The application discloses a preparation method of a ZIF / LDH loaded biochar composite adsorbent and application thereof, and comprises the following steps: (1) mixing, calcining and washing and drying pretreated corn stalks and alkali to obtain biochar BC; (2) mixing, washing, drying and calcining a certain proportion of the biochar BC and acetate, then mixing with 2-methyl imidazole, aging, and washing and drying to obtain BC / ZIF; and (3) immersing a certain amount of BC / ZIF in a nitrate solution, stirring, standing, washing and drying to obtain a BC / ZIF8 / LDH composite adsorbent. The composite adsorbent has a layered and open structure, a large specific surface area, a large number of adsorption sites, and a nitrosamine precursor removal rate of more than 95%; has a good binding capacity and selective adsorption on small-molecule amine, histidine, protein and other nitrogen disinfection by-product N-DBPs precursors; has good dispersing performance, high utilization rate of LDH metal, stable structure, good reaction activity and good repeated use effect; and has a wide source of raw materials, low price, low production cost and high economic benefit.

This invention belongs to the field of metal end cap processing technology, specifically an automatic feeding device suitable for metal end cap processing. It includes a feeding conveyor belt for conveying and feeding metal end caps. A transfer device is provided on one side of the feeding conveyor belt for conveying and transferring stacked metal end caps. A picking arm is provided between the transfer device and the feeding conveyor belt for moving metal end caps placed in the transfer device onto the feeding conveyor belt. During the picking and feeding of metal end caps, the fixing and separating components work together to pick up and feed multiple stacked metal end caps one by one, avoiding the situation where multiple end caps stick together and are fed simultaneously. Furthermore, the mechanized separation drive, compared to manual separation, not only saves manpower but also improves separation efficiency, making it more conducive to automatic feeding operations during metal end cap processing.
