The invention belongs to the technical field of industrial wastewater treatment, and particularly discloses a method for removing arsenic from sulfate acidic wastewater. The method comprises the following steps that 1, the sulfate acidic wastewater is neutralized through a calcium carbonate suspension of 5 wt%-8 wt%, and solid-liquid separation is conducted after neutralization is conducted; 2, neutralized filtrate is neutralized again through a lime milk suspension of 5 wt%-8 wt%, solid-liquid separation is conducted, and more than 98% of the arsenic is removed in the process; 3, ferric sulfate or polymeric ferric sulfate flocculent settling is conducted, and flocculent settling is conducted on the filtrate in the second step to remove the residual arsenic. The method for removing the arsenic from the sulfate acidic wastewater is low in treatment cost and simple in operation condition, and the treated wastewater can reach a corresponding national emission standard; meanwhile, high-concentration arsenic residues can be obtained, and resource recycling or stabilizing or curing of the arsenic is facilitated.

The invention provides a protein A immunoadsorption material which eliminates pathogenic antibody and the compound from plasma and the preparation method thereof. The invention discloses a polymer material coupled by agarose gel and staphylococcal protein A (SPA) and the material takes the agarose gel as vector matrix and takes polyamines reagent as a space arm, thus reacting with glutaraldehyde and finally coupling with the protein A and blocking, reducing a double bond after being activated by epoxy bromopropane. The product has high safety; by making use of the produce, the pathogenic antibody, more particularly, the immune compound pathogenic antibody can be effectively and selectively eliminated from the plasma of patients; and the invention can be applied to clinical immunoadsorptiontreatments.

The invention discloses a method for preparing transglutaminase from antarctic krill. According to the method, the cleaned antarctic krill are chopped, a buffer solution is added, the mixture is subjected to homogenate and centrifugation, a clear liquid is taken and filtered by a cellulose acetate membrane, a turbidity solution on the upper layer is removed, a filtrate is dialyzed through a sodium acetate dialysis fluid and subjected to ultrafiltration through ultrafiltration equipment, a filtered fluid is subjected to chromatographic purification through ion exchange resin, the purified fluid is subjected to ultrafiltration, concentration, and freeze drying, and purified transglutaminase is obtained. According to the method, a process is reasonable, the operation is simple, the preparation speed is high, and the purity and the enzyme activity recovery rate of extracted transglutaminase are high.

The invention discloses an anti-oxidization and anti-pollution compound nutritional block for dairy cattle and an application thereof, belonging to the technical field of blocks for the dairy cattle. The anti-oxidization and anti-pollution compound nutritional block takes molasses, urea, vitamins and mineral elements as main raw materials; a natural antioxidant substance, a traditional Chinese medicine extract and a condiment extract are scientifically compounded and the prepared compound nutritional block for the dairy cattle has moderate hardness, is moisture-proof and breakage-proof and has strong weather resistance; the content of infectious microbes of a lapping face of the block is low and is 0.015% of control group; the milk yield of milk secretion dairy cattle can be obviously improved by 19.02%; the first estrus time can be shortened for 13 days after delivery of the dairy cattle, the conception rate of the dairy cattle at a first estrus period after delivery is improved by 16.5% and the estrus rate of the dairy cattle crowd after delivery is 18.4%; the feed intake of the dairy cattle and the organism immunity of the dairy cattle can be improved effectively; the occurrence rates of nutritional diseases including dairy cattle allotriphagia, hoof rot, white muscle diseases, paralysis of the dairy cattle after delivery, rickets, mastitis, rough fur and feather and the like are reduced obviously and are averagely reduced by 3.3-16.7%.

The present invention belongs to CMF-TiO 2 ‑PDMS composite technology field, disclosed superhydrophobic CMF‑TiO 2 ‑PDMS composite materials and their preparation methods and applications. Amorphous TiO 2 Supported on carbonized melamine material (CMF) framework and treated at high temperature to obtain crystalline CMF‑TiO 2 ; Under the effect of curing agent, polydimethylsiloxane (PDMS) is coated with polydimethylsiloxane (PDMS) in the CMF-TiO by thermal curing. 2 The surface is cross-linked to form a film to obtain CMF‑TiO 2 ‑PDMS composites. The superhydrophobic CMF‑TiO 2 ‑PDMS composite material, which can not only adsorb water-soluble pollutants and oil-soluble pollutants, but also effectively solve the defects of poor hydrophobicity and stability of traditional photodegradation catalytic materials, while showing good durability, stability and UV oxidation resistance .

The present invention discloses a Stauntonia obovatifoliola propagation method, which comprises: S1, making sterile explants of Stauntonia obovatifoliola; S2, culturing the sterile explants with an induced culture medium to obtain axillary buds; S3, culturing the axillary buds with a proliferation culture medium to obtain clustered shoots; S4, culturing the clustered shoots with a strong seedling culture medium to obtain Stauntonia obovatifoliola seedlings; S5, culturing the Stauntonia obovatifoliola seedlings with a rooting culture medium to obtain the rooted Stauntonia obovatifoliola seedlings, wherein the rooting culture medium contains MS, 0.3-1.3 mg / L of indole butyric acid and 0.1-0.5 g / L of active carbon; and S6, transplanting the rooted Stauntonia obovatifoliola seedlings into a matrix to culture. According to the present invention, with the tissue culture and the matrix cultivation, the wild plant Stauntonia obovatifoliola is successfully cultivated; and the reaction conditions such as the temperature, the time and the light intensity can be regulated, the obtained Stauntonia obovatifoliola has the high survival rate, the scale production of the Stauntonia obovatifoliola is solved, and the cultivation time of the Stauntonia obovatifoliola is shortened.

The invention discloses a method for removing mist droplets in a gas by combining an expanded bed of glass spheres with a coalescer, which comprises the following steps: (1) flowing industrial air into an expanded bed of glass spheres filled with porous glass spheres, and performing a preliminary (2) Introduce the preliminary purified airflow obtained in step (1) into the coalescer for fine mist to coalesce and settle, and the purified air is discharged through the coalescer. When the residual concentration is higher than 30-40ppm, it is necessary to clean the expanded bed of glass spheres and the coalescer before reuse; the industrial gas defogging method of the present invention combines the expanded bed of glass spheres with the coalescer, During the initial adsorption process of the expanded bed, the large-sized droplets in the industrial gas are separated, and the coalescer coalesces the small-sized droplets, which can effectively reduce the residual concentration of the droplets to 30ppm and increase the yield of the target product.
