摘要:
随着反渗透工艺在高品质再生水生产中的广泛应用，反渗透浓水产量与日俱增。该类反渗透浓水含有大量难降解、生态毒性强的高风险有机污染物，亟须寻求绿色、高效的处理技术。系统总结和分析了市政反渗透浓水中高风险有机污染物的特征及现有技术的处理效果。目前，市政反渗透浓水中高风险有机污染物主要包括上游污水厂二级出水富集的难降解污染物、二级出水消毒产生的副产物及系统运行过程中投加的药剂。针对此类高风险有机污染物的控制，现有的常规处理方法（如物理、生物法）去除效果较差，高级氧化法对大部分有机污染物去除效果较佳，但存在产生较多的有毒中间产物、对卤代高风险有机污染物去除效果欠佳的不足；还原法可实现对卤代高风险有机物的高效脱卤，抑制其生态毒性。根据市政反渗透浓水水质的特征，提出了还原-氧化组合技术用于高风险有机污染物的控制与脱毒，以期为反渗透浓水的风险控制提供参考。
Abstract:
With the increasing application of reverse osmosis processes for producing high-quality reclaimed water, the volume of reverse osmosis concentrate (ROC) is growing. The ROC contains a large number of high-risk organic pollutants that are difficult to degrade and have significant ecological toxicity. Therefore, there is an urgent need to develop green and efficient treatment technologies for ROC. This study systematically reviews and analyzes the characteristics of high-risk organic pollutants in ROC from municipal sewage reclamation treatment and evaluates the effectiveness of existing treatment technologies. These pollutants can be categorized into three main groups: refractory pollutants enriched in the secondary effluent of wastewater treatment plants， disinfection byproducts generated during secondary effluent disinfection， and organic agents added during system operation. Conventional treatment methods (e.g., physical and biological processes) have limited removal efficiencies for these high-risk organic pollutants. Advanced oxidation processes can efficiently remove most organic pollutants but often produce toxic intermediate products and have limited efficacy against halogenated high-risk organic pollutants. In contrast, reduction processes can efficiently dehalogenate for halogenated high-risk organics and reduce their ecotoxicity. Based on the characteristics of ROC, this study proposes a combined reduction-oxidation process for the control and detoxification of high-risk organic pollution. This integrated approach aims to provide a reference for risk management of reverse osmosis concentrate from municipal sewage reclamation treatment.
