Concentrated leachate (CL) contains typical high concentration of Cl^-, and it is necessary to remove Cl^- efficiently and even to achieve a high value-added product from the Cl^- removal process. In this study, a Bi-contained upconversion glass-ceramic (GC) is firstly explored for ultra-efficient removal and utilization of Cl^-, wherein the abundant porous structure is continuously formed in the Cl^- removal process to further provide channels for the deep migration of Cl^- and H⁺ to its inner Bi source. The high Cl^- removal rates above 96% were all achieved over the best GC sample at the Cl^- concentrations of 1300-13000 mg/L, then the terminal BiOCl-based precipitates were directly collected as the near-infrared (NIR) GC photocatalysts, which possessed defect-rich heterostructure with excellent upconversion luminescence and electronic energy transmission properties. In the degradation of norfloxacin (NOR), high removal rates of 98%, 73%, and 36% were achieved under UV-Vis-NIR, Vis-NIR, and NIR irradiations. On a basis of the four possible NOR degradation pathways discussed, we found that the primary active species were attributed to O₂^·- and ^·OH radicals under NIR and UV-Vis-NIR irradiations, respectively. Therefore, the Bi-contained GC will supply a new strategy for high-efficiency Cl^- removal and value-added resource utilization.

浓缩浸取液（CL）包含的Cl典型的高浓度^- ，并且有必要除去Cl ^-有效地，甚至实现了从氯高附加值产品^-去除处理。在这项研究中，在Bi含式上转换玻璃-陶瓷（GC）首先探讨了超高效去除和利用的Cl ^- ，其中，所述丰富多孔结构被连续地形成在氯^-去除过程，以进一步提供用于深通道的Cl迁移^-和H ⁺到其内碧源。高氯^-去除率96％以上都在在C1-最好的GC样品实现^-浓度为1300-13000 mg / L，然后直接收集基于BiOCl的末端沉淀物作为近红外（NIR）GC光催化剂，其具有富缺陷的异质结构，具有出色的上转换发光和电子能量传输性能。在诺氟沙星（NOR）的降解中，在UV-Vis-NIR，Vis-NIR和NIR照射下，去除率高达98％，73％和36％。在讨论的四种可能的NOR降解途径的基础上，我们发现主要活性物质分别归因于NIR和UV-Vis-NIR照射下的O ₂ ^·-和^· OH自由基。因此，碧包含GC将提供高效率氯的新战略^-去除和增值的资源利用率。
