The invention discloses a production method of distiller's grain fermentation liquid fertilizer specially applied to roxburgh rose. The distiller's grain fermentation liquid fertilizer is prepared bythe step of evenly mixing 50 to 80 parts of distiller's grain fermentation extracting solution, 0.5 to 1 part of microelement, 5 to 10 parts of seaweed meal, 5 to 10 parts of natural active organism,2 to 5 parts of potassium bicarbonate, 2 to 5 parts of natural active organism and 2 to 5 parts of natural surface active agent. A preparation method of the distiller's grain fermentation extracting solution comprises the steps: evenly stirring 50 to 80 parts of distiller's grain, 50 to 150 parts of rice washing water, 1 to 2 parts of EM microflora fermentation liquid and 0.5 to 1 part of sugar, performing composting fermentation at the room temperature to obtain a distiller's grain fermentation material, stirring and extracting through a sodium carbonate water solution, filtering and performing evaporation and condensation on obtained filtrate until the density is 1.1 to 1.2 to obtain distiller's grain fermentation extracting solution. The distiller's grain fermentation liquid fertilizerdisclosed by the invention has a good use effect, meanwhile can effectively prevent pest and disease damage to the roxburgh rose and is high-efficiency environment-friendly liquid fertilizer.

This invention provides a method for preparing bamboo fiber for textiles, belonging to the field of fiber extraction technology. The preparation method includes bamboo strip pretreatment, enzyme immobilization, and bamboo fiber extraction. The bamboo strip pretreatment method is as follows: whole bamboo is taken, crushed and cut, and bamboo strips with a length of 6-8 cm, a width of 0.5-0.7 cm, and a thickness of 0.3-0.5 cm are taken. The strips are ultrasonically treated for 25-35 min, then soaked in NaOH solution for 30-40 min, filtered, washed with deionized water until neutral, and dried to a moisture content of 15-20% to obtain pretreated bamboo strips. The bamboo fiber extracted by this invention has a tensile strength of 1.21-1.28 GPa, a breaking elongation of 4.09-4.17%, an elastic modulus of 37.15-37.26 GPa, and an average enzyme activity retention rate of 66.3-68.4% after 10 reuses.

The application discloses a kind of carbon dioxide corrosion inhibitor based on mannich base and its preparation method and application, belong to petroleum chemical industry metal material protection technical field.Main agent mannich base is with 3-amino crotonitrile, 3-hydrazine quinoline, phenylacetone, cinnamaldehyde as main, it is prepared by condensation, mannich two-step reaction, its structure is as shown in formula A.The inhibitor includes by mass percentage:mannich base A 30~40%, alkylamine 8~16%, potassium iodide 0.3~0.6%, surfactant 10~20%, organic solvent 30~60%.Mannich base A synthesis is simple, post-treatment is convenient, molecule contains quinoline, pyrazole, carbonyl, double bond, phenyl functional group simultaneously, can be well adsorbed on carbon steel surface and form dense protective film to prevent the invasion of corrosive medium.Add alkylamine, potassium iodide, surfactant, organic solvent, water solubility increases after compounding, corrosion inhibition effect is enhanced.The corrosion inhibitor has the characteristics such as small amount, high efficiency, wide application range, and has wide application prospect in oil and gas production.

This invention relates to the field of wastewater treatment technology, and more particularly to a method for enhancing anaerobic ammonia oxidation (AAO) denitrification using iron-loaded polyurethane porous materials. The method includes the following steps: Anaerobic ammonia oxidation sludge, iron-loaded polyurethane porous materials, and wastewater containing ammonia nitrogen and nitrite nitrogen are thoroughly mixed in an anaerobic reactor and reacted under anaerobic conditions at a temperature of 31-35°C. The iron-loaded polyurethane porous materials are prepared as follows: polyurethane sponge is selected as a carrier, cut and cleaned, and then immersed and stirred in a mixed iron salt solution for a period of time. The pH of the mixed solution is adjusted to alkaline, resulting in the formation of a red precipitate. The iron-loaded polyurethane porous materials are then hydrothermally synthesized. The mixed iron salt solution includes ferric chloride and ferric nitrate. The carrier material prepared by this invention, when applied to an anaerobic ammonia oxidation system, can effectively shorten the process start-up time, promote the enrichment and biofilm formation of anaerobic ammonia oxidizing bacteria, and achieve a high total nitrogen removal rate.

The utility model provides an irregular through hole texture tatting vamp, and relates to the field of spinning. The tatting vamp comprises a through hole weave and a common grain weave, the number of weave point warps of the through hole weave is two or more, the number of weave point wefts of the through hole weave is two or more, all warps and wefts of the same weave point of the through hole weave are gathered into a bundle, and all wefts of the same weave point of the through hole weave are gathered into a bundle. The through hole weave and the common grain weave are integrally and continuously woven; by adopting a specific weaving machine and a specific weaving method, the irregular through hole weave tatting vamp is woven, all warps and wefts at the same weave point of the through hole weave are respectively gathered into bundles, and air holes are formed among the weave points, so that the purpose that the pores of the weave points can be increased without twisting the warps is achieved; meanwhile, the boundary between the through hole weave and the common line weave can form an irregular curve, so that the pattern feeling is added to the fabric, the permeability of the fabric can be improved, and the problem of poor air permeability of the woven fabric is solved.

The utility model provides a tatting vamp fixed through threading of a through hole structure, and relates to the field of spinning. The tatting vamp comprises a through hole weave, a common grain weave and a consolidation line, the number of warp yarns of weave points of the through hole weave is two or more, the number of weft yarns of the weave points of the through hole weave is two or more, all the warp yarns and the weft yarns of the same weave points of the through hole weave are gathered into bundles, and all the weft yarns of the same weave points of the through hole weave are gathered into bundles. The fixing threads penetrate through holes of the through hole tissues and extend to the outer side of the vamp, and in the subsequent shoemaking process, the fixing threads extending to the outer side of the vamp are fixed in the outsole or the insole of the sole, so that the firmness of the vamp and the sole is improved.
