The major pathway of pharmaceuticals from urban applications to urban surface waters is via wastewater treatment plants. Ozonation is able to remove pharmaceuticals from wastewater effluents. However, during that reaction ozonation products are formed. Some ozonation products were found to be persistent and have adverse effect on the environment. Moving bed bio reactors (MBBRs) were tested for the removal of the ozonation products of macrolide antibiotics and diclofenac at two different concentration levels 1 µg/L and 10 µg/L in laboratory reactors. It was found that the MBBRs are capable of degrading these compounds without back-transformation into the parent compounds. However, reaction rate constants and the degradation kinetics varied for different compounds and different concentrations. Depending on compound and conditions, the degradation reaction kinetics was found to follow either i) zero order ii) first order or iii) lag phase succeeded by first order. The study has proven that MBBRs have the potential to be efficient in polishing post ozonation treatment.

药物从城市应用到城市地表水的主要途径是通过废水处理厂。臭氧化能够从废水中去除药物。然而，在该反应期间，形成臭氧化产物。发现某些臭氧化产品具有持久性，并且对环境有不利影响。测试了移动床生物反应器（MBBR）在实验室反应器中两种不同浓度水平1 µg / L和10 µg / L时大环内酯类抗生素和双氯芬酸的臭氧化产物的去除率。已发现MBBR能够降解这些化合物而不会反转化为母体化合物。但是，对于不同的化合物和不同的浓度，反应速率常数和降解动力学会有所不同。根据化合物和条件，发现降解反应动力学遵循i）零阶ii）一阶或iii）滞后相继一阶。研究证明，MBBR具有在臭氧化后处理中进行抛光的潜力。
