The embodiment of the present application relates to the technical field of heavy-duty coating, and discloses a marine facility corrosion protection layer regulation and control method suitable for strong salt spray environment, which comprises preparing a self-activated intermediate paint and applying it between a primer and a topcoat to form a composite protective layer; the core is that a double-triggered mineralization precursor is contained in the main agent of the self-activated intermediate paint, the precursor is composed of BF4 ‑ loaded hydrophobic modified zeolite and zinc phosphate coated water glass microparticles; when the coating is damaged, the corrosion microenvironment of the damaged area can synergistically trigger the zeolite to release BF4 ‑ to buffer the pH, at the same time trigger the dissolution of the coated water glass microparticles and release silicate ions; the released silicate ions react in situ with cations in the environment to generate mineralization products, plugging the damaged area. The present application can actively inhibit corrosion propagation and cathodic delamination after coating damage, significantly improving the long-term reliability and service life of the protective layer.

The catalytic wet oxidation catalytic material takes acid modified montmorillonite loaded with copper oxide and optional nano ferrous sulfide as a matrix layer, and the outer surface of the matrix layer is wrapped with an active layer which is alumina loaded with nano ferrous sulfide; the matrix layer and the active layer are in a core-shell structure; the weight of the copper oxide accounts for 2-10% of the weight of the catalytic material, and the weight of the nano ferrous sulfide accounts for 5-20% of the weight of the catalytic material. The application further provides a preparation method of the catalytic wet oxidation catalytic material. The catalytic material has excellent catalytic degradation capacity for organic pollutants when used for treating organic wastewater.

This invention provides a sweet-scented black tea, relating to the field of fermented black tea preparation. It is obtained through a preparation process of withering, rolling, fermentation, and continuous light fermentation drying. Rolling involves cyclically rolling withered leaves using a light-heavy-light pressure method to obtain rolled leaves. Fermentation involves breaking up the rolled leaves and placing them in a fermentation chamber or fermentation machine for fermentation at a temperature of 28-30℃ and a humidity of not less than 90%, for 3 hours with stirring every hour to obtain fermented leaves. After fermentation, continuous light fermentation drying is performed to obtain the sweet-scented black tea. This black tea utilizes a specific tea-making process, namely, continuous light fermentation drying after fermentation by introducing a dry mixed gas. This achieves light fermentation during the drying process, allowing fermentation to continue throughout the entire drying process, improving the persistence of the fermentation process, avoiding excessive oxidation and fermentation of the tea sample, and ensuring the long-term and stable nature of the fermentation.

This invention relates to the field of wastewater treatment technology, specifically a method for treating high-salt organic wastewater containing polyenes and polyamines. This invention overcomes the problems of high toxicity of polyenes and polyamines, easy complexation with catalysts, and low biochemical efficiency under high-salt conditions in wastewater treatment. First, this invention utilizes copper-supported cross-linked chitosan to achieve specific complexation and sedimentation of macromolecules, significantly reducing toxicity. Then, it uses oxygen-rich vacancy titanium dioxide particle electrodes combined with ultrasound to efficiently break stubborn C-N bonds. Next, bimetallic catalytic ozone completely eliminates residual biotoxicity. Finally, iron-modified biochar provides a salt-resistant microenvironment and electron shuttle effect for salt-tolerant bacteria, achieving deep mineralization and denitrification of pollutants. This effectively solves the biochemical treatment problem under the dual stress of high salt and high toxicity, resulting in stable effluent quality.
