摘要:
近年来，一些检出水平低但风险水平较高、处理难度较大的新污染物（Emerging Contaminants， ECs）在各类污水处理厂的进出水中频繁被检出。以生物脱氮为主体工艺的生物处理单元可同步去除氨氮及ECs，但ECs在其中的去除途径复杂，去除机理有待明确，ECs降解中间产物的毒性效应也应引起重视。基于此，分析了影响ECs在生物脱氮工艺中去除效率的关键因素，从生物及化学角度阐述了自养菌、异养菌及活性氮物质在ECs去除过程中的作用，系统地讨论了ECs的去除途径，同时对中间产物所产生的毒性效应进行了初步讨论，评估了不同类型生物脱氮工艺去除ECs的可行性，以期为应用脱氮工艺同步去除氨氮及ECs提供参考及理论指导。
Abstract:
In recent years, the emerging contaminants (ECs) with low level of detection and high level of risk are frequently detected in influent and effluent of wastewater treatment plants (WWTPs). ECs and ammonia nitrogen can be removed simultaneously in biological nitrogen removal process. However, the removal pathways and mechanism are complex and need further study. Also, the toxicity of intermediate products from ECs degradation should be paid more attention. In this background, the key factors of ECs removal in biological nitrogen removal process were analyzed. The role of autotrophic bacteria, heterotrophic bacteria, and nitrogenous compounds on ECs removal was clarified from the perspective of biology and chemistry. In addition, the transformation pathways of ECs and the toxicity of intermediate products were discussed. Furthermore, the feasibility of various biological nitrogen removal processes which are applied for ECs removal was evaluated to provide a reference and guidance for the simultaneous removal of ammonia nitrogen and ECs.
