This invention discloses a filtration and dust removal device and its usage method for candy tablet production, relating to the technical field of dust removal equipment. The device includes a candy tablet press, with an embedded industrial camera installed on one side of its outer wall. Through the coordinated use of the embedded industrial camera, a sugar powder suction machine, and three sets of filter nozzles, the size and quantity of the candy tablets can be detected, and the filtration and adsorption methods can be adjusted according to these different sizes and quantities. When the size and quantity of candy tablets are small, only the lowest wind speed is used for sugar powder adsorption and filtration, reducing energy consumption and factory costs, achieving energy conservation and emission reduction. When the size and quantity of candy tablets are large, the adsorption speed is increased, and sugar powder is adsorbed and filtered from both sides of the candy tablets during transport, facilitating secondary recycling of the sugar powder generated during transportation. Simultaneously, it prevents sugar powder from scattering and affecting the workshop production environment.

This invention discloses a lytic bacteriophage for controlling Vibrio alginolyticus in aquaculture environments. The bacteriophage, vB_ValM_R42H, belongs to the myotail bacteriophage family, is insensitive to chloroform, has a lipid-free capsid, and its preservation number is GDMCC No:67434-B1. This bacteriophage exhibits rapid adsorption, short latency, and high lysis rate, and maintains high activity over a wide temperature range (4℃~55℃) and pH range (2~11), demonstrating strong environmental adaptability. Genomic analysis shows that this bacteriophage does not contain virulence factors, antibiotic resistance genes, or lysogen-related genes, indicating high biosafety. Phylogenetic analysis indicates that it can be classified into a new genus. Due to its high lysis efficiency, good environmental stability, strong specificity, and genetic safety, the bacteriophage R42H of this invention can serve as an ideal biocontrol agent for controlling Vibrio alginolyticus disease in aquaculture.

The application discloses a Cu-Sn-S metal sulfide adsorbent for capturing Ni 2+ , and has the molecular formula K 2‑ x Cu x (H2O) x [Cu2Sn2S6], x =0.1~1.9; has a two-dimensional layered structure, each electronegative layer skeleton is sequentially composed of [Sn-Cu-S], [Cu-S] and [Sn-Cu-S] three sub-layers, wherein K + is located in the pores of two [Sn-Cu-S] sub-layers and is used for balancing the charge of the layer skeleton; when Ni 2+ is adsorbed, Cu + in the [Sn-Cu-S] sub-layer is exchanged with Ni 2+ , so that the high-efficiency and high-selectivity capture of Ni 2+ in radioactive wastewater is realized.
