Abstract: Provided is a dust suction cabin and a nail grinder set. The dust suction cabin includes a cabin body and a dust suction device. The cabin body defines a nail grinding chamber that is used for grinding the nail of a pet, and a chamber wall of the nail grinding chamber is at least partially transparent. The cabin body further defines a dust removal port and two inlets communicating with the nail grinding chamber. One of the two inlets is used for the nail grinder to enter the nail grinding chamber, and the other is used for the pet's claw to extend into the nail grinding chamber. The dust suction device is used for sucking out the scraps generated during the pet nail grinding process through the dust removal port.

Abstract: Provided is a nail grinder that includes a housing, a grinding member, a dust suction fan, a driving member, an ultraviolet lamp, and a first illumination lamp. The housing is provided with a grinding chamber, a dust collection chamber, and a fan installation chamber, which are connected in sequence. The grinding member is rotatably arranged in the grinding chamber. The dust suction fan is rotatably arranged in the fan installation chamber. The driving member is used to drive the grinding member and the dust suction fan to rotate. The ultraviolet lamp is arranged on the housing and used for emitting ultraviolet light. The first illumination lamp is arranged on the housing, and the light-emitting side of the illumination lamp is arranged to face toward the grinding member. The technical solution of this disclosure enriches the functions of the nail grinder.

Abstract: An artificial biomembrane and a method for manufacturing the same. Raw film-forming materials, such as polyvinyl alcohol, sodium alginate and sodium carboxymethyl cellulose, are dissolved in water to form a glue liquid, into which a mixture of coal-based activated carbon powder, diatomaceous earth powder sodium acetate and single strain or multiple strains of microbial cells are added. The resultant glue liquid is immobilized using powder beds or fluidized beds to form artificial biomembranes. The artificial biomembranes can be manufactured in a large-scale, with simple process of immobilization, high efficiency and low cost. The artificial biomembranes can be applied to ecological restorations and different polluted water environments, such as industrial wastewater, sewage, fishing water, landscape water, flowing water and the like.

Abstract: The present invention relates to an artificial biomembrane and a method for manufacturing such an artificial biomembrane. The beneficial microbial strains, authorized for use in the nation, are concentrated after fermentation. Film-forming raw materials in the water, such as polyvinyl alcohol, sodium alginate and sodium carboxymethyl cellulose, are dissolved into glue liquid, into which the mixture of coal-based activated carbon powder, diatomaceous earth powder sodium acetate and single strain or multiple strains of microbial cells are added. The glue liquid are set into the spray device that is pressed to spray, such that fogdrops are landed on powder beds or fluidized beds for immobilization to form artificial biomembranes. The artificial biomembranes can be manufactured by mechanization and large-scale production, with simple process of immobilization, high efficiency and low cost.
