The invention belongs to the field of biochar adsorbing materials, and relates to a method for preparing modified biochar with aquatic plant waste and hematite. The method includes the following steps: (1) naturally drying aquatic plants prior to crushing to obtain aquatic plant powder; (2) crushing the hematite to obtain hematite powder; (3) weighing the hematite powder prior to putting the hematite powder into deionized water, and performing ultrasonic treatment to obtain suspension; (4) weighing the aquatic plant powder, soaking the aquatic plant powder in the suspension, and stirring and drying to obtain fully mixed aquatic plant and hematite mixture; (5) weighing the fully mixed aquatic plant and hematite mixture, putting the mixture in a batch-type atmosphere furnace, and feeding nitrogen into the furnace; performing temperature programming to the target temperature, and maintaining final-temperature pyrolysis; after the pyrolysis process is finished, obtaining the target product, namely the modified biochar. The modified biochar has strong adsorbability in nitrate and phosphate, high in stability and reusable.

The invention relates to a manufacturing method for delicious pork slices. To overcome the influence of too much intake of pork products on a human body, the manufacturing method for the delicious pork slices is provided. The manufacturing method comprises the steps of cutting the pork into the pork slices with the thickness of 2-4 mm; immersing the pork slices in an immersion liquid for 10-30 minutes; heating the immersion liquid with the pork slices and cooking for 0.5-1 h; fishing the pork slices out; draining the liquid; packaging and sterilizing. The manufacturing method is characterized in that, based on 100 parts by weight of the pork slices, the immersion liquid comprises, by weight, 1-5 parts of red yeast, 1-10 parts of rice wine, 20-30 parts of soy sauce, 1-5 parts of dried ginger, 10-20 parts of white sugar, 1-5 parts of spices, 1-5 parts of sodium bicarbonate, 15-30 parts of seaweed and 50-60 parts of water. The pork slices processed by the method can effectively prevent damp and hot proliferation in a stomach after being taken, and gives health to a human body while guaranteeing nutrition of the human body.

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.

The invention is about a method of marking ink which is only used to defend fake. The composition of it is: lipidol or lipid, surface active agent, integration agent, water, buffering agent. Their mass percents are: 1,2-hexylene glycol: 5%-15%, butanol: 1-5%, DH-1: 5-10%, EDTA: 0.1-0.5%, MS-1: 0.1-1%, water: the rest. The process is: a. dissolving the colorant in water, b. put the correct percent of 1,2-hexylene glycol and butanol into the solvent, then dropping the MS-1 and EDTA solution when mixing the solvent for 30-50 min, c. put the rest precent of water into the printing ink box. The picture and word would be shown red fluorescence in the UV but blank in the usual light.

The invention discloses a molecular film type automotive nitrogen and oxygen separation device which comprises a turbocharger, a nitrogen and oxygen separator, a gas inlet valve, a gas outlet valve, a negative pressure pump and an electric control throttling valve. The turbocharger is driven by a turbine in an automobile turbocharger, so that the air is compressed to be conveyed to two paths of the nitrogen and oxygen separation device, the nitrogen and oxygen separation device can separate oxygen from the air, the air with high oxygen content is output, and the air is supplied to an engine for use through the gas outlet valve. The two paths of the nitrogen and oxygen separation device work alternately, when the temperature of the two paths of the nitrogen and oxygen separation device is too high to influence oxygen production efficiency, a main air inlet pipeline is opened to provide air normally by controlling the opening degree of the electric control throttling valve, and thus the phenomena of gas circuit plugging and engine stalling are avoided. According to the automotive nitrogen and oxygen separation device, the two branch paths work alternately, high concentration oxygen can be supplied to the engine continuously so that fuel can burn and act, and the burning utilization rate of the fuel is improved.
