The utility model discloses a spray system and exhaust treatment device, including jar body, circulating pool, circulating pump and spray set, the liquid inlet end of circulating pump is connected with circulating pool through pipeline, the liquid outlet of circulating pump is connected spray set through header, still include dosing pump, the liquid inlet end of dosing pump is connected with jar body, the liquid outlet of dosing pump is connected with header through dosing pipe, still be connected with detection tube on the header, be provided with pH detector on the detection tube. Compared with prior art, the new dosing of the utility model is diluted through header, and then is reacted through spray set and exhaust gas, and then is collected by circulating pool, at this moment, the neutralization liquid pH in washing tower pool is monitored by pH detector, so it will not be influenced by dosing transiently, and the single dosing amount of dosing pump can also be optimized, so that the neutralization liquid keeps stable pH, reduces the start-stop frequency of dosing pump, and reduces the risk of leakage at pump related interface.

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.

This invention relates to the field of cosmetic technology, specifically to a salicylic acid supramolecular complex, its preparation method, and its applications. The components include salicylic acid, panthenol, and cyclodextrin; the weight ratio of salicylic acid to panthenol is (20-79):(40-59). The salicylic acid supramolecular complex prepared by this invention improves upon the inherent defect of salicylic acid's poor water solubility due to its lipid solubility. Furthermore, the prepared salicylic acid supramolecular complex maintains good solubility in various complex formulation systems containing commonly used cosmetic solvents such as ethanol and polyols.

The application discloses injectable long-acting collagen and a preparation method and application thereof, and belongs to the technical field of collagen preparation. The application solves the problems of rapid degradation and insufficient mechanical property of collagen after injection into the body, and the problem of inability to have biological safety, good biological activity and injectability. The long-acting collagen is prepared by taking methoxypolyethylene glycol active ester and collagen as raw materials. Amide reaction is caused between the methoxypolyethylene glycol active ester and lysine residues on the collagen, hydrophilic PEG is introduced on the surface of the collagen, a hydration layer is formed, biological enzymes are hindered from contacting the collagen, collagen degradation is delayed, and the single-arm structure of the methoxypolyethylene glycol active ester can avoid product agglomeration and abnormal viscosity caused by excessive cross-linking. The long-acting collagen has a long retention time in the body, has no obvious cytotoxicity, has high biological safety, and maintains cell proliferation, migration and adhesion activity and biological repair functions.

This invention discloses a reverse osmosis pure water production method and equipment based on the synergistic purification of a two-stage membrane module, relating to the field of wastewater treatment technology. In the water quality monitoring stage after pretreatment, this invention performs preliminary feed water optimization on the desalination process of the reverse osmosis module based on acquired ion migration state data to reduce the scaling rate on the reverse osmosis membrane surface. Then, based on the salinity of the feed water at the inlet corresponding to the first-stage reverse osmosis membrane after the preliminary feed water optimization, pressure-flow rate synergistic control is implemented for the pressure fine desalination process of the first-stage reverse osmosis membrane, while simultaneously adjusting the circulation flow rate. Finally, based on the conductivity at a designated location within the feed water buffer tank of the first-stage reverse osmosis membrane, and combined with the feedback status of the permeate water quality from the second-stage reverse osmosis membrane, the feed water parameters of the reverse osmosis module are adjusted. This achieves refined, adaptive, and synergistic control of the reverse osmosis module, effectively solving the problem of desalination efficiency fluctuations caused by pressure difference changes in the application of two-stage membranes in existing technologies.
