The invention discloses a metal cutting fluid and a preparation method thereof.The metal cutting fluid is prepared from base oil, sucrose fatty acid ester, deionized water, glycerin, a lubricant, an antirust agent, a penetrant, modified molybdenum disulfide and phase-change heat storage microcapsules, the phase-change heat storage microcapsules can absorb heat and reduce temperature, heat generated in the cutting machining process can be taken away in time, and the cutting efficiency is improved. Compared with the existing base oil, the metal cutting fluid has the advantages that the temperature rise is obviously reduced, the metal cutting fluid cannot be decomposed due to high temperature, the volatilization is not easy, the service life of the cutting fluid is prolonged, the use amount of the cutting fluid can be reduced, the metal cutting fluid has good lubricity, rust resistance, corrosion resistance and stability, and the cutting quality can be 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.
