The application relates to the technical field of wastewater denitrification, and discloses a composite carrier as well as a preparation method and application thereof. The composite carrier comprises porous molybdenum disulfide, the porous structure of the molybdenum disulfide in-situ grows zirconium metal organic frameworks, and the surface of the molybdenum disulfide is loaded with graphene. The composite carrier can not only serve as a place for denitrification of microorganisms, but also can improve the denitrification efficiency of the microorganisms.

This invention discloses a method for preparing nano-boehmite and its application in lithium-ion battery separators, belonging to the field of inorganic nanomaterial preparation technology. The method includes five steps: raw material calcination and activation, preparation of precursor slurry, hydrothermal synthesis reaction, washing and filtration, and drying and depolymerization. Calcination is carried out in a dynamic calcination furnace, whose exhaust mechanism can promptly remove water vapor. During discharge, the switching mechanism automatically opens the discharge cover, achieving continuous production with no material sticking to the wall and no residue. The obtained nano-boehmite is characterized by low sodium content, uniform particle size, and good dispersibility. This material can be formulated with binders and other agents to form a ceramic coating slurry. After coating and drying, a robust nano-ceramic coating is formed on the surface of a polyolefin-based membrane. This coating significantly improves the thermal stability, electrolyte wettability, and puncture resistance of the separator, thereby improving the battery's safety performance and cycle life.

This invention discloses a low-serum MDCC-MSB1 (MSB1) suspension culture medium and an inactivated chicken infectious anemia virus (TIV) vaccine. The culture medium comprises amino acids, carbon source, additives, vitamins, inorganic salts, buffer salts, and water, and further contains newborn calf serum (NBCS). Using this medium, low-cost, high-density suspension culture of MSB1 cells can be achieved, significantly improving cell culture stability. After 30 consecutive passages at a 1% volume ratio of NBCS, the viability of MSB1 cells remains above 94%, with uniform cell morphology and a clumping rate of <3%, making it suitable for large-scale bioreactor production. Furthermore, when applied to the preparation of an inactivated chicken infectious anemia virus vaccine, it can comprehensively improve virus propagation efficiency, increasing virus production efficiency by more than 25%, with a virus titer of not less than 1.0 × 10⁻⁶. 8.0 TCID 50 / ml, ensuring stable quality in large-scale production.
