The invention relates to an advanced water treatment technique for pollution removal through heterogeneous catalytic ozonation. Directed at the disadvantage that a conventional powdery catalyst is unfavorable for realizing separation and inactivation in a water phase, an assembly method for a novel manganese-cobalt complex oxide nanoparticle catalyst-loaded ceramic membrane is provided. The assembly method aims to combine heterogeneous ozonation with a ceramic membrane filtration technique, and utilizes a ceramic membrane structure and active components (MnO2 and Co3O4) on a catalytic layer to catalyze ozone so as to generate -OH with high oxidation capacity, wherein organic compounds can realize reinforced removal of pharmaceutical and personal care products (PPCPs) like 2-hydroxyl-4-methoxybenzophenone in water through direct reaction with molecular ozone or reaction with -OH generated by ozone decomposition; meanwhile, ozone can react with humic acid and natural organic matters (NOMs) in the water, so the formation of membrane pollution is effectively controlled. The manganese-cobalt complex oxide nanoparticles are loaded on the surface of the ceramic membrane, so separation of the catalyst from the water is realized, and a novel method for cleaning and repeated use of the catalyst is provided.

ActiveCN110271224ASync outImprove processing qualityBag making operationsPaper-makingZno nanoparticlesMaterials science
The invention discloses a preparing method used for a food vacuum freshness retaining compression bag. The food vacuum freshness retaining compression bag is composed of an aluminum foil bottom layer and polyethylene coating. The aluminum foil bottom layer is composed, by weight percent, 45% of aluminum powder, 25% of polyethylene resin, 15% of nanopowder, 10% of glycerin monostearate, 3% of paroline and 2% of bamboo charcoal particles; the nanopowder is formed through blending of nanosilicon dioxide powder, nanometer titania powder and nano-zinc oxide powder according to the weight percent of 3:1:1; through combination of the ultraviolet shielding effect of the nanopowder in the aluminum foil bottom layer and ultraviolet absorbing effect of 2-hydroxide radical-4-methoxybenzophenone in the polyethylene coating, the food vacuum freshness retaining compression bag can be sufficiently protected, and the conditions that under long-term light irradiation, color is prone to changing, embrittlement is prone to happening, the packaging food goes bad, and the use effect is greatly affected are avoided.
