染料废水和粉虫废物的大量产生已经显示出潜在的危险。本研究开发了一种新型的光助Fenton类非均相催化剂-负载铁的黄粉虫（Tenebrio molitorLinnaeus的幼虫）残渣基生物炭（Fe/FBC）。采用X射线粉末衍射、扫描电子显微镜、X射线能谱、X射线光电子能谱、傅里叶变换红外光谱、Brunsuer-Emmett-Teller、拉曼光谱、电感耦合等离子体光谱和N2吸附-脱附等温线等手段对复合材料的理化性质进行了表征。结果表明，Fe（III）成功负载在Fe/FBC表面上，负载量为6.0wt%，并且在Fe/FBC中出现高表面积（90.65 m2 g-1）的石墨化度增加。在光助非均相类Fenton体系中，Fe/FBC对孔雀石绿色（MG）染料的去除效果最好（5 min内TOC去除率达67%），并具有良好的循环利用性能，表明光的辅助作用可以加速非均相类Fenton反应，实现协同强化MG降解。基于超高效液相色谱-串联质谱的结果，提出了三种可能的MG降解途径，包括N-去甲基化、羟基化和共轭发色团的破坏。采用生命周期评价方法，对Fe/FBC催化处理（方案A）和堆肥处理（方案B）两种粪质废弃物处置策略的环境影响进行了评价。就十个影响类别而言，与情景B相比，情景A产生的环境足迹较低，表明促进Fe/FBC是缓解温室效应、能源危机、水毒性和富营养化的经济和环境可行的战略。
The massive generation of dye wastewater and mealworm waste has shown potential dangers. In this study, an innovative method was developed to fabricate an efficient photo-assisted Fenton-like heterogeneous catalyst, namely, iron (Fe)-loaded mealworms (the larvae ofTenebrio molitorLinnaeus) frass-based biochar (Fe/FBC). The physico–chemical properties were characterized by X-ray powder diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Brunsuer-Emmett-Teller, Raman spectroscopy, inductively coupled plasma spectroscopy, and N2sorption-desorption isotherms. The results revealed the successful loading of Fe(III) on Fe/FBC surface with a loaded content of 6.0 wt%, and increased graphitization degree with high surface area (90.65 m2g−1) appeared in Fe/FBC. Excellent removal efficiency toward malachite green (MG) dye (67% TOC within 5 min) and good recycling performance of Fe/FBC were observed in photo-assisted heterogeneous Fenton-like system, indicating that the aid of light irradiation may accelerate the heterogeneous Fenton-like reaction and realize the synergistic effect of enhanced MG degradation. Three key possible MG degradation pathways, involving N-de-methylation, hydroxylation, and destruction of the conjugated chromophore, were proposed based on the results of ultra-performance liquid chromatography-tandem mass spectrometry. Life cycle assessment study was applied to evaluate the environmental impacts of the following two disposal strategies for frass wastes: Fe/FBC catalyst facilitation (scenario A) and composting treatment (scenario B) at midpoint level. Regarding ten impact categories, scenario A produced lower environmental footprint compared to scenario B, indicating that the facilitation of Fe/FBC is a financially and environmentally viable strategy for relieving the greenhouse effect, energy crisis, water toxicity, and eutrophication.
