Ozonation followed by a polishing moving bed biofilm reactor (MBBR) was implemented in pilot and laboratory to remove the residual pharmaceuticals and toxicity from wastewater effluent, which was from a pilot hybrid system of MBBR and activated sludge, receiving municipal wastewater. The delivered ozone dosages achieving 90% pharmaceutical removal were determined both in pilot and laboratory experiments and they were normalised to dissolved organic carbon (DOC), illustrating our findings were comparable with previously published literature. During wastewater ozonation, the intensity of natural fluorescence was found to be greatly associated with the concentrations of the studied pharmaceuticals. In pilot experiments, toxicity, measured by Vibrio fischeri, increased after ozonation at delivered ozone dosages at 0.38–0.47 mg O3/mg DOC and was completely removed by the subsequent polishing MBBR. Laboratory experiments verified that the polishing MBBR was able to remove the toxicity produced by the ozonation.

与后续抛光生物膜反应器相比，通过臭氧处理去除生物预处理城市废水中的药物、毒性和天然荧光

在中试和实验室中实施臭氧化和抛光移动床生物膜反应器 (MBBR)，以去除废水中的残留药物和毒性，废水来自 MBBR 和活性污泥的中试混合系统，接收城市废水。在中试和实验室实验中确定了实现 90% 药物去除率的交付臭氧剂量，并将它们归一化为溶解有机碳 (DOC)，说明我们的发现与以前发表的文献相当。在废水臭氧化过程中，发现自然荧光的强度与所研究药物的浓度密切相关。在试点实验中，由费氏弧菌测量的毒性在臭氧处理后以 0.38-0 的臭氧剂量增加。47 mg O3/mg DOC 并被随后的抛光 MBBR 完全去除。实验室实验证实，抛光MBBR能够去除臭氧化产生的毒性。
