The invention discloses a processing method for improving the natural colored cotton color depth and colour and luster stability. The method comprises the steps that natural colored cotton obtained after color fixing is washed and dried; the natural colored cotton is dried, then the natural colored cotton obtained after drying is subjected to liquid ammonia treatment, and the natural colored cotton after liquid ammonia treatment is obtained; gelatin, penetrant and water are mixed to form a protein solution, then the protein solution is adjusted to reach the pH being 2.0-7.0, and a treatment solution is obtained; the natural colored cotton obtained after liquid ammonia treatment is put in the treatment solution for padding at 15-70 DEG C, so that the liquid-carrying rate of natural coloredcotton obtained after padding is 30-150%, and then cold reactor placement is conducted; the natural colored cotton after fixing treatment is obtained. By means of the method, the color of the naturalcolored cotton can become brighter, and the color is obviously deepened and become more uniform; the color fastness to washing and sunshine can be effectively improved.

The invention relates to a preparation method of a betel-nut-flavor jerky. The method is characterized in that fragmentary livestock meat is adopted as a raw material, uniformly tumbled with seasonings such as a betel nut extract at low temperature and pickled, then dried and baked to obtain meat blocks, and betel nut bittern is applied to the surface of the meat blocks using a brush, and the meat block is naturally dried. According to the invention, a jerky production process and a betel nut production process are combined to produce the series betel-nut-flavor jerky, not only can the flavor types of jerky be enriched, but also no residue is left after the betel-nut-flavor jerky is eaten, no environment pollution occurs, and the jerky is an ideal betel nut substitute food.

A treatment method for electroless nickel plating waste liquid, comprising: (1) adding calcium hydroxide to the electroless nickel plating waste liquid for reaction, filtering to obtain primary filtrate and filter residue 1; (2) adding calcium hydroxide to the primary filtrate, Then pass through the ozone oxidation reaction and filter to obtain the oxidation filtrate and filter residue 2; (3) Add calcium hydroxide to the oxidation filtrate for reaction and filter to obtain the standard filtrate and filter residue 3; (4) Combine filter residues 1 to 3 and add sulfuric acid The solution is leached and filtered to obtain the nickel sulfate primary filtrate and filter residue 4; (5) in the nickel sulfate primary filtrate, add sodium fluoride to react, adjust the pH value, let stand, and filter to obtain the nickel sulfate filtrate and calcium fluoride residue; ( 6) Add zirconium sulfate to the nickel sulfate filtrate to react, let it stand, and filter to obtain nickel sulfate purification solution and zirconium phosphate slag; (7) adjust the pH value of the nickel sulfate purification solution, react, filter, and serve. The method of the invention has high waste water treatment efficiency, no secondary discharge, nickel recovery, simple process and low cost, and is suitable for industrial treatment.

The invention proposes a crude oil pour point depressant and a preparation method thereof, belonging to the field of crude oil pour point depressant, which can well reduce the viscosity of crude oil and improve its fluidity on the basis of significantly lowering the pour point of crude oil, and has a good effect on the subsequent crushing of crude oil. Milk dehydration has no negative effects. The crude oil pour point depressant is a terpolymer formed by polymerizing high-carbon alcohol ester of unsaturated acid, polyoxyethylene polyoxypropylene ether of unsaturated alcohol and vinyl acetate. The invention can be applied to the aspect of pour point depressing of crude oil.

The invention discloses a method for improving the mechanical property of a Ce-Ga-Cu series bulk amorphous alloy. The method is characterized by comprising the step of adding a microelement Fe into the Ce-Ga-Cu series bulk amorphous alloy to form a Ce-Ga-Cu-Fe series bulk amorphous alloy. The structural formula of the Ce-Ga-Cu-Fe series bulk amorphous alloy is Ce70-xGa8Cu22Fex, wherein x is 1, 2 or 3. Compared with the corresponding Ce-Ga-Cu series bulk amorphous alloy, the Ce-Ga-Cu-Fe series bulk amorphous alloy has the advantages that the rigidity, fracture strength and plastic deformation capability are improved to a certain extent when the high thermal stability and low glass-transition temperature are kept; when x is 2, a bar made of the Ce-Ga-Cu-Fe series bulk amorphous alloy has not only the highest fracture strength and microhardness, but also about 1% compressive plasticity at room temperature. Therefore, application of a Ce-based amorphous alloy as a functional material is facilitated.

The invention relates to a treatment method for nitrated bamboo cellulose washing wastewater, belonging to the technical field of environmental protection. Move the nitrocellulose cellulose washing wastewater to container A for stirring and inject the nitrocellulose cellulose alkali boiling wastewater; observe after heating and stirring the container A, if the pH value is lower than 7, stir and add the nitrocellulose cellulose alkali boiling wastewater, When the pH value is 7-8, stop adding liquid M; move the liquid M to the vacuum evaporation container B to stir and vacuumize to raise the temperature, and collect the liquid X at this time; after 2 to 5 minutes, collect the liquid Y at this time, Stop when the remaining liquid in the vacuum evaporation vessel B is 5-10% of the initial total amount, the remaining liquid Z; liquid X is used for washing nitrocellulose; liquid Y is used for alkali boiling of nitrocellulose; liquid Z is recovered Utilization; the nitrocellulose washing wastewater has been treated. The treatment method provided by the invention can realize the recycling of the nitrated bamboo cellulose washing waste water, and effectively solve the problem of sewage discharge in the preparation process of the nitrated bamboo cellulose.

A treatment method and a treatment system for nitrochlorobenzene production waste water. The method comprises the following steps: pumping nitrochlorobenzene production waste water into an adjustment pool, adjusting the pH value to allow the waste water to be acidic, then allowing the waste water to enter an oxidation pool, adding oxidizing agents of sodium hypochlorite, calcium hypochlorite or hypochloric acid for chemical oxidation treatment, discharging the effluent from the oxidation pool into a neutralization pool, adjusting the pH value to allow the effluent to be neutral, discharging the effluent from the neutralization pool into a coagulation pool, adding coagulants of one or more than one of polyaluminium chloride, polyferric chloride, and polyacrylamide for a coagulation reaction, discharging the effluent from the coagulation pool into a sedimentation pool, allowing a supernatant obtained by sedimentation and separation in the sedimentation pool to overflow into a clean water pool, discharging the clean water that reaches the standard, concentrating and filtering sedimentated sludge at the bottom of the sedimentation pool for safety treatment, and discharging waste liquid generated during the concentration and filtration process into the adjustment pool for re-treatment. According to the invention, the removal rate of nitrochlorobenzene and other nitrobenzene compounds in effluent of the nitrochlorobenzene production waste water treated by the method of the invention is up to 99%, and the method of the invention has the advantages of high treatment efficiency, low operation cost, no secondary pollution, and the like.
