In this study, simultaneous pre and post-ozonation processes combined biological attached growth reactor were used in order to investigate the removal of COD, ammonium and total coliforms from real municipal wastewater. The biological process was carried out in a fixed bed aerobic bioreactor with an aeration rate of 6 L/min and hydraulic retention time of 5 h. The ozonation process was performed simultaneously in pre-ozonation and post-ozonation reactors, with 1 g/h ozone mass flow within 30 min every 8 h. The results showed that complete ammonium removal and 94 % COD removal were obtained. Also, total coliforms in the final effluent were measured to be about 0.51 MPN/mL. The analysis of energy consumption showed that the ozonation process was the dominant energy consumption source. The combination of fixed bed bioreactor and ozonation process showed a promising technology for the treatment of real municipal wastewater.

在这项研究中，同时进行的臭氧处理前和后臭氧处理工艺与生物附着生长反应器相结合，用于研究从实际市政废水中去除COD，铵和总大肠菌群的方法。生物过程在固定床好氧生物反应器中进行，曝气速率为6 L / min，水力停留时间为5 h。臭氧化过程在臭氧前和臭氧后反应器中同时进行，每8小时30分钟内臭氧质量流量为1 g / h。结果表明获得了完全的铵去除和94％的COD去除。同样，最终流出物中的大肠菌群总含量约为0.51 MPN / mL。能耗分析表明，臭氧化过程是主要的能耗来源。
