The application discloses Luzhou-flavor liquor dreg water-soluble glucose oligosaccharide and a preparation method and application thereof, and belongs to the technical field of medicines.The application extracts water-soluble glucose oligosaccharide from Luzhou-flavor liquor dreg as raw material.The main chain of the Luzhou-flavor liquor dreg water-soluble glucose oligosaccharide is composed of glucose, and the side chain comprises arabinose and glucose; the Luzhou-flavor liquor dreg water-soluble glucose oligosaccharide is composed of arabinose, galactose, glucose and xylose, and the molar ratio is 8.81:2.54:76.82:6.90.The water-soluble glucose oligosaccharide prepared by the application can obviously improve the symptoms of alcoholic liver, and has the effects of inhibiting liver damage and improving the activity of liver antioxidant enzymes.In addition, the Luzhou-flavor dreg in the application is a by-product of liquor fermentation, has high raw material yield and low cost, and the application can improve the resource utilization value of the dreg.

The application discloses a kind of mixed salt resource utilization preparation agricultural potassium sulfate and industrial grade sodium chloride, it is related to solid waste comprehensive utilization technical field, the method is removed by the step-by-step precipitation of magnesium, calcium of sodium carbonate by removing magnesium of organic matter oxidation degradation organic matter in mixed salt, impurity, then refined by ion flotation, subsequently obtain sodium chloride and potassium sulfate product by gradient crystallization in turn, finally remaining mother liquor backflow reuse, precipitate waste residue pyrolysis preparation biochar, form closed loop cycle;The application realizes the efficient degradation of organic pollutants in high-organic industrial mixed salt and the deep removal of impurities, effectively improves the refining purity of salt solution and the raw material adaptation range;At the same time, gradient crystallization is used to separate salt and closed loop cycle in whole process, directional separation is used to prepare industrial grade sodium chloride and agricultural potassium sulfate, and the mother liquor and waste residue are all converted into available resources, forming a mixed salt resource utilization system with high value utilization and harmless disposal synergy.

The present application belongs to the technical field of wet-process phosphoric acid and resource comprehensive utilization, and discloses a method for preparing phosphoric acid and calcium chloride by decomposing medium and low grade phosphate rock with by-product hydrochloric acid. (1) The phosphate rock is mixed with a hydrochloric acid solution, sodium chloride is added, and after reaction, solid-liquid separation is performed to obtain an acidolysis solution; (2) the acidolysis solution is separated and treated to obtain a phosphoric acid solution and a calcium chloride solution; (3) the calcium chloride solution is neutralized and purified by using a stepwise pH value control method; (4) the purified calcium chloride solution is concentrated, sodium chloride is precipitated and separated due to solubility difference, and is returned to step (1) for recycling, and the concentration, crystallization and drying are continuously performed to obtain a calcium chloride product. The present application effectively solves the problems of difficult solid-liquid separation and low value of by-product calcium chloride caused by the generation of silica gel in the acidolysis process of medium and low grade phosphate rock, the decomposition rate of the phosphate rock is more than 98%, high quality phosphoric acid is obtained, the full utilization of by-products is realized, and the production cost and energy consumption are significantly reduced.

This invention discloses a method for preparing arsenic-cadmium lattice mineralized and immobilized silicate mineral materials based on mechanochemical ball milling and its application. The invention aims to solve the technical problems of poor arsenic and cadmium immobilization and ineffective immobilization in existing silicate mineral materials. Preparation method: 1. Mix iron oxide yellow and serpentine evenly to obtain an iron-serpentine composite silicate mineral material; 2. Place the iron-serpentine composite silicate mineral material in a ball mill jar and ball mill it at a controlled speed to obtain an arsenic-cadmium lattice mineralized and immobilized silicate mineral material. Application: This invention involves adding the arsenic-cadmium lattice mineralized and immobilized silicate mineral material to polluted water or soil. This invention uses a mechanochemical method to form a surface bond between iron manganese oxides and serpentine, constructing a composite interface with multiple synergistic effects, improving the adsorption performance of cadmium and arsenic, and significantly promoting the diffusion and immobilization process of heavy metal ions into the serpentine lattice.
