The application discloses a nuclear industry waste transfer equipment, which comprises a grab, a turnover device, a transfer device, a cleaning device and a cover taking and sealing device, the turnover device is used for carrying the turnover of an inner barrel of a circulating barrel, the transfer device is used for supporting the movement of the cleaning device and the cover taking and sealing device, the cleaning device is used for cleaning an outer barrel of the circulating barrel, and the cover taking and sealing device is used for taking and sealing a cover of the circulating barrel; the grab moves along a straight line direction, a grabbing position of the grab intersects with a turnover stroke of the turnover device and a transfer stroke of the transfer device, and the end of the grab is arranged with the circulating barrel, so that the grab can respectively take and place the inner barrel from the circulating barrel and the turnover device, take and place the cleaning device and the cover taking and sealing device from the transfer device, and respectively hold the cleaning device and the cover taking and sealing device to perform cleaning, cover taking and cover sealing on the circulating barrel. The equipment can efficiently realize waste transfer operation, avoids the introduction of human error, and improves system safety. The application further provides a nuclear industry waste transfer method.

This invention discloses a method for phytoremediation of cadmium-arsenic co-contaminated soil based on crop straw enhancement, comprising the following steps: S1, soil tillage and preparation; S2, modification of straw powder; S3, application of straw; S4, planting of remediation plants; S5, harvesting of plants: after the remediation plants have grown to maturity, they are harvested from the soil as a whole, completing the soil remediation. The method for phytoremediation of cadmium-arsenic co-contaminated soil based on crop straw enhancement provided by this invention, by applying specific high doses of straw in two forms—modified straw powder and straw segments—to the surface and deep soil layers respectively, can rapidly activate soil microbial activity, directionally regulate the soil microbial community structure, and enhance the activation and absorption of cadmium by kenaf; simultaneously, the microbial community macroscopically passivates arsenic in the soil, enhancing the arsenic capture and accumulation capacity of kenaf roots, thereby significantly improving the remediation of the entire contaminated soil.

This invention discloses a low-voltage cable junction box with an automatic drainage and dehumidification structure, including a junction box body. A dehumidification chamber is installed at the top of the junction box body. A semiconductor heating element is installed inside the dehumidification chamber, dividing the internal space of the dehumidification chamber into a condensation chamber and a heat dissipation chamber. The two sides of the semiconductor heating element are a cold surface and a hot surface, respectively. The cold surface is placed in the condensation chamber, and the hot surface is placed in the heat dissipation chamber. This invention uses the cold surface of the semiconductor heating element to condense water vapor in the air into liquid water. Simultaneously, multiple condensation screens are provided. A first heat-conducting surface quickly transfers cooling energy to the condensation screens, cooling them below the dew point temperature. When air flows through, water vapor more easily condenses into liquid water, adhering to the surface of the condensation screens and dripping to the bottom of the condensation chamber. This effectively reduces the humidity inside the junction box, reduces the risk of electrical components getting damp, and extends the service life of the equipment.
