According to a biogas liquid reducing treatment and a biogas collaborative purification system and purification method disclosed by the present invention, by adding plant ash into the biogas liquid, alkalinity and pH value of the biogas liquid are increased, biogas liquid COD and suspended matter concentration of the biogas liquid are reduced, and by film decompression concentration technology, ammonia is recovered from the biogas liquid and biogas liquid concentration is performed, and therefore an objective of ammonia nitrogen content control in the biogas liquid and biogas liquid reducing treatment is achieved. In the biogas liquid film decompression process, ammonia enrichment can be further achieved, biogas can be desulfurized and decarburized at the same time by using enriched ammonia from the biogas liquid, and therefore preliminary purification of the biogas is achieved, then ammonia gas (NH3) entrained in the biogas is washed and CO2 in the biogas is further absorbed by using concentrated biogas liquid with high pH value, and therefore the biogas is purified and nitrogen content in the biogas liquid is controlled. The present invention can realize the biogas liquid reducing treatment, increase the nutrient content in the biogas liquid, and ensure that the ammonia nitrogen content is in a reasonable utilization range; and meanwhile the present invention is relied on low grade energy, and can therefore reduce costs.

The invention discloses a halal mushroom beef sauce and a preparation method thereof, belonging to the technical field of food seasonings. The halal shiitake mushroom beef sauce includes the following raw materials in parts by weight: 30-300 vegetable oil, 10-100 diced beef, 2-20 dried red pepper, 2-10 chili sauce, 20-60 shiitake mushroom, 2-50 garlic, Onion 1-10, ginger 1-20, edible salt 2-15, mixed soy sauce 0.3-3, white sugar 1-5, pepper 0.8-2, spices 0.1-5. The beef is specially marinated, quick-frozen, and then fried with oil to remove the mutton and increase the aroma, rich in nutrition, and crispy in taste. The invention has fine material selection, rigorous and scientific formula, taking into account the requirements of nutrition, taste, color and other aspects, and the process is scientific and reasonable. The aromas of beef, mushrooms, chili sauce, and spices are harmonious, and the taste is crisp and chewy.

The invention provides a method for preparing fermentable sugar and lignosulfonate from furfural residues. The method comprises the following steps of 1, ethanol and sulfite-based pretreatment comprising that furfural residues reacts with sulfite in an ethanol solution and reaction products are subjected to solid-liquid separation, 2, countercurrent washing comprising that the solids obtained by the step 1 are subjected to multistage countercurrent washing by an ethanol washing liquid, 3, enzyme hydrolysis comprising that the solids subjected to the multistage countercurrent washing are subjected to cellulase hydrolysis, and 4, ethanol recovery comprising that the liquid obtained by the solid-liquid separation in the step 1 is mixed with the washing liquid recovered after the countercurrent washing in the step 2 and the mixed solution is subjected to pressure reduction condensation to form ethanol and lignosulfonate. The method utilizes combination of an organic solvent method and a sulfite method. Through the sulfite method, furfural residues are pretreated so that furfural residue sample hydrophily is improved and lignin removal and hydrolysis rate increasing are realized. Through the organic solvent method, the raw materials are pre-treated so that pretreatment liquid recovery and recycle are realized and a production cost is reduced.

The invention discloses a kind of based on 5A and Fe 3 O 4 The method for catalytic pyrolysis of waste circuit boards with composite additives includes the following steps: S1. Crushing the waste circuit boards, extracting non-metallic powders into a pyrolysis furnace, and adding composite additives; S2. Heating the above materials to 500-600° C. , keep for 1.5-2.5 hours until complete pyrolysis, and collect pyrolysis oil; the composite additive is composed of the following components by weight: molecular sieve 5A 25-80 parts, Fe 3 O 4 75 to 20 servings. The invention can simultaneously realize dehalogenation and lightening of the waste circuit board pyrolysis oil, can be widely used in the treatment, disposal or resource utilization of the waste circuit board, and has a good application prospect.

The invention discloses a flat tail rope dismantling machine, which comprises a chassis. A cutting structure is arranged in the middle of the chassis. The cutting structure includes a driving part and a cutter part. The driving part includes a driving bracket. A cam is arranged in the center, and a drive motor is connected to one side of the rotating shaft. The cutter part comprises a spring rod seat and a cutter seat, a spring rod is arranged on the spring rod seat, and a spring is connected to the top of the spring rod. The tilting hinge on the cutter seat is connected with a cutter, and the front end of the cutter is connected with the lower end of the spring. The rotation of the cam can intermittently press the top of the cutter to move the cutter down. The invention cuts off the braided wire of the flat tail rope from the middle through the cutting structure, and then separates the main core wire from the braided wire by using the rope dividing structure through the pulling of the rope receiving drum. The dismantling machine can efficiently disassemble the flat tail rope, consumes less manpower, and the dismantled main core wire can be reused, thereby achieving the purpose of repairing old and waste, and saving costs.
