The surface self-cleaning coating is capable of effectively preventing graffiti and resisting scaling, and self-cleaning; heavy metals or other toxic substances such as organic tin are not contained in the formula, and no chemical surfactant and alkaline products are adopted, and therefore, the film formed after the coating is cured has better durability and the surface of the film cannot be damaged by effective cleaning.

The invention relates to a method for promoting hydrolysis of sludge to produce acid by using a biosurfactant alkyl polyglucoside. The invention aims to solve the problem that the chemical surfactant, which is used in the existing method for promoting anaerobic fermentation of surplus sludge to produce acid by using a chemical surfactant, is toxic and non-biodegradable, and thus, can result in secondary pollution. Secondary sedimentation tank sludge in a sewage treatment plant is used as the raw material to perform anaerobic fermentation under the condition of adding the biosurfactant alkyl polyglucoside. The biosurfactant alkyl polyglucoside used in the method not only has the characteristics in common nonionic and anionic surfactants, but also has the characteristics of high surface activity, favorable ecological safety and high compatibility, and can improve the leaching of organic substances and promote the fermentation of surplus sludge to produce acid. The invention has favorable reference value for practical application and short-chain fatty acid reclamation in the process of sludge hydrolysis to produce acid.

The invention discloses a safe, skin-friendly, specialized sterilizing, environment-friendly efficient decontaminating aerobic soaking powder composition. The composition is prepared from the following raw materials by mass percent: 20-40% of activity enhancer, 20-50% of plant surfactant, 5-20% of external stabilizer, and 10-25% of other additives, wherein the activity enhancer is prepared from bio-enzyme preparation, whitener and activator, and the plant surfactant is selected from any one or more of fatty acid methyl ester sulfonate, alkyl glycoside, sapindoside, tea saponin and gleditsioside. In the washing powder composition, plant surfactant replaces chemical surfactants in traditional washing powder, further the plant surfactant is made of natural plants and does no causes pollutionin processing, so that the final product has no toxicity to human body, has small irritation and is easy to biodegrade.

The invention provides a method for degrading hydrocarbon pollutants in oil field oily sludge by using microorganisms. The method comprises the following steps of: S1, chemical thermal washing: takingoily sludge, adding clear water according to a certain liquid-solid ratio, mixing the clear water with the oily sludge, adding a chemical surfactant, and performing heating and stirring in a reactionkettle, conducting centrifugal separation after cleaning, collecting and recycling an upper-layer oil phase, and obtaining a solid-state layer to be treated; S2, biological thermal washing: taking the solid-state layer obtained in the step S1, adding clear water according to a certain liquid-solid ratio, mixing the clear water with the to-be-treated phase of the solid-state layer, adding a biological surfactant, and arranging an obtained mixture in a reaction kettle so as to heat and stir the mixture, conducting centrifugal separation after cleaning, collecting and recycling an upper-layer oil phase, and obtaining a solid-state layer is to be treated; and S3, microbial degradation: mixing the solid-state layer with wood chips, and adding a compound microbial agent, and then carrying out compost degradation. The oil content of the oily sludge treated by the method is less than or equal to 0.1%, and the content of C4-C20 is less than or equal to 0.01%.

The invention relates to a method for modifying magnetic bentonite by a biosurfactant. The method comprises the steps of firstly burying straws and rice husks in farmland soil for composting, performing enrichment culture on compost and domesticating a biosurfactant to generate a bacterial strain, continuously performing fermental cultivation, re-suspending fermentation liquor by using dichloromethane, filtering, extracting, centrifuging, and collecting sediment, thus obtaining a purified biosurfactant. The purified biosurfactant is used for replacing a conventional chemical surfactant, modifying the magnetic bentonite, and preparing to obtain a novel adsorber; the novel adsorber is applied to removal of uranium in low-concentration uranium-containing wastewater. The adsorber has good adsorptive property, needs main raw materials of agricultural waste biomass and natural minerals, is pollution-free to environment, and truly realizes resource conservation and environment friendliness. The method is simple, mild in reaction condition, and easy in magnetism control, and the uranium content in the low-concentration uranium-containing wastewater with the concentration of 0.45-0.55 mg / L can be reduced by 95 percent or more.

The invention discloses a preparation method of a dielectric material for a high energy storage capacitor, the invention relates to the technical field of dielectric materials, the preparation methoduses polyaniline coated with inorganic nanoparticles as a filler, polyvinylidene fluoride as polymer matrix, metal Ni as the load. Firstly, the surface of inorganic nanoparticles is modified by physical ball milling and chemical surfactant, a supercritical fluid reaction is adopted to coat polyaniline on the surface of the inorganic nanoparticles, so that a composite fill is prepared, the composite fill and the polyvinylidene fluoride are spun into a fibrous membrane by melt electrospinning, at last, the metal Ni load and the polyvinylidene fluoride are composited on the fiber membrane by magnetron sputter, the load of the metal Ni not only helps to fill the high porosity of the electrospun fiber film, but also helps to maintain high breakdown field strength, high energy storage density, high dielectric constant and low dielectric loss of the dielectric material, and the composite dielectric material has high energy storage performance.
