This invention discloses a method and system for treating landfill leachate stock, belonging to the field of wastewater treatment technology. The method includes the following steps: first, adding an appropriate amount of acid to the landfill leachate and stirring until homogeneous to obtain an acidic solution with a pH value below 1.5; then, adding silicate cement to the acidic solution in one go or in small amounts multiple times, mixing thoroughly, and allowing it to settle until solids precipitate before discharging the liquid to the external environment or transporting it to the next process. The total amount of silicate cement added is 6%-10% of the mass of the acidic solution. This method can simultaneously treat TP, TN, and NH3 in landfill leachate. 3 Removal of -N and COD, TP, TN, NH 3 The removal rate of nitrogen (-N) can reach over 75%, and the COD removal rate can reach over 30%. The levels of recalcitrant organic macromolecules and benzene ring compounds are significantly reduced. The organic matter in the water sample is reduced, and the molecular structures are simpler and smaller, which is beneficial for biological decomposition and utilization. The system has a simple structure, is easy to use, and significantly reduces water treatment costs.

This invention discloses a strain of *Lactobacillus salivarius* CCFM1332 with multi-target regulatory effects and its application in periodontitis, belonging to the field of microbial technology. This invention yields a strain of *Lactobacillus salivarius* CCFM1332, which not only has vaginal immunomodulatory effects but also alleviates periodontitis. Specifically, it can: promote the secretion of antimicrobial peptides by vaginal epithelial cells VK2 / E6E7; reduce the periodontal probing depth in rats with periodontitis; reduce the number of pathogenic bacteria in the oral cavity of rats with periodontitis; downregulate the levels of serum inflammatory factors IL-1β, IL-6, and IL-17A; and reduce alveolar bone loss in rats with periodontitis, effectively alleviating alveolar bone resorption in rats.

The application discloses a catalyst, a preparation method thereof, and a process and equipment for synthesizing NS by oxidation. The activated carbon loaded composite catalyst claimed by the application comprises a main catalyst and an auxiliary catalyst, wherein the main catalyst is 2,4,6-trihydroxy pyrimidine, and the auxiliary catalyst is one or both of stannous oxide and palladium suboxide. In the application, the main catalyst and the auxiliary catalyst can be more adsorbed in the pore structure of activated carbon, and in the process of synthesizing rubber accelerator NS by oxidation, the reaction time of the reaction of synthesizing rubber accelerator NS by oxidation can be effectively shortened.

The invention discloses a sewage treatment method, and belongs to the technical field of water, wastewater, sewage or sludge treatment. According to the invention, halotolerant bacillus, halomonas sphaeromonas and an embedding medium containing a nano synergist are combined to finally form a carrier, and an immobilized strain preparation is obtained. When the compound is applied to a high-salt organic wastewater degradation experiment, COD (Chemical Oxygen Demand) in water quality indexes of a compound group is 51.3 mg / L, ammonia nitrogen is 5.9 mg / L, total nitrogen is 10.6 mg / L, and volatile phenol is 0.23 mg / L, so that the compound group is superior to a salt-tolerant bacillus group using a single strain, a stone spring halomonas group using a single strain, a magnesium synergist group using nano magnesium particles and a zinc synergist group using nano zinc particles. Therefore, after the halotolerant bacillus and the halomonas
