The invention relates to mouthwash for effectively inhibiting bad breath and a preparation method thereof. Main components of raw materials of the mouthwash comprise chlorine dioxide, cetyl pyridiniumchloride and zinc citrate, wherein a solvent is distilled water and the concentration of the chlorine dioxide is 200 to 500ppm; the mass percent content of the cetyl pyridinium chloride accounts for0.05 to 0.2 percent of the compound formula mouthwash; the mass percent content of the zinc citrate accounts for 0.5 to 1 percent of the compound formula mouthwash; the preparation method of the mouthwash comprises the following steps: dissolving the cetyl pyridinium chloride and the zinc citrate into the distilled water and dissolving menthol crystal into 95 percent ethanol; adding a menthol crystal ethanol solution into a water solution and stirring; meanwhile, adding glycerol; taking the chlorine dioxide powder and dissolving into the distilled water; adding a chlorine dioxide water solution into the water solution; adding the chlorine dioxide solution and stirring; uniformly mixing and adding the distilled water to obtain the mouthwash for effectively inhibiting the bad breath. The mouthwash provided by the invention has the advantages that the bad breath is effectively inhibited for long time, side effects are relatively small and the mouthwash has no obvious irritation on oral mucosa.

Slow-release Fenton-like system based on immobilized enzyme and method for in-situ remediation of groundwater pollution by slow-release Fenton-like system
ActiveCN112624508AImprove controllabilityAchieve mineralization degradationWater contaminantsMultistage water/sewage treatmentIn situ remediationEnvironmental engineering
The invention discloses a slow-release Fenton-like system based on an immobilized enzyme, and provides a method for in-situ remediation of groundwater pollution. The method mainly comprises the following steps: 1) selecting a central well and a plurality of peripheral chemical adding wells in a pre-remediated groundwater pollution area; 2) adding green rust into the chemical adding wells, then pumping water from the central well, recharging the water into underground water through the chemical adding well, and continuously pumping water until green rust appears; and 3) arranging an immobilized enzyme reactor in each chemical adding well, conducting aerating, introducing a glucose solution, pumping a small amount of water in the central well, recharging the water into underground water through the chemical adding wells, and pumping water until the concentration of effluent pollutants reaches the standard. The slow-release Fenton-like system has a pH range close to the environment where underground water is located, lasting slow release of free radicals and controllability of a degradation area can be achieved in the whole process, other pollutants cannot be introduced into the underground water, and non-toxicity and harmlessness can be achieved.

Organic and inorganic fertilizers based on vermicompost
The invention provides organic and inorganic fertilizers selecting vermicompost as a green organic fertilizer. The organic and inorganic fertilizers are characterized by comprising equal to and greater than 20% of vermicompost, less than and equal to 30% of water, equal to and greater than 3.0% of N, equal to and greater than 3.0% of P2O5, equal to and greater than 3% of K2O and trace elements, such as Fe, Mn, Cu and Zn each of which the content is greater than 0.1%. According to the invention, crops are fertilized by a combination of the organic fertilizer and inorganic fertilizer, so that the shortcomings of the nutrient deficiency of the organic fertilizer and the soil hardness easily caused by inorganic fertilizer are made up, physical and chemical indexes of the soil can be improved and soil organic matter can be updated or enriched, thereby improving product quality and enhancing disease resistance.

InactiveCN109183184AExtended service lifeAccelerate evaporationDyeing processMonocomponent polyesters artificial filamentFiberCellulose
The invention provides a preparation method of a capsule fiber and the capsule fiber and aims at improving the functional characteristic of an existing capsule fiber, wherein the preparation method comprises the following steps: preparing microfine medical stone powder sieved by using a sieve smaller than 450 meshes from medical stone; uniformly mixing pollen particles and the microfine medical stone powder according to the weight ratio of 3:2 to obtain aromatic powder; mixing an acidic dye with carbon cellulose under a vacuum environment to prepare a capsule core; blending the aromatic powderand liquid water into an aromatic liquid within the range of 40-55 DEG C; impregnating the capsule core into the aromatic liquid for 20-30 min, then, taking out and drying the capsule core to preparea functional capsule core; wrapping a hydrophilic colloid and the capsule core to form a microcapsule, adding the microcapsule into a molten polyester chip, and carrying out uniform mixing to obtaina spinning raw material; adding the spinning raw material into a spinning machine for high-speed spinning to prepare nascent fiber; and sizing the nascent fiber by using a parallel drawing machine toobtain the capsule fiber. The preparation method has the technical advantage that additional functions of the capsule fiber can be kept for a long time.
