The invention provides a method for preparing ZIFs by utilizing zinc-containing wastewater and loading them on loofah, and for advanced treatment of organic wastewater. The preparation method is as follows: first, the activated loofah is transferred to 2-methylimidazole solution for ultrasonic dispersion; then, under stirring, the waste water solution is added dropwise; finally, the loofah is taken out, washed and dried to obtain ZIFs/loofah composite material. The invention uses zinc-containing wastewater as a raw material to prepare ZIFs for photocatalytic degradation of organic wastewater, so as to achieve the purpose of treating waste with waste. At the same time, the regenerable, low-polluting loofah is used as the carrier of the metal-organic framework to realize the rapid separation and recycling of the catalyst and avoid secondary pollution. The invention prepares an efficient environment-friendly photocatalyst, and provides a preparation method with low cost, environment-friendly, simple and easy operation. |
