺参数。在保证处理效果的前提下,提高臭氧利用率,减少臭氧投加量,以及提高臭氧气体浓度,是有效降低污水处理臭氧氧化系统运行费用的关键。
Running cost of an ozone-oxidation system relating to reclaim and reuse of wastewater was analyzed.The analysis indicated that operation cost of ozone generator,the major component of the system,accounted for around 95 to 99% of the system＇s running cost;while treatment of ozone tail gas just for 1-5%.On the other hand,the main factors that affect the running cost of an ozone oxidation system for reclaiming wastewater were ozone dosage and ozone gas concentration.It was concluded that with the premise of guaranteeing the quality of wastewater treatment,the measure to reduce the running cost of the ozone-oxidation system was to improve ozone utilization efficiency by means of cutting down ozone dosage and add to ozone gas concentration.
