The invention provides antibacterial and mildew-proof corrugated paper and a preparation method thereof, and belongs to the technical field of packaging materials. According to the corrugated paper, the efficient antibacterial agent is doped into the paper base material, and the paper base material is packaged through a microcapsule technology, so that uniform distribution and long-acting release of the antibacterial agent in the paper are ensured. The preparation process comprises the steps of paper pulp preparation, antibacterial agent preparation, raw paper preparation, antibacterial protection layer coating, corrugated paper forming and the like. The antibacterial and mildewproof corrugated paper has excellent antibacterial and mildewproof effects, can keep good physical properties, is suitable for packaging products such as food, medicines and cosmetics with strict requirements on sanitary conditions, effectively prevents microbial contamination and guarantees product quality and safety.

This application discloses a seaweed oligopeptide fertilizer for promoting root growth and seedling development, and its production process, belonging to the field of fertilizer technology. The fertilizer, by weight, comprises: 2-10 parts seaweed oligopeptide complex, 1-8 parts seaweed extract, 10-30 parts compound amino acids, 1-10 parts blueberry pomace, 20-50 parts oxytetracycline waste decomposition products, and 30-60 parts recycled organic matter from kitchen waste. By combining seaweed oligopeptides with chitosan to form a complex, the stability of the active ingredients is improved; simultaneously, the synergistic utilization of oxytetracycline fermentation waste, kitchen waste, and blueberry pomace achieves resource utilization. Experiments show that this fertilizer significantly promotes crop root growth and seedling development.

The utility model relates to a carbon dioxide electro-catalytic reactor, which comprises an anode chamber, a cathode chamber and an anode chamber, a mixed gas containing carbon dioxide and water is introduced into the cathode chamber; the anode chamber and the cathode chamber are separated by the functional layer, the functional layer comprises a cathode catalyst layer located on one side of the cathode chamber and an anode catalyst layer located on one side of the anode chamber, and the functional layer is further provided with an anion exchange layer located between the anode catalyst layer and the cathode catalyst layer. According to the carbon dioxide electro-catalytic reactor, the mass transfer resistance of the functional layer is reduced by improving the functional layer, so that the reaction rate and the reaction efficiency of the reactor can be improved, and the conversion rate of a reaction system is improved. Specifically, a functional layer of a multi-layer membrane in the prior art is simplified into a single ion exchange membrane, and a two-cavity structure is formed, so that the structure of the functional layer is simplified, and the purpose of reducing the mass transfer resistance of the functional layer is achieved.
