The utility model discloses a sealing ring with a bee groove end face and a mechanical sealing device, in the sealing ring, the sealing ring comprises a sealing end face, the sealing end face is provided with a plurality of bee grooves, and the bee grooves are uniformly arranged around the center of the sealing end face; wherein the appearance of the bee groove is an orthographic projection obtained by overlooking from the back when double wings of a bee are in an open state, the bee groove is in an axial symmetry shape, the central axis of the bee groove penetrates through the circle center of the sealing end face, and the head of the bee groove abuts against the outer side edge of the sealing end face to form a medium inlet. The dynamic pressure effect of end face fluid can be enhanced, so that the bearing capacity of an end face fluid film is improved, and the sealing operation stability is improved.

The application discloses a kind of foam ceramic-based biofilm carrier and preparation method thereof, and the application is more excellent in dispersibility and compatibility by adding modified lithium bentonite and modified activated carbon, to promote the foam ceramic-based biofilm carrier with better quality, which can significantly increase the biological affinity of the system, help to improve the biofilm efficiency and quality, and after high-energy radiation, more active sites are generated on the surface, enhancing the interaction with silane coupling agent, thereby improving the degree of surface functionalization, with higher application stability;By adding a specific binder, it helps to form a more stable cross-linked structure, and synergistically acts with the reinforcing filler, making the application mechanical properties of the foam ceramic-based biofilm carrier more excellent, and overall, a foam ceramic-based biofilm carrier with better mechanical strength and biological affinity is obtained, which is applied to the treatment of sewage by biofilm method, with excellent biofilm rate, biofilm stability and adhesion, thereby making the sewage treatment effect more significant.
