The purposes of this study were to investigate the behavior of brominated by-products, such as bromate ion and total organic bromide, formed during ozonation for the removal of estrogenic activity in sewage effluents and to propose operation parameters for the ozonation process. It is necessary to reduce the E(2) equivalent concentration of estrogenic activity in secondary effluent treated by 90% of the initial one. To do so, ozonation until dissolved ozone concentration increased to 0.1mg/L (which corresponds to approximately 1mg O(3)/mg DOC(0) [consumed ozone per initial DOC] of consumed ozone for the effluent in this study) is proposed as an operation parameter for ozonation without the formation of brominated by-products.
本研究的目的是调查臭氧化过程中形成的溴化副产物（如溴酸根离子和总有机溴）的行为，该过程用于去除污水中的雌激素活性，并提出臭氧化过程的运行参数。有必要将二级出水经处理后的雌激素活性的E(2)当量浓度降低至初始浓度的90%。为此，建议将臭氧化进行到溶解臭氧浓度增加到0.1mg/L（在本研究中，这相当于约1mg O(3)/mg DOC(0) [每初始DOC消耗的臭氧]的消耗臭氧量），作为不形成溴化副产物的臭氧化运行参数。
