Dye pollution has become a major threat to the environment. Advanced oxidation processes (AOPs) are widely used in dye wastewater treatment, and the selection of catalyst is of great significance. In this study, a novel composite material OMS-2/hyphae was prepared through self-assembly technique. Mycelium pellets of carrier material were prepared using a waste biomass resource as the medium of Aspergillus niger . The composite material was characterized by polarized light microscopy (PLM), X-ray diffraction (XRD), Fourier-transform infrared spectrometer (FTIR), and scanning electron microscope (SEM). The results showed that the mycelium pellet was an applicable biocarrier material for successful loading of nano OMS-2 with nearly no changes of structure. To explore the catalytic properties of such material, reactive brilliant red X-3B was selected as pollutant. The degradation capacity brought by composite material was up to 80% within 35 min, which was much higher than that with the pure OMS-2 or mycelium pellet. After four cycles, the degradation efficiency of dye was maintained above 50%, and the material was remained stable. This study provided some useful information for the application of environmentally friendly biomass material in wastewater treatment.

一种易于获得的生物载体材料菌丝颗粒与 OMS-2 组装用于染料降解

染料污染已成为对环境的主要威胁。高级氧化工艺（AOPs）广泛应用于染料废水处理，催化剂的选择具有重要意义。在这项研究中，通过自组装技术制备了一种新型复合材料 OMS-2/菌丝。使用废弃生物质资源作为黑曲霉的培养基制备了载体材料的菌丝体颗粒。通过偏光显微镜（PLM）、X射线衍射（XRD）、傅里叶变换红外光谱仪（FTIR）和扫描电子显微镜（SEM）对复合材料进行了表征。结果表明，菌丝体颗粒是一种适用的生物载体材料，可成功装载纳米 OMS-2，几乎没有结构变化。为了探索这种材料的催化性能，选择活性艳红X-3B作为污染物。复合材料带来的降解能力在 35 分钟内可达 80%，远高于纯 OMS-2 或菌丝体颗粒。4个循环后，染料降解率保持在50%以上，材料保持稳定。该研究为环境友好的生物质材料在废水处理中的应用提供了一些有用的信息。
