The invention discloses a sulfur-tolerant platinum-based catalyst and a preparation method thereof, and the preparation method of the sulfur-tolerant platinum-based catalyst comprises the following steps: weighing roasted ZrO2 as a carrier, weighing ammonium metatungstate, completely dissolving in deionized water, dropwise adding the solution until the carrier is completely immersed, and carrying out ultrasonic treatment; standing at room temperature, drying, and roasting in air at 500-600 DEG C to prepare a tungsten oxide loaded solid acid composite carrier WO3-ZrO2; and weighing chloroplatinic acid, completely dissolving the chloroplatinic acid in deionized water, dropwise adding the solution into the composite carrier, completely immersing the composite carrier, carrying out ultrasonic treatment, standing at room temperature, drying, and roasting in air at 250-350 DEG C to obtain the sulfur-tolerant platinum-based catalyst. The catalyst is simple in preparation method, has relatively strong tolerance to different sulfur species, and has good low-temperature catalytic performance and catalytic stability to low-carbon alkane.

The application discloses a cutinase-amylase synergistic desizing process for sizing polyester fabric with starch and WPET mixed sizing material, and aims at the shortage of the traditional high-temperature strong-alkali desizing process, so that the sized polyester fabric is placed in the same desizing working solution, the synergistic effect of the cutinase and the amylase is utilized under the near-neutral and medium-temperature conditions, and the synchronous and efficient removal of the starch and the WPET mixed sizing material is completed in one step. The method has a simple process flow, can effectively remove the mixed sizing material, can significantly reduce the damage to the polyester fiber, can improve the fabric hand feeling, and has the outstanding environmental protection advantages of low energy consumption and small wastewater pollution load.

The application discloses a method and device for treating oily sludge by using microorganisms, and comprises the following steps: mixing oily sludge, water, a microbial agent and nutrients to obtain a culture system; and adjusting the temperature and pH of the culture system to degrade oil hydrocarbons in the oily sludge. The application screens out a good strain for degrading residual oil hydrocarbons in oily sludge obtained after thermal chemical cleaning, and improves the culture conditions to realize efficient degradation.
