The invention discloses an air purifying agent, which is composed of component A and component B. The component A is a liquid reactant prepared by percarbamide, diammonium phosphate, ammonium chloride, sodium lignosulfonate, tea polyphenol, water-soluble essence, and deionized water, while the component B is a solid reaction adsorbent prepared by a porous adsorbent, tourmaline, and a load reaction absorbent. Compared with similar products on the market, the air purifying agent of the invention has the advantages of rapid cleaning and lasting effectiveness. With the dual efficacy of sterilization and disinfection, and volatile pollution gas clearing, the air purifying agent has thorough effects and can generate objects with low toxicity or no toxicity. Characterized by easily available rawmaterials, simple preparation, low cost, and convenience for industrial production, the air purifying agent provided in the invention is proved by experiments to have a removal effect up to over 92% for high, medium and low concentration pollution.

The invention relates to a method for controlling athetis lepigone pest, which comprises a step of enabling contact between athetis lepigone pest and Cry1A protein. According to the invention, Cry1A protein capable of killing athetis lepigone is generated in a plant body to control the athetis lepigone pest. Compared with the agricultural control method and chemical control method of the prior art, the method provided by the invention protects the full child-bearing period and full plant to control the invasion of the athetis lepigone pest, avoids pollution and residue, realizes a stable and thorough effect, and is simple, convenient and economical.

The invention provides a method for extracting rhenium from rhenium-rich concentrates. The method comprises the following steps of: mixing the rhenium-rich concentrates with quick lime, grinding a mixture, feeding oxygen-enriched air into the mixture, and roasting the mixture at a temperature of 400-900 DEG C; sizing and immersing the roasted mixture by using water, and filtering after the immersion is finished; adding an impurity removing agent into the filtered liquid so as to remove calcium and trace heavy metal ions; filtering after removing impurities; and carrying out ion exchange process on the filtered liquid, which is subjected to impurity removal and filtering, through anion exchange resin, obtaining ammonium rhenate solution after desorption, and obtaining ammonium perrhenate through reconcentration and crystallization. According to the method provided by the invention, quick lime oxygen-enriched roasting and water immersion are used, so that the operations of decoppering, arsenic removal and desulfuration are carried out, therefore rhenium, arsenic and sulfur are oxidized sufficiently under the oxygen enrichment condition; the rhenium, arsenic and sulfur are combined with calcium oxide, so that insoluble substances are generated; the effects of removing copper, arsenic and sulfur are more thorough in the water immersion condition, and the disadvantage that the calcium content is high in the quick lime roasting and water immersion technology is solved through using the impurity removing agent to remove impurities; and the recovery rate of rhenium is high, so that the method provided by the invention is favorable to industrialized application.

The invention discloses a crushing equipment for urban waste treatment, which comprises a crushing box, the top of the crushing box is provided with a feeding port, the middle part of the back of the crushing box is fixedly connected with a first fixing plate, and the top of the first fixing plate is fixedly connected to the There is a first motor, and the output shaft of the first motor is fixedly connected with the first rotating shaft. The crushing equipment used for municipal waste treatment effectively separates the residual moisture in the materials and waste, making it easier for workers to classify waste, saving labor intensity and time for workers, and achieving high crushing efficiency and environmental protection. The effect of good performance can effectively avoid the blockage of the sewer caused by the direct discharge of garbage, which is safe and environmentally friendly. It solves the problem that the crushing effect of some existing garbage disposal devices is limited, and the blade design is unreasonable, resulting in fragile blades and inconvenient maintenance. Furthermore, the crushing of the rubbish is not uniform enough, and the crushing efficiency is poor, which affects the problem of the follow-up treatment of the rubbish.

The invention relates to a method for controlling Athetis lepigone pests. The method includes contacting Athetis lepigone pests with Cry1A.105 protein. According to the invention, the Athetis lepigone pests are controlled by the Cry1A.105 protein that is generated in plants and can kill Athetis lepigone. Compared with the agricultural control method and chemical control method employed in the prior art, the method provided by the invention provides whole growth period and whole plant protection to plants so as to prevent and control disoperation of Athetis lepigone pests. Being simple, convenient and economical, the method provided by the invention has no pollution, no residue, as well as stable and thorough effects.
